"Backhoe Fade" or "Target Practice"?

FOA Instructor Mark Goodwin-Asire of Brierwood Technical Institute in the Atlanta area contributed this interesting article on damage to fiber optic cables:

For years we have taught our students that the number one cause of OSP damage is accidental dig up. Well I guess that just depends on where you work.

On separate occasions I have been corrected by my students, a few from the city of Griffen, GA and the surrounding areas and two from the city of Albany GA, as well as students from Macon that their number one cause of OSP outages are from cables and closures being hit by gunfire.

Of course there is also rodent chewing, e.g. squirrel chewing.

I’m forwarding a few pictures that I received this week from student and I have been promised a few pictures of splice closures that have been shot.

FOA wishes to thank Stephen Casey, CFOT, CFOS/S/T, CPCT, Telecom Tech for the City of Albany, Georgia, for these great photos.

Mark's school Brierwood Technical Institute in the Atlanta area has trained quite a few techs from Georgia. The cities in the region have built extensive fiber optic networks. The City of Albany, for example, has several diverse fiber rings covering more than 85% of the area offering all types of services and speeds. Read more about Albany' telecom services here




Did They Get It Wrong Again?

In the September FOA Newsletter last year we ran a long article about how the way almost everybody depicts the structure of optical fiber is probably the reason some people erroneously think you can strip the cladding off a fiber for splicing or termination. We think we adequately debunked that idea, but we got a comment just last month asking about stripping the cladding so our job is not completed.

Recently there were a couple of online articles claiming dB loss was a positive number and gain was a negative number. Is that right? Read on.


Optical Loss: Are You Positive It’s Positive?

A recent post on a company’s blog and article on the CI&M website discussed the topic of the polarity (meaning “+” or “-“ numbers) of measurements of optical loss, claiming loss was a positive number. The implication was that some people failed fourth grade math and did not understand positive and negative numbers. The claim is that insertion loss is always a positive number. Is that right?

Well the real problem is that to understand this you need to understand logarithms and that’s Algebra II*, way beyond fourth grade addition and subtraction. You see dB is defined as a logarithmic function:

dB equation

With logarithms, if the ratio of measured power to reference power is greater than 1, e.g. measured power is more than reference power, the log is positive. If the ratio of measured power to reference power is less than 1, e.g. measured power is more than reference power, the log is negative. If the ratio is 1, the log is 0.

Since the logarithm for optical power ratio is base 10 and then multiplied by 10, each change of 10 in the ratio of the measured and reference power becomes a change of 10dB. E.g. +10 dB is a factor of 10 (10 times log10 10 which is 1), +20dB is a factor of 100  (10 times log10 100 which is 2), +30dB a factor of 1000  (10 times log10 1000 which is 3)and so on. Negative dB means division, so -10 dB means a factor of 1/10th  (10 times log10 0.1 which is -1), -20dB a factor of 1/100th  (10 times log10 0.01 which is -2) and so on. 0 dB means the measured power to reference power ratio is 1 – they are equal.

Let’s try a graphic explanation of this equation. Take a look at this “semi-log” graph (logarithmic on the x axis and linear on the y axis) of dBm vs optical power in the range commonly used for fiber optics and calculated with our equation above. Remember 0 dBm means all power is referenced to 1 milliwatt optical power.

dB to watts

As you move to the right, power increases and the value in dBm gets more positive – that would be gain. So from 1mw to 10mw, we see a gain from 0dBm to +10dBm or 10dB, a positive change.

As you move to the left, to lower optical power, as would be loss, the dBm value gets more negative. From 1mw to 100microwatts (that’s 1/10mw), we go from 0dBm to -10dBm, or -10dB; that negative change indicating a loss of 10dB.

That shows gain is positive dB and loss is negative dB. Now we’re getting to the fourth grade math.*

How about an example? Let’s say we decide to test a singlemode cable plant. We start with a laser source and launch cable which we measure our reference level for loss with a power meter to have an output of 0dBm. That’s 1 milliwatt of power, about the normal output of a fiber optic laser. After we attach the cable plant to test and a receive cable to our power meter, we measure 3dB loss.

What power did we measure? The power must be lower, of course, since we have loss, and 3dB is approximately a factor of 2, so the power the meter measured is 1mw divided by 2 = 1/2milliwatt or 0.5mw. Since our power meter is measuring in dBm, it will read minus 3dBm (-3 dBm), since lower optical power is always more negative. If it read +3dBm, the power measured would be 2mw and that would be a gain from our reference (0dBm) which we know is incorrect – passive cable plants are not fiber amplifiers.

Here is the graphical version of this loss test:

 dB loss or gain

And then there is this short movie on the FOA Guide page explaining dB showing how a power meter shows loss when a cable is stressed to induce loss:

dB on a power meter

As the fiber is stressed, inducing loss, the power level goes from -20.0 dBm to --22.3 dBm.That's a more negative number.

No question – loss means a more negative power reading in dB and a negative number in dB indicates loss.**

But if you are a manufacturer of fiber optic test instruments that offers optical power meters and sources to test loss, why would this confuse you? 

Perhaps we should blame accounting.

Suppose you have a company that has $1million in sales and $900,000 in expenses. What’s the profit? It’s $1,000,000 - $900,000 = $100,000. That’s a profit, right?

But suppose your company has $1million in sales and $1,100,000 in expenses. What’s the bottom line? It’s $1,000,000 - $1,100,000 =  - $100,000. Wait a minute, that is a negative number – that’s not a profit, it’s a loss.

So in accounting, profits are positive numbers and losses are negative numbers when we do the math, but when we talk about loss, we don’t say we have a loss of “-$100,000,” we just have we have a loss of $100,000. Then we’ll put that number in parentheses when we publish our P&L like this ($100,000) and hope it doesn’t get noticed by investors, but you know it will.

Loss and gain in fiber optic measurements are similar. If you are using a separate source and power meter, loss will be a negative number and gain will be a positive number. But because of convention, we sometimes drop the signs when we report the values because loss always means the optical power measurement was negative and gain means the optical power measurement was positive. But maybe that’s not what the convention has evolved to.

Optical loss test sets (OLTS) aren’t designed to measure and display optical power, just loss. The actual power measured is lost in the algorithms used for calculating loss based on the “0dB” reference power and the measured loss. Long ago, most OLTS measured loss and displayed it as a negative number, but some companies who got into the fiber optic test equipment business from other test businesses arbitrarily decided to display loss as a positive number, and today most OLTS do show loss as a positive number. But when the instrument sees a gain, which it can do if improperly used, it therefore displays a negative number, which can be very confusing to a trained fiber tech who understands fiber optic power and loss measurements.

OTDRs do the same thing. I looked at traces from a half-dozen OTDRs and all showed loss as a positive number and gain as a negative number. And yes, when you have a gainer in one direction, they show it as a negative number. Telling them that is wrong will fall on deaf ears, I’m afraid.

The same article/blog post goes on to discuss optical return loss and reflectance, which has similar issues but they get it more or less right, which is confusing. Why can they understand that more negative numbers for reflectance means lower power in the reflectance but claim the opposite for insertion loss?

The “less right” is that with most OTDRs reflectance of an event and optical return loss (ORL) are not the same thing. ORL is the summation of all reflectance events and fiber backscatter from the entire length of fiber.

And, please, please stop saying “back reflection;” a reflection always goes back toward the source so the term is redundant and was dropped from fiber optics years ago.

*So the problem is not simply fourth grade math, it also involves a bit of convention and tradition and marketing. And it requires understanding logarithms that create the negative number of loss. That’s more like Algebra II or 7th grade math, and here is a good tutorial from Kahn Academy on that: https://www.khanacademy.org/math/algebra2/exponential-and-logarithmic-functions/introduction-to-logarithms/v/logarithms

And more basic, here is a tutorial on adding and subtracting negative numbers https://www.khanacademy.org/math/cc-seventh-grade-math

** If you want to calculate this yourself, FOA has a XLS spreadsheet you can download that will calculate the equations for optical power for you.

The FOA has an explanation of dB on our online Guide and a couple of graphics that illustrate what happens with loss.



There's more below....

.. plus some really interesting technical questions discussed in depth






New:

The FOA 2018 Update Page covers all the new technology and applications we covered in this newsletter in 2018. Now you can review all that new tech at once.

The FOA Fiber FAQs Page (FAQ s = frequently asked questions) gathers up questions readers have asked us (which first ran in this newsletter) and adds tech topics of general interest.

This months "Good Questions" has some unique questions including one about how fiber optic cable can catch fire from the signals it carries!


Fiber Optics For Managers

In the FOA, as part of the fiber optic industry and especially in our role as educators, most of our focus has been training the designers and installers of fiber optic cable plants and networks. But what about the people for whom they work or build the networks? What do network managers, project managers, supervisors, network owners, IT personnel, facilities managers, network designers, estimators, inspectors, etc. need to know about fiber optics to ensure the success of their project?

The responsibility for the success or failure of any project ultimately lies with the project manager. We've seen quite a few instances of fiber optic project problems caused by improper management and many of the help calls we get at FOA indicate the manager's lack of knowledge of fiber optics. Some of the problems they call us about are amazing. An IT manager for a large metropolitan area found that the cable plant he had installed didn't work because it had 4,000 bad connectors. Another sent us OTDR traces submitted by his contractor for documentation that showed only that the cables were too short to test with an OTDR. In one big project, contractors subcontracted to firms that had no fiber experience who were digging up and breaking underground utilities daily. 

These kinds of problems can be cured easily if the managers have some basic knowledge of fiber optics and the processes involved in building networks.. They do not need a typical FOA fiber optic training course because those courses are based on KSAs – the knowledge skills and abilities needed by installers - and while they need to know what skills are necessary for installers, they do not necessarily need those skills themselves . What they need is just a basic understanding of fiber optic network design, installation, testing and operation.

FOA has been working with several groups to develop educational programs for managers. We've started with a page in the FOA Guide on Fiber Optic Network Management that describes what our advisors think is important and created a page to introduce them to the language and technology of fiber optics which we call "Fiber Optic Jargon - Illustrated." Over time, we'll be expanding this section and create a Fiber U self-study course also.



Corning Trains "Warriors For Wireless" And Certifies As CFOTs, FCOS/Ws

Corning Optical Communications – Engineering Services (ES), FOA Approved School 211-01, and Warriors4Wireless (W4W) just completed the first phase of the Fiber Optic Technician, with Fiber for Wireless Emphasis, pilot program for W4W.

The scope of the program is to deliver a Fiber Optic Training and Certification Program that supports W4W’s mission of supporting US Veterans transitioning into civilian roles by preparing them for rewarding careers in telecommunication fields. W4W is led by Air Force Major General (Retired) Kevin Kennedy who also participated in the full first phase of the program.

Besides providing training and skills to enter the fiber optic craft, the program also leads towards federally and Department of Labor recognized FOA certification. The First phase concluded with a 100% passing rate in completing and achieving the FOA CFOT certification.

The pilot program, conducted at Corning’s facility in Hickory, NC, was also used for exploring integration of Learning Management System, virtual classroom tools, and interactive mobile media for pre-course training, supporting framework, coupled with guided hands-on practice, and assessment for helping participants achieve success in the program. The feedback obtained from all participants was extremely positive, which proves and confirms Corning ES’s holistic training approach as effective and successful.



Updated FOA Certifications

  We continue to expand our certification offerings, adding "Fiber For Wireless" last year, and fine-tuning our current offerings to keep up with the changes in fiber optic technology and applications. In the last year we've updated our CFOT, CPCT and CFOS/O certification programs and their FOA references online and in textbooks.

The CFOT fiber certification update includes adding more information about new technology and products like SOCs (splice-on connectors), microcables, as well as expanding the information on OSP and premises applications. The CPCT premises cable program has been updated to cover the new technology in areas like passive OLANs and data centers.

The biggest change in FOA programs was to the CFOS/O Outside Plant (OSP) Specialist program. We were asked to cover more about OSP construction so we integrated the material from the FOA OSP Construction Guide written by FOA Master Instructor Joe Botha into the course. To make room for the new material, we changed the prerequisites of the course to require a CFOT, instead of covering basic fiber tech in the OSP course.

FOA Certifications Now Last For 3-Years

Beginning in 2019, all FOA certifications issued or renewed will be for a period of 3 years. Most certification bodies worldwide have standardized on 3 year certifications. FOA has been working with a number of organizations that use our programs but have standardized on 3 year certifications. FOA has decided that it is time to change our policies to align with the majority of other organizations.

Remember that FOA certification renewals include all the certifications one individual has for one price. FOA does not charge for any additional certifications, so, for example, if a CFOT also has specialist certifications like the CFOS/T or CFOS/S, they are included at no additional cost when the basic certification is renewed.


Want To Be A Guinea Pig And Save?
As part of our program to adhere to international standards for certifying bodies and to ensure FOA certified techs are up to date on the latest technologies and applications, FOA is also considering adding a short online course based on our annual "Fiber Update" as a future requirement for renewal. This course would cover new technology and applications that FOA thinks all technicians should be familiar with. Over the next year we will be testing this concept by offering it to selected individuals. You may be one of those selected! Watch your email for your renewal notice.




Another New Book On Tech (Warning: Shameless Self-promotion)

Delusional Management book

As the author/editor of the FOA series of books, website and this newsletter, I'm kept very busy. But late last year I managed to finish my first book on high tech business called Delusional Management. It's part learning management by analyzing what others do wrong, part some history of the tech industry, including fiber optics and part memoir of 50 years in high tech. And some humor. Available on Amazon in paperback and Kindle. Jim Hayes

NearBlasting  Fiber Optic Cables

Last month we ran a Q&A question about blasting near fiber optic cables. Bill Graham, FOA Board Member and long-time instructor in Canada, tells us that he suggests a more conservative approach. This is what he has taught in his classes:

Blasting and Fiber Optic Cables

Two situations:
1.)    Aerial on poles or towers
2.)    Buried in ground

Aerial:

Blasting near fiber optic cables
Blasting close to poles with fiber optic cables can depend on the soil between the blasting area and the pole.  For example:  In parts of Ontario there are large areas of solid granite. The pole is generally bracketed to the rock. (Some areas have started drilling the rock) there is a solid connection from the blast hole to the pole, up the pole onto the bracket and to the Fiber Optic cable, which they seem to forget is glass.

Blasting near fiber optic cables

We recommend the following:
1.)    Cover the aerial cable with Big O (4” perforated drain pipe slit along the length) as shown in the photo above. This protects only from flying rock.
2.)    Removing the cable from the pole clamp and hanging it from the bracket with a  Bungie strap.

Blasting near fiber optic cables

Blasting locations are carefully engineered… however, if the crew wants to get home early on Friday and they double up on the blasting the damage risk increases substantially. ( The red cups in the photo are blast holes.) Most companies are wary  enough not to guarantee “no glass damage”. This area is almost all solid granite.

Cables Buried Underground:
Regardless of Kinder Morgan’s recommendation, I suggest 5-6 meters separation is not adequate and  should be at least 12 to 15 meters.



New Photonics Tech Training Program In New England

Photonics is a general term embracing much more than fiber optics, but covers many of the technologies involved in developing and manufacturing fiber optic components like lasers, transscivers, etc. Here is an announcement of a new college program in the New England area.
 
Stonehill College is involved in the creation of a certificate program to train photonics technicians for work in optics- and photonics-related industries. This is a collaboration between Stonehill, Bridgewater State University, and MIT.  They are sending a short survey to people in area industries to determine what their priorities are for the training of new technicians, so that they can better tailor their program to suit the needs of local employers. They would greatly appreciate it if your company would participate in the survey.

If you would like to participate, please e-mail dsimon@stonehill.edu

FOA - IMSA Partnership Adds New Training Opportunities

IMSA, the professional society of municipal traffic engineers, has partnered with FOA to offer the CFOT program to its members. IMSA is in the middle of the technology changes that are affecting cities - intelligent traffic signals, smart cities, autonomous vehicles, etc. which all depend on a robust fiber optic infrastructure. With this partnership, we have current FOA instructors teaching IMSA-FOA CFOT classes and IMSA instructors being trained to become FOA Certified Instructors. The IMSA Western Section has been active at developing instructors using some members very experienced in fiber optics like Mike Fong who works for the city of Santa Rosa, California (FOA News 8-2018) and Jose Gonzalez, an IMSA Director who works for the city of San Ramon, California, shown teaching a CFOT course in Santa Fe Springs, California in December.

This web site is to help Home Owners Associations and other small communities who are looking to build their own fiber optic network to provision gigabit Internet for their residents. It assumes that you are on your own, and no telecom carrier is interested is building out a fiber network for your area. Methods described here are applicable to communities ranging in size from a couple of hundred residents to 20,000 or more residents.

TIA Fiber Optic Tech Consortium Has New Website

TIA FOTC

The TIA FOTC, a group of TIA companies that promote fiber use, has a new website with lots of information on the organization, it's webinars and white papers. It also has a section on member news that includes new products and applications.
https://www.tiafotc.org


New Section Of The FOA Guide - The FOA Guide to OSP Construction

FOA has created a new section of the FOA Guide on OSP Construction. We've expanded some sections to include more on cable pulling, blowing and aerial construction with lashed and ADSS cables. The FOA has extensive material available in our textbooks and online FOA Guide on what is involved in the fiber installation process (cable installation, preparation, splicing, termination and testing), so consider this the textbook for the construction processes that occur before the typical FOA CFOT-certified techs begin their work.

Included in this new Guide is comprehensive information on new techniques like air-blown cables using microcables and microducts. It also covers aerial cable installation more thoroughly than is typically found in websites or literature.

The audience for this new section of the FOA Guide includes the management of organizations owning or installing fiber optic cable plants, designers or estimators of the cable plant, as well as the actual CFOT certified techs doing the installation work. It is intended to provide background information on the entire project and in conjunction with the other FOA information on basic fiber, OSP fiber, design and testing, provide complete information on all stages of a fiber optic communications project.

The FOA Guide to OSP Construction


Also new - FOA Guide section on inspecting and cleaning connectors.



New Free Fiber U Course On OSP Construction 

Now that we have the FOA Guide on OSP Construction, we can do a free Fiber U online course on the subject. The new Fiber U Course On OSP Construction includes a review of fiber optic technology for those just getting started or looking for an update, a lesson on project preparation, then covers underground construction, underground cable installation, aerial cable construction and installation, then leads you to the next steps in OSP construction, splicing, termination and testing.

This Fiber U course is aimed at managers of fiber optic projects, either with the network owner or the contractor building it, want to know how this construction is done and how it needs to be designed, estimated and construction. It is also appropriate for installers and contractors who are involved in the construction process also.

Take the free
Fiber U Course On OSP Construction here.


As we researched products and installation practices for the new OSP Construction sections, we came across some interesting products and services. See

Recycling Fiber Optic Cable

We received this note from Steve Maginnis, LD4Recycle/ CommuniCom Recycling on recycling fiber optic cable:

We have 3 Processors gearing up to accept fiber optic cable (FOC). As we all know, all FOC is not the same. Several truckloads of “typical” FOC scrap from FOC mfgrs and “typical” FOC and Coax cable have been studied and tested.

Therefore, today you can begin contacting me with the type FOC material or scrap you toss to the landfills today. We need to quantify the expected feedstock. Our expectation for quantities is quite large (tons) but there is a capacity limit. And I do have several processors that can take ALL materials and others that can accept LIMITED types of FOC material and quantity.

Safety On The Job

Safety is the most important part of any job. Installers need to understand the safety issues to be safe. An excellent guide to analyzing job hazards is from OSHA, the US Occupational Safety and Health Administration. Here is a link to their guide for job hazard analysis.

Investigators Eye Fiber Optic Work in Deadly Wisconsin Gas Explosion

Firefighter killed, nine injured, and three buildings destroyed in downtown Sun Prairie, Wis.

A hole punched into a 4-in.-dia gas pipeline during fiber-optic line laying is blamed for an explosion that killed a 34-year-old fire captain and injured nine other people, including four firefighters, in downtown Sun Prairie, Wis., on July 10. The injured were treated at nearby hospitals and have since been released. The blast destroyed three buildings, including the Barr House, a tavern at 100 Main St. that was owned by the deceased fire captain, Cory Barr.

Sun Prairie Fire Chief Chris Garrison said at a news conference that after the leak was initially reported at 6:20 PM CDT, first responders established a 300-ft-dia "hot zone" in the area and evacuated about 65 people before the explosion occurred. "The rapid response of firefighters, EMS and police saved a lot of lives," Garrison said. "This could have been a lot more tragic than it was."

The owner of the fiber-optics network is Verizon Wireless, which confirmed in a statement that it had contracted with Bear Communications "to provide a fiber backhaul for our networks." It added that no Verizon employees were present at the job site. "Verizon does contract with local providers in various markets to provide fiber backhaul for our networks," the Verizon statement said. "While we have not been contacted about the investigation, both we and Bear are prepared to work with law enforcement, public safety and public officials as they investigate this tragic situation."

Read the story in ENR. And the final report by the NTSB details the mistakes made by the contractor.

FOA also has lots of information on safety: FOA Guide, YouTube video and a Safety Poster

Another Source Of Articles On Fiber

FOA President and editor of this newsletter Jim Hayes has also been writing a column in Electrical Contractor Magazine for more than 15 years now. Electrical contractors do lots of fiber work and this column has covered some toics they are interested in including installation processes, network design, fiber applications and in the last year, a lengthy series on dark fiber - what it is, how's its used and how it benefits the growth of communication. A recent web site redesign makes it easier to browse all these articles - just go to http://www.ecmag.com/contributing-authors/jim-hayes and you can see all of them.




Fiber Optic Education For Students At Any Age 

We hear about fiber optics all the time - it's in the news whenever we hear articles about high tech, the Internet and communications, and many communities are getting "fiber to the home." But few people really understand fiber optics or how it works. FOA is focused on educating the workforce that installs and operates these fiber optic networks but we're always getting inquiries from STEM (science, technology, engineering and math) teachers who want to introduce fiber optics to younger students in K-12 grades or technical schools.

We start with the FOA Careers In Fiber Optics Video on YouTube and visit the FOA Careers In Fiber Optics web page at www.foa.org/careers/. These are for students who think they might be interested in careers in fiber optics and want to know more about what fiber techs do.

Teachers for fiber optics
Using red laser light (a VFL here but a laser pointer works also) to show how fiber guides light.

FOA has begun developing a series of YouTube videos intended for teaching students in elementary, middle and high schools about fiber optics. The first FOA video is titled "Fiber Optics For Teachers." With this video, we show teachers how fiber works and carries signals and then explains simple experiments to demonstrate how fiber optics works in the classroom using some plastic fiber and a laser pointer. Since many teachers do not know where to get the fiber, the FOA offers to send them a sample for use in demonstrations in their classroom (USA only right now.)

At the end of the video, teachers are given directions on how to request samples of the plastic fiber from the FOA.

This video joins the "Fiber Optics Live" series How Light Travels In A FiberFiber Attenuation and Connector Loss that show how fiber works using simple experiments that can be duplicated in any classroom. More videos will be coming soon.

If you have kids or know some teachers who would be interested, please send them to the introductory video Fiber Optics For Teachers  and we'll be glad to help them get started with some entertaining programs for their classrooms.


Resources For Teachers In K-12 And Technical Schools

Teachers in all grades can introduce their students to fiber optic technology with some simple demonstrations. FOA has created a page for STEM or STEAM (science, technology, engineering, arts and math) teachers with materials appropriate to their classes. Fiber Optic Resources For Teachers.

 

If you have kids in school or know teachers who are interested, send them to the FOA page Fiber Optic Resources For Teachers.






Should Your Company Become An FOA Corporate Member?

As all FOA individual members know, they join the FOA by becoming certified, mostly taking their CFOTs but some CPCTs,  either by attending a FOA approved school or joining directly based on field experience (our "work to cert" program.) Over the years, we've been contacted by manufacturers, contractors, consultants, and other types of organizations who ask about becoming members.

We don't certify companies or organizations, we told them, so we were not sure what we could offer as a benefit of membership. But then, companies asked about using our educational programs to train employees, how they could get listed on the FOA website as service providers or if they could get a quantity discount on membership or certification for all the FOA members working for them. That began to sound like a benefit for being an FOA corporate member. And providing a list of useful suppliers to the market could be a benefit to the industry as a whole.

So FOA has quietly been letting companies and other organizations join the FOA to take advantage of those benefits so we now have several hundred corporate members. We've put then into a database and listed them on the FOA website in map and list form. Here's the map.

FOA Corporate members

The online
map and list can be used to find suppliers and service providers.

The map, like our map of schools, lets you find the FOA corporate members close to you.  The table form lists them by category: Installer/Contractor, Component Manufacturer, Installation Equip. Manufacturer, Transmission Equipment, Services/Consulting, Distribution and Users of Fiber Optic Networks. You can sort the tables to find members meeting your needs, e.g. by location, certifications offered, etc. Click on any column heading to sort that column; click twice to sort in reverse order.

How Does An Organization Become An FOA Corporate Member?

Simple, just fill in the online application form. When your application is accepted, you will be asked to pay the one time membership fee - $100US. You will then be listed on the online  map and list, have access to exclusive FOA educational materials for your employees and get discounts on certifications and renewals.

Lennie & Uncle Ted Guides - Perfect For Getting Started

Lennie and Uncle Ted's Guides have moved  to the FOA website. Lennie is the place where many if not most fiber techs begin their education. FOA has just updated the two guides to ensure they stay relevant - more than 20 years after they were first written.

Lennie goes all the way back to 1993 when he was created as the mascot of the original "Fiber U" conference - the same Fiber U that is now the FOA's web-based training site. Lennie Lightwave's Guide To Fiber Optics was created as a beginner's introduction to fiber optics. Over 60,000 printed version of Lennie's Guide were given away and it became one of the first commercial web pages in 1994. Uncle Ted's Guide To Communications Cabling was written a few years later to introduce techs to "Cat 5" - UTP wiring - that had only recently been standardized in TIA-568.

Lennie and Ted's Guides are used in the current Fiber U online self-study programs and are still the best place to start learning about fiber optics.


Lennie and Uncle Ted's Guides are online at the links here, can be downloaded as printable PDFs and are now also available as free iBooks on iTunes.

Lennie Lightwave's Guide To Fiber Optics   Uncle Ted's Guide to Premises Cablling

Lennie Lightwave's Guide to Fiber Optics and Uncle Ted's Guide To Communications Cabling   are now available free to iPad users who can download them from the Apple iTunes store. Of course they are still available online or for download.

FOA iPad Apps

FOA LossCalc
FOA Loss Calculator AppFOA LossCalc estimates the optical loss of a fiber optic link. This will save time for the installer of a fiber optic link needing to know whether test results are reasonable and/or make a "pass/fail" determination. It can also help the designer of a link to determine if communications equipment will operate over this link.
By choosing the type of link (singlemode or multimode) and specifying the length of the fiber and numbers of connections and splices, it will calculate the end to end loss of the link. The app has default specifications for singlemode and multimode links or the user may create custom setups with specifications appropriate for any application. http://itunes.apple.com/us/app/foa-losscalc/id476262894?mt=8&ls=1

Feedback

We always enjoy feedback, especially when it shows how great some FOA instructors are. These came from students of Tom Rauch, an instructor at BDI Datalynk:


"I took your fiber optics certification courses this past March. I just wanted to let you know that in two weeks I start working as a fiber optic technician with ___ up in ___. You mentioned on the first day of the course that there is always one guy in class who had rubbed his last two nickels together to be there and, in that instance, I was that guy. Now I'm going to be able to provide for my family like never before and I owe it to the certification that I received from you and BDI Datalynk. I just wanted to thank you again."

"Thanks to our tremendously knowledgeable and patient instructor Thomas Rauch, who was not only generous in sharing his wealth of information, but he did so with ease, humor and in a way that invited curiosity and participation. He was encouraging and proud of our accomplishments and helped us learn from our mistakes in a way that did not break our confidence, rather it pushed us to better results the next go around. The hands on labs were just AWESOME!" Just thought you should know what a class act you have representing you in his travels..... but then again you probably already knew that! : )

In almost 19 years at Verizon and having held numerous positions, I have gone through many training sessions. I cannot remember ever having been actually looking forward to coming back to class quickly after lunch, to get back to the hands on activities, and walking away with the sense of empowerment that the information presented was not only relevant but dead on point accurate! I will be signing up for the Outside Plant class on March! I can't say enough good things about Tom and his impact! Feel free to quote me, I can only imagine that he will open so many doors and change so many lives in the years to come, with his style of teaching! Great experience, awesome job!

Q: Our city is installing a 1.5 mile run, mostly aerial and we want to use ADSS cable. There are two or three road crossings where we want to go underground in conduit installed by directional boring. Can the ADSS cable be dead-ended, brought to the ground, figure-8ed and pulled through conduit then continue the aerial installation?
A: The answer is yes this is not an issue and is done all the time. It is standard procedure. (Thanks to Pat Dobbins, FOA, the expert on ADSS cables.)

Q: I recently read an article you wrote in April of last year about micro trenching..Currently, I am employed with an underground construction company. Something we have never been involved with is micro trenching and would like to possibly get some equipment and training scheduled in the near future. In saying that, it has seemed to be almost impossible to find numbers on the price per foot. Essentially, I am asking if you have any resources to some up with those numbers or models to maybe use for pricing purposes.

A: Microtrenching is becoming another tool that contractors are adopting because like directional boring is is less disruptive than regular underground construction. I’m working with one group that’s using microtrenching in CA cities, installing microducts and a 288 fiber   about the size of a #2 pencil. Cost is difficult to generalize other than “more than aerial and less than trenching.” Cost is very dependent on  where you are working and what the local geography looks like. We know one contractor who claimed to do 5 miles a day in rural Washington at costs near that of aerial. It’s especially good in areas with lots of base stone where trenching or boring is near impossible or cluttered utilities downtown.

Here are a couple of pages on the FOA website about microtrenching:

Underground Cable Construction
Microtrenching

Ditch Witch sells equipment for trenching and trains users. Condux has the equipment for blown cable and offers training several times a year.

Old Multimode Fiber
Q:
We have old multimode fiber and we are still connecting more equipment to it over greater distances and need some way to insure the equipment will work.
A: I do not know of any simple formula for figuring this out. Last time I remember such a formula from around 2000 done for Gigabit Ethernet with VCSELs and the equation reminded me of the quantum mechanics course I took in physics. The problem is you have two bandwidth factors, modal dispersion and chromatic dispersion. Modal dispersion is highly dependent on mode fill, e.g. the metric “encircled flux” was developed to define the mode fill of multimode fiber with VCSEL sources for simulations to estimate bandwidth. Chromatic dispersion is dependent on the fiber spec and the spectral width of the source which is better with lasers and LEDs.

What generally happens is the standards group developing the network standard, especially IEEE 802.3 for Ethernet, runs the numbers and specifies a maximum distance for the particular network and its speed. FOA has a table of these specs here: Specifications for fiber optic links and systems, including FTTx


Can A Fiber Optic Cable
Catch "Fire"
Q: While working on a cut-over of a dwdm circuit something has happened that I am now looking for an explanation. A transmission fiber emitted "fire" on that same fiber! We did not see any optical light we saw fire. About 5 cm of fiber burned and remained smoke. What phenomenon occurred? Are the dwdm amplifiers so powerful enough to generate fire? Unfortunately I could not get into the station to take the model of the equipment.
A: We’ve heard of high power WDM systems exploding dirt of the endface of fiber connectors and damaging them, but this is a new one. We contacted several technical people in fiber companies and found that this can happen if there was a crack in the fiber in the cable near the connector or lots of reflection perhaps caused by a very dirty connector that allowed the very high power to heat the cable enough for combustion. DWDM with many multiplexed signals and a fiber amplifier creates a lot of power confined to a very small core of the singlemode fiber. That power can ignite the acrylate coating on the fiber.

Installing ADSS Cable Underground
Q:
I'm installing an aerial run of ADSS cable and wonder if I can pull the cable under roads in duct installed by directional boring without splicing when I need to go underground.
A: Yes you can pull ADSS cable in ducts installed by directional boring without splicing. Just install the ADSS cable link to the pole where you need to go underground and "dead end" it at that pole. Drop the cable down, "figure-8" the cable to prepare for the pull, then pull the cable in the duct. If you go aerial on the other side, just continue the ADSS installation procedures.

Reflective Events Causing Transmission Problems
Q:
I have a technical question about reflective events. I recently assisted to troubleshoot an intermittent SM fiber link for a customer. The cable was dug up a few years ago and a fiber contractor has (fusion spiced) a different chunk of cable into the link to repair it. When troubleshooting the link, I checked the cable with the otdr. I found that each of the 12 fibers had a reflective event at the fusion splice. This was only at the splice tube closest to me. The other fusion splices in the other tube were virtually invisible (as they should be). I'm a little puzzled as to why there are reflections at the fusion splices. I did a little research, but couldn't come up with a good answer as to what is a possible cause of the reflections. (The OTDR also showed a lot of ghosting on every fiber tested) (in some cases it recorded over 40 ghost events) Although I haven't been able to confirm that there is high Bit error rate due to the transceiver not providing these statistics, (except for 3 out of 10 pings fail) I am suspecting that High reflectance is possibly the cause of their unreliable fiber link.
A: Reflectance is a big problem in SM links, especially short links. If you are seeing lots of ghosts, I suspect the link is very short. Fusion splices can have reflectance if the splicer is improperly set and the fusion is incomplete or has bubbles. Those splices should have not only have reflectance but higher loss. The solution is to open up the closure, use a VFL to find the reflective events and redo the splices.

Blasting Near Fiber Optic Cables
Q:
We have a project where blasting is planned near fiber optic cables. We find no standards for this. Is it safe for the fiber or should we treat it like other utilities like gas and water?
A: FOA recommends considering fiber optic cables to be similar to gas lines when blasting nearby. We know of no standards for this but there are some descriptions of projects requiring blasting near fiber optic cable installations. Here is a pipeline company's guidelines for blasting. The guidelines seems to focus on staying 5m from the fiber optic cable and using careful blasting techniques.


Cleaning Connector Protective Caps
Q:
How do you clean LC Fiber Optic end caps (the cap that covers the cleaned fiber cable)? Is there a tool for that?
A: We assume you are talking about the small plastic protective caps on the connector ferrule. There is a joke in the industry that goes “there’s a reason they call them "dust caps’” they’re often full of dust.” The problem is these are plastic molded parts that are made by the billions for various purposes - some just fit fiber optic connectors. They come out of the molding machine and are dumped in barrels. No provision is made to keep them clean, plus they will have some mold release chemicals inside them that can attract or hold dust. Even static electricity is a problem.
We know no way to clean them nor to keep them clean. We recommend using them to protect the connector ferrule - in fact we’re trying to get people to call them “protective caps” - but after they are removed and before use (connecting to another cable or a transceiver or testing them) they need inspection and cleaning.
See these pages in the FOA Guide: Microscope Inspection And Cleaning of Fiber Optic Connectors  Cleaning Fiber Optic Connections

Directional Splice Loss
Q: I have a customer that is splicing a fiber distribution hub to their fiber plant.  The fiber distribution hub utilizes 100FT long fiber stubs of SMF G.657.A1 and the fiber plant uses SMF G.654.D.  The project has a contract fusion splice passing spec of 0.2dB loss, averaged bi-directional and also a one-way <0.3dB loss (either direction) specification; using an OTDR for measurements.
From my research, if the splices OTDR’s test results for the 2 directions are -0.2dB / +0.6 (average of +0.2), the network is not actually seeing a +0.6dB loss; but this is how the OTDR interprets the backscatter information… the OTDR being somewhat confused due to the bend insensitive fiber characteristics.
A: Correct - the directional differences are due to the mode field diameter variations in the two fibers.  G.654 is a large MFD fiber, ~12.5microns, compared to ~9 microns for G.657.A fiber. The OTDR measures based on backscatter which will be very different for the two fibers.

Markers For Underground Fiber Optic Cables
Q:
I have a general question about above ground markers for fiber optic cable in conduit.  Is there a recommended spacing for the markers?  Is there a standard to reference for this?
A: We asked some people who make them and they said the guideline is “line of sight.”  The rules for markers are mainly what information needs to be on them. Of course we also recommend adding marker tape about a foot above the conduit. I was curious if there were any legal issues and I found this interesting page from Cornell Law School:  https://www.law.cornell.edu/cfr/text/49/192.707
So I might  add to line of sight any crossings of roadways, rail ways and some markers for bridge crossings.
We have a new section on the FOA Guide: Outside Plant Fiber Optic Cable Plant Construction that may be useful.

Reflectance And Return Loss
Q: Help me understand measuring reflection little better. Why do we consider -55dB to be a better reading than, say, -25dB? If reflection and return loss are inverse readings and we had a 55dB return loss, would that positive reading for return loss be considered good?
A: Reflectance is measured as the ratio of reflected to incoming signal at a connection. The confusion comes because reflectance and return loss are inverse readings. Consider this:
If we have 1/1000 of the light reflected, the reflectance would be -30 dB (1/1000 = -30 dB) but the return loss would be 30dB since it is defined as 1000/1, the inverse, and is described as +30 dB.
Likewise, an APC connector would have a reflectance of -50 dB or a return loss of 50 dB.
However, return loss as tested by all OTDRs is not be the reflection from a single event but the total of all reflectance events plus total backscatter from the length of fiber being tested in the trace.
This is where most people are confused and misuse the terms.

Older questions are now available here on the FOA Guide.

Older Fiber, Do You Know How Good It Is?

There's millions of miles of long distance fiber installed around the world and most of it likely to see an upgrade of the systems operating on it, probably in the near future. Twenty years ago, most of it was probably running at ~1Gb/s, ten years ago it was probably 2.5 Gb/s, recently it was likely to be 10Gb/s but now many are being considered for 100Gb/s or beyond. Can the fiber support such speeds? Can it be "repaired" or "modified" to make it possible to use it at higher speeds? If you own that fiber, can you say what it is worth without knowing its future upgrade capability.

In order to know the potential for upgrades on your cable plant, you need to test it. This process involves a number of tests and is called "fiber characterization." Greg Stearns of TTP-US, an FOA Corporate Member, performs these tests and has written a short article on why you need to characterize fiber and how its done. Read about fiber characterization from someone who does it often and can explain it well.

Where In The US Do Contractors Need Licenses For Fiber Optics?

We often get asked where in the US do contractors doing fiber optic installations need licenses. We found a good website for that information, the NECA -NEIS website. You might remember NECA-EIS, as they are the partner with the FOA in the NECA/FOA 301 Fiber Optic Installation Standard. NECA is the National Electrical Contractors Association and NEIS stands for National Electrical Installation Standards. They have a very easy to use map and table that gives you data on every state in the US, so mark these pages for future reference.

Benchmarking Fusion Splicing And Selecting Singlemode Fiber
We've been asked many times "How long does it take to splice a cable?" It's not a simple answer as it varies with the number of fibers in the cable and the work setup, including whether one or two techs are working at a job site. FOA Master Instructor Joe Botha of Triple Play in South Africa did his own analysis based on decades of experience both splicing cables and teaching others how to do it properly. This is one of the best analyses we have seen because Joe includes prep times as well as splicing times and differentiates between one tech and two techs working together. He adds some other tips on fusion splicing too. This should be mandatory reading for every tech and given to every student! Here is Joe's splicing analysis. 

Joe also has an excellent writeup on how to choose singlemode fiber that helps understanding the different types of G.6xx fiber. Read it here.
And you will want to read Joe's report on splicing different types of SM fiber, including bend-insensitive (G.657) fiber. Read it here.

A Fiber Optic Tester In Your Pocket?  (See the video on Corning on YouTube )
Yes! The camera in your old cell phone is sensitive to infrared light - lots more than your eye - and can detect light in an optical fiber or from a transmitter.  Chris Hillyer,CFOT/CFOS/I, Master Instructor, Northern California Sound & Communication JATC brought this to our attention.
IR Viewer 850 nm  IR Viewer 1300 nm

If you have an old cell phone, try it. Our experience is that older cell phone cameras have better sensitivity at IR wavelengths than newer phones, so you may want to toss that old flip phone into the toolbox.

YOKOGAWA OTDR Has Extended range, High Resolution And Multitasking


Yokogawa OTDR

One OTDR manufacturer you don't hear as much about is YOKOGAWA (formerly ANDO) which is too bad - they make some of the best OTDRs, exemplified by this new model AQ7280. Need long range - how about 50dB. High resolution - 0.6m dead zone. Like touch screens, but for some functions want hard buttons, it's got that. Options for VFL, microscope, light source and power meter, etc. - it has that too.
But the unique aspect of the YOKOGAWA AQ7280 is it offers multitasking - you can let do a trace with long averages while you inspect connectors, make power readings, use the VFL or other functions.
More info on the YOKOGAWA AQ7280.

Where Are The Jobs In Fiber Optics?

Fiber Optic Installation Banner

The FOA was chartered to "promote professionalism in fiber optics through education, certification and standards." Our focus on creating a professional workforce to properly design, install, maintain and repair communications network infrastructure has led us to work with groups in many different areas of technology that use fiber optics, way beyond the basic telecom applications that most of us think of first. FOA has probably worked with most of the potential applications of fiber optics, but we're always learning about new ones!
In addition, we get lots of calls and emails from our members looking for information about where the jobs are and how to train for them. FOA has created three ways to help you find jobs, train for them and apply for them.

Where Are The Jobs In Fiber Optics?
FOA has created a 20 minute YouTube video that talks about all the applications for fiber optics, what jobs are involved and the qualifications for the workers in the field. Besides telecom and the Internet, we cover wireless, cable TV, energy, LANs, security, etc. etc. etc. It's a quick way to get an overview of the fiber optic marketplace and we give you an idea of where the opportunities are today.
