Instructor Alex Book shows students the techniques needed to master skills in one of the hands-on labs. The class included a complete FOA curriculum including hands-on labs and students took the FOA CFOT and CPCT exams.

This program was widely covered by the press because of its importance.

KTBS said: "When the group reenters society, they'll have some valuable skills to help people gain access to internet. They learned all about fiber optic cable through Bossier Parish Community College. It comes at a time when there are thousands of jobs available in the field."

"It was beautiful just coming in here every day and just being around positive people and just getting away from the other side of the jail and just learning something new," said Derrick Clark, a graduate.

The Caddo Parish Sheriff's Office noted: "The program teaches about applications, installations, and communication systems related to fiber optics through classroom lectures and hands-on lab exercises. This will give the inmates a head start if they enter the in-demand career field."

The Caddo Parish Sheriff's Office will continue offering the program to Department of Correction inmates, making it the first ongoing fiber optics program offered in a correctional facility nationwide.

POF, The Other Fiber

Practically everyone in "fiber" optics has been asked if they follow a "high fiber diet" or work in the clothing industry, fibers much better known to most people. We've all learned to patiently explain that it's not that fiber but a highly technical fiber made of hair-thin glass.

But sometimes we forget that there is another fiber used in communications, plastic optical fiber or POF. In fact POF is about as old as glass fiber and has probably gone through as much R&D trying to compete with glass fiber. Today POF has two main uses, short, inexpensive links primarily for consumer electronics and lighting.

We were reminded about POF recently by an email from one of its developers, Dr. Franz A. Salamon, while he was at DuPont. So we thought now was a good time to do a review of POF for our readers.

POF is typically a large core fiber with a thin cladding that can be made by extruding plastics, a simpler process than the preform and pulling processes used by typical glass fibers. It is usually also a step index fiber with high NA (numerical aperture or angle of coupled light) which means it gathers light well from larger sources like LEDs and produces an output suitable for lighting.

Plastic optical fiber
The plastic material in the core of POF has high attenuation and the step index profile and high NA limits the bandwidth of POF. Together they limit the speed and distance possible for digital signals, making POF impractical for many data applications. But it's low cost, easy termination (use a razor blade) and inexpensive transmitters and receivers make it ideal for many consumer applications.

If you have consumer audio equipment or a modern TV, it likely has a digital optical port that uses POF. The fact that these links so widely used indicates how inexpensive a POF link can be.

digital audio port

POF is popular as digital links in industrial machinery like robots where distances are short and speeeds are low. Its flexibility is also good for applications like robotic arms used in assembly.

POF is also used in automotive applications. MOST is a standard widely used for high bandwidth automotive multimedia applications and Flexray is used in critical timing applications like airbag deployment.

But the majority of applications for POF are lighting. It can be used to remotely illuminate objects that are sensitive to strong light or heat from traditional light sources, making it popular for museum lighting of small delicate objects. POF is also popular for lighting in areas that are electrically dangerous like swimming pools. Another popular application is creating starfield ceilings.

POF lighting

Another use is for signs or even animating an exhibit. The map below depicts a battlefield with fiber illustrating the movements of the troops.

fiber map

The applications for POF have always been limited by its limited bandwidth and distance capability. POF developers have tried to get better bandwidth and distance capability for data applications, even developing a graded index POF like multimode graded index glass fiber, but have had limited success.

FOA likes using POF to demonstrate how optical fiber works. We provide samples and directions for K-12 STEM teachers (STEM = science, technology, electronics, mathematics) for classroom demos to teach students about optical fiber.

POF demo
A VFL and POF makes a good demonstration of fiber optic communications.

We were reminded about optical fiber when a reader of the FOA Newsletter,
Dr. Franz A. Salamon contacted us about his work developing POF. He worked at Du Pont for almost 30 years, retiring in 1990. Dr. Salamon  led the team that invented PMMA (polymethyl methacryate) POF which Du Pont introduced, trademarked as CROFON, in 1965.

Dr. Salaomon's lab

He told FOA: I was the head of our team in 1966 in Wilmington, DE, which invented, created the CROFON® (Du Pont’s registered trademark) Fiber Optic from acrylic and PE. When I had the first sample in my hands, which worked, our team surrounded me and asked: what do you want to do with this? I said: "I don’t have a F…g idea. Wait and see."

Dr. Salamon worked for Du Pont in Switzerland toward the end of his career and retired in 1990. Among the other inventions his group produced was something many people have used - Teflon plumbing tape.

As we corresponded recently about his work developing POF, he was emailing with FOA from his holiday skiing in Leukerbad, Switzerland. Impressive for a nonagenarian (Franz is in his 90s!.)

Snakes On The Plains* 

Fiber techs often face hazards in their work, from weather, working at heights, near high voltage lines, even working near traffic. But there can be other hazards when working in manholes and handholes as you can see from these photos contributed by Eric Pearson of Pearson Technologies.

Snakes

In this manhole near a cornfield in Iowa, the tech found snakes living in the nice warm environment of hte manhole.


snakes

The manhole provided some nice places to curl up or hide.

A whole family was nesting in one manhole.

Most snakes are not harmful; in fact they are good at controlling the rodents who often get into manholes and chew on the fiber optic cables. But they can be a nuisance when you are trying to get work done around them.\

*Title lifted from the movie "Snakes on A Plane"  with Samuel L. Jackson about a FBI agent on a plane full of deadly venomous snakes, deliberately released to kill a witness being flown from Honolulu to Los Angeles to testify against a mob boss.



Latest FOA Book: Fiber Broadband (Paperback and Kindle)

FOA Guide To Fiber BroadbandHow does broadband work? Without fiber optics it would not work. This book is not the typical FOA technical textbook - it is written for anyone who wants to understand fiber broadband or fiber optics or the Internet. It's also aimed at STEM teachers who want to include communications technology in their classes. This book will try to explain not only how fiber broadband works, but how it was developed. It is intended to be an introduction to communications technology appropriate for a communications course at almost any level (junior high, high school or college,) for managers involved with broadband projects, or for anyone who just wonders how all this stuff works.

New Fiber U MiniCourse - Fiber Optic Project Management

Fiber optic porject managementManaging a fiber optic project can be the easiest part of the installation if the design and planning have been done thoroughly and properly, or, if not, it can be the the hardest. It's certainly important to understand what managing a project entails. This new Fiber U MiniCourse starts by defining a fiber optic project then explains what's involved in managing it from concept to operation.

As usual with Fiber U online learning courses, the course is free and like the Fiber U FTTH course, the
Fiber U Certificate of Completion is free also.

With so many new fiber optic projects starting up and so many new managers, FOA decided this MiniCourse should also offer the Fiber U Certificate of Completion free.

Woods Hole Oceanographic Institution releases rare video footage from the first submersible dives to RMS Titanic

It was 38 years ago when Woods Hole Oceanographic Institution announced that it had discovered the wreck of the Titanic, the famous ship that sank in the Atlantic in April 0f 1912. On September 1, 1985, a team from Woods Hole Oceanographic Institution (WHOI) led by Dr. Robert Ballard in partnership with Institut français de recherche pour l’exploitation de la mer (IFREMER) discovered the final resting place of the ship.

In July 1986, nine months after the discovery, a team from WHOI returned to the wreck site, this time using three-person research submersible Alvin and the newly developed remotely operated vehicle Jason Jr. The trip marked the first time that humans laid eyes on the vessel since its ill-fated voyage in 1912.

WHOI-Titanic
Newly released footage from WHOI discovery of the Titanic

You probably know why this story is important to fiber optics - the discovery of the Titanic and these pictures were made by a remote tethered vehicle Jason in one of the earliest uses of fiber optics in underwater remote operated vehicles (ROVs). Today, fiber optic tethers are widely used for undersea exploration around the world.

The videos are fascinating to watch - remember the camera is at a depth of 12,500 feet (3800 meters).

TIA BEAD Success Summit

TIA BEAD Conference

The US government's BEAD program has created plenty of speculation about what it means and how it will be implemented, not to mention a lot of hard selling of products and services that might be involved. If you are tired of the speculation and sales pitches, this might be the conference for you.

TIA, of course, is best known for it's work in standards, but its location in Washington, D.C. and connections into the various federal agencies and Congress gives it unique insight into the progress of the IIJA/BEAD programs. And a lot of what has been said over the last year is speculation as the actual programs take shape, so now is a much better time to get a more down-to-earth viewpoint on the programs.

In addition TIA has a unique focus on supply chain issues, cyber security and privacy, important areas of concern in broadband networks that should be of interest to those planning or operating broadband networks.

The timing of this conference could be good for getting updated on the BEAD program, since all states have received their initial BEAD planning funds but the next steps depend on the FCC broadband availability maps. They were released late last year, but we hear that number of comments on the maps is in the hundreds of thousands.

FOA is a TIA Member, so TIA will offer member discounted pricing to FOA certified techs, schools and corporate members. Use the FOA discount code "2023FOA" when registering.

Looking for a good online fiber optic course? The FiberWizards Essentials - CFOT Prep Course could be a solution


How do you get new hires up to speed quickly? Continue training current employees and prepare them for the certification your customers are requiring? OJT - On-The-Job-Training. - is the usual answer, but an OJT program like the FOA's OJT-To-Cert program - requires a commitment from experienced techs and supervisors to ensure the techs stay on course.

FiberWizards Fiber Optic Technician OJT Course

FOA Master Instructor and Director Jerry Morla has a solution that can work for most companies, the "FiberWizards Essentials - CFOT Prep Course."  Students will get lots of flexibility to learn on their own terms with a very tailored and personalized experience including one-on-one coaching, virtual presentations, online modules, and access to a private Slack channel for support.

Students will get a lab kit when they join, to explore behaviors of light in fiber on their own. If the students need equipment to complete the hands-on part of the course, FiberWizards  offers rentals of equipment and consumables kits for students within the Continental US.

For companies who need to train their fiber techs but lack the time commitment needed from their top techs, which is practically all of them, the FiberWizards course could be a very good - and cost effective - solution.

Fiber Optic Design Certification For Traffic Engineers

IMSA, the professional society of traffic engineers, is now offering a certification course in fiber optic network design for the new IMSA/FOA CFOS/D certification. Based on the FOA CFOS/D, it is another certification program from the cooperation between IMSA and FOA. IMSA has been offering the IMSA/FOA CFOT basic fiber optic certification since 2017. The new certification is aimed at engineers in municipalities and transportation departments who are responsible for designing the fiber optic networks CFOTs install.

"Working with the Fiber Optic Association, Inc., we have built this new certification to go beyond the initial Certified Fiber Optic Technician, which covers the basic installation of ITS, Traffic, Fire Alarm and Communications systems. The new fiber optics design class will improve skill sets and certify that recipients are now qualified to design fiber optic systems."

"Certified Fiber Optic Specialist/Design delivers on our promise to offer tests that reflect the kinds of advanced technology our members encounter every day,” said IMSA Board of Directors President Kevin Musick.

Yokogawa System Uses Fiber For Heat Detection

Yokogawa, a company fiber techs knows best for their fiber optic test instruments and as a supporter of the FOA, also makes a broad range of industrial instruments and controls. A recent newsletter announced a new fiber optic product for detecting heat in an industrial environment.  The system uses a special fiber optic cable that can be kilometers long to sense temperature and generate alarms when abnormal conditions exist.

More Bandwidth From Every Fiber - Another Option

The continual development of optical fiber is generally based on how to get more information down the fiber and send it further. We have seen lots of options, beginning with the most basic of increasing the signal bit rate, which involves developing lasers that can be modulated at higher rates or switching to multilevel protocols like PAM4. Another option is external modulation and coherent transmission, the most successful technology now in use.

Wavelength division multiplexing (WDM) allows sending multiple signals down the same fiber at different wavelengths, which has become very common for increasing the bandwidth of installed fiber.

Other proposals include "space division multiplexing" or sending multiple signals down a fiber in different paths. It has been done with multimode fiber by carefully launching different modes into the fiber and separating them at the other end. with some success

Another version adds more cores to an individual fiber. In a singlemode fiber, the fiber diameter is 125 microns but the core is under 10 microns, so there is space in the fiber for more cores. Some fibers like this have been made and recent test show their potential.

4-core fiber
Fiber with 4 singlemode cores Drawings from the technical article referenced below.

The fiber uses 4 conventional step index singlemode cores in a 125 micron fiber. Crosstalk is a problem when cores are too close and crosstalk is higher at long wavelengths, limiting the wavelength capability. The fabrication of cores with an index trench is difficult, limiting the number of fibers and wavelength capability of the fiber. The "marker" noted in the diagram is used to align the cores for fusion splicing, another concern with multicore fibers.

To show the potential of the multicore fiber concept, a microcable with 288 fibers - 1152 cores - with  800m metro network was installed in underground conduit as shown below. To connect the multicore fiber to conventional transceivers requires splicing breakouts on to each end of the cable.

multicore fiber netowrk

The experiment was successful, demonstrating the potential of multicore fibers. One should read the entire article carefully however, as there are still challenges to using multicore fiber in routine network installations.

Managing Fiber Optic Projects - The Gantt Chart

(With An Excel File To Make Your Own)

The most common way to track projects is the Gantt Chart, a chart of activities that tracks the progress of projects along a timeline. each activity is represented by a bar and the position and length of the bar represents the starting date and duration of the activity. This allows you to see what activities are needed for the project, when the activities start and end so it can be used to track the progress of the project visually. Here is what a Gantt Chart for a fiber project might look like:

Fiber Optic Gantt Chart

You might remember an article in the FOA Newsletter in April 2022 or the FOA Guide page on Project Management about the timing of a fiber optic project where we showed the progression of steps in a project like this:


The Gantt Chart above is simply this list converted to a Gantt Chart using a Microsoft Excel spreadsheet. You can download a copy of the FOA Gantt Chart spreadsheet (xlsx file - 16kB) and use it to create your own Gantt Chart for any project. All you have to do is to input your own data and change the activity names as necessary. You can also follow the directions from Microsoft to create your own version.

Warning For Techs Doing OSP Restoration

Warning

FOA received an inquiry about whether techs working on restoring OSP links should be concerned about eye safety if the link used fiber amplifiers. To answer this question, we had to do some research on fiber amplifiers. The short answer is YES, you should be concerned. The long answer is more technical and includes details that every OSP tech needs to know.

Fiber Optic Network Maintenance
Q:
I am in the middle of building a set of documents for Fiber Optic Internet Services and one of the areas needed is a template for supporting the outside plant facilities. Might there be a template of must-haves for any service provider or municipality to have as part of their maintenance agreements once the network build and construction is finished?
A:
That’s a good topic to cover in agreements. When people ask us what maintenance fiber optic networks need, we usually tell them “build it, lock it up and forget it.” In other words what some people have suggested for maintenance for fiber optic networks, like periodic testing or cleaning of connectors, is more likely to cause damage than help. Preparing for restoration, however, is vitally important. Every day several fiber optic cables are cut by other construction.

Converting RF To Fiber
Q:
I would like to convert our SATCOM System to RFoF.  Currently we use our antenna to receive from 2 RF ports on the antenna, DC-6Ghz, and 6-20Ghz.  We also have other antennas that are configured to do DC - 1Ghz, and 1-Ghz.  Currently we are doing testing with an RfOptic RFoF converter on the 1-6Ghz with great results.  Currently we are just doing lab testing as our operational systems are all RF with COAX.
A:
Converting from coax to fiber is generally easy because the application is widespread and components easy to get. The model for what you are doing might be the Fiber to the Antenna (FTTA) application for the wireless services. See this for an example: https://www.opticalzonu.com/solutions/uhfandvhf/


Documenting Fiber Optic Cable Plants
Q:
I am looking for information or training materials on documentation standards for OSP cable.  We currently have a number of large backbone cables along with mid span cables.  I know companies like the phone company labels each cable with a number and terminals off of the mid span drop with the specific pair numbers.  Is there a standard way to label each cable, mid span cable, splice box, terminal, etc.?
A:
The usual way is to document every fiber in every cable with a fiber designation, color code and connections on each end. There are some standards on numbering schemes but most companies I know use their own designations created as they got started. There are software packages that will do this work, simplifying the process,

Q:
How often are FOA courses (such as CFOS/D) updated? And when they get updated, what happens to those who would have done a previous version?
A: The FOA knowledge base is updated continuously, reflected first in the FOA Guide online (FOA Guide), then in the curriculum materials for courses at our FOA Approved training organizations and Fiber U (Fiber U). Textbooks are updated every few years, generally just tech updates, but sometimes with major additions like the large section on OSP construction added into the OSP book.
If you took your certification a few years ago, there are new courses at Fiber U and a FOA Update Page that we use for new information that was first published in the newsletter. And of course reading the FOA Monthly Newsletter FOA News will help keep you up to date on fiber optic tech and applications.


Measuring Short Cables WIth A Long Launch Cable
Q:
Is it correct to measure a 300m fiber optic last mile with a 2Km launch cable? I think it is not, but I’d like to hear your comments.
A: Why would you think it is not correct?
Q: A 2Km launch box must be used with a 20uS pulse width, to eliminate the dead zone. Shorter pulse widths are too “weak” so the OYDR will not reach the end of the link. That’s why I think it’s not correct using the 2Km launch box in links shorter than 80Km/90Km.
A: You have cause and effect reversed. If you are trying to measure a very long fiber, 80-90km, you need a lot of power in the OTDR pulse, so you use a very wide pulse. In order to get past the dead zone with that long pulse, you need a long launch cable, like 2 km. But if you are trying to measure a short cable, say 300m, you use a very short pulse, 5ns or so, for higher resolution. The OTDR range would only need to be a few km, so the shorter pulse works. As long as the OTDR range is longer than the launch cable plus the cable to test, it’s perfectly OK. A shorter launch cable would work and might even allow a shorter test pulse for higher resolution, but the length of the launch cable only needs to be long enough to reach past the dead zone and allow measuring the cable you want to test.

Fiber In Antarctica
Q: Does anyone know if there is any cable solution to be installed in Antarctica? The climatic conditions involve installing the cable directly on the ground, withstanding temperatures as low as -30° Celsius.
A: There have been fiber optic cables in the Antarctic for over 25 years. In the 1990s, the fiber optic test equipment company FOTEC built a computerized test  system that was installed at Amundsen-Scott base to test about a half-dozen cables over the winter. All worked fine. A few years ago we met the engineer who installed it at a conference. She told me some of those cables were still being used.

Seeing Splices On OTDR Traces
Q: The reason why I am reaching out is because the CEI is having trouble understanding that not all trace files will show splices. As we both know that means that there is low loss and the network will work more efficiently. I was wondering if you could possibly help give a more in depth explanation so everyone can understand why they are not seeing splices.
A: Nothing in fiber optics is more confusing that an OTDR trace!
First it is necessary to understand how the OTDR measures loss, so start on this page in the FOA Guide: https://foa.org/tech/ref/testing/OTDR/OTDR.html When you get about 3/4 down the page, there is a section called “OTDR Measwurement Uncertainty”  that explains the way a splice loss is measured and the uncertainty of the measurement caused by the difference in backscatter coefficient in the two fibers being spliced.
Next consider how a splice is made - fusing or welding two fibers together. The typical loss of the splice is under 0.1 dB. The difference in fiber backscatter can cause directional loss variations higher that the loss of the splice. If the difference in backscatter is 0.1 dB and the splice loss is 0.1 dB, in one direction it will show 0 dB loss and in the other directin it will show 0.2 dB loss, so the average is about right, 0.1 dB. This is of course how we get “gainers” when the backscatter difference is much higher than the splice loss.
But also consider this. The OTDR digitizes the signals in both axes. If the dB range shown is 40dB and the digitization is 10 bits, each bit represents 0.04 dB. A good fusion splice can be so small, the OTDR cannot detect it because it is less than 1 bit of the measurement resolution.
This is the reason we tell people that documentation is so important. If you know where the splice is, you can look for it and pat yourself on the back if you can’t find it because you are so good at splicing!


What is the application for 10G to the home?
Q:
What is the application for 10G to the home?  Streaming 4K requires 25M, even a family of 8, each watching their own program would only require 200M.
A: The use of 10G is not just for bragging rights. With 10G, you can serve up to 256 (or sometimes more) users, making it a viable alternative for very dense populations. Of course, it can also serve fewer business users who want higher bandwidth than regular GPON.
Utility damages slightly increased since 2019, per DIRT Report
The Common Ground Alliance (CGA) recently announced the findings from its 2021 Damage Information Reporting Tool (DIRT) Report, and the datas indicates that damages have increased since 2019.

Fiber Characterization
Q:
After installing a long haul backbone fibre, what tests are required on the fibre plant to ensure optimum performance of DWDM. (I understand the need for having OTDR traces.) Are there any FOA Guides that explore such tests?
A:
FOA has a page in the FOA Guide covering this kind of testing - it’s called “fiber characterization.” The page is Fiber Characterization and Testing long haul networks (CD, PMD, Spectral Attenuation)

Mating Cycles
Q:
I’m a NASA contractor and recently we came across a interesting and yet perplexing question.  Does a connector lose a mate cycle every time we put it under the scope for a cleanliness inspection?  We want to catalogue each time we lose a mating cycle and wondered if that counted as well. 
A:
No you would not lose a mating cycle. The connector is well separated from the lens of the microscope. If they touched, it would disturb any dirt on the end of the connector you were trying to inspect and get the microscope lens dirty. A mating cycle is only when mated to another connector - PC and APC connectors have contact between the polished fiber ends and that is what causes wear. Microscopes should not cause mating, not should most power meters for testing, but test sources and meters with fiber pigtails for connections would count as a mating cycle.

Removing Data Center Cables
Q:
I’m wrecking out fiber optic cables at the data center.  They get very tangled if the connectors are intact. Co-workers are cutting the connectors off to make pulling the fiber optic cables through the fiber troughs easier. I was concerned about fiber shards when connectors are cut off.
A:
Cutting off connectors should not produce fiber shards. The plastic coatings on the fiber should keep that from happening. It is OK to cut off connectors or cut the cables into shorter lengths to ease the removal of tangled cables.

Connecting OS1/OS2 SM Fiber
Q:
Can OS1 and OS2 fibers be cross-connected?  Application is for low bandwidth devices with a maximum of 1GB Ethernet connections.
A:
OS1 and. OS2 (G.652) fibers are essentially the same geometrically; the only difference is the manufacturing of OS2 removes the water molecules that cause the water peak at 1244 and 1383 nm.

FTTH Software
Q:
Do you have any recommendations on FTTH software? A search shows a dozen or more offerings but I don’t know anyone using them. Are you familiar with any?
A:
We asked several people who are knowledgeable on software and here is what they said:
It would depend on the application or what you need the software for…
  • For GIS based mapping: Esri
  • For fiber network management systems (FNMS [design/planning and operations]): OSPinsight or Vetro
  • For automated HL design: OSPInsight as well as Biarri
  • For Tier 1 type telecom operator FNMS with BSS/OSS integration: Ericsson NE (Networks) which was based on old Tirks. Another is NetCracker.
  • For GIS enabled construction / project Management: Vitruvi
If I had to start a small to mid sized FTTH system, I would consider ESRI and OSPInsight.

How Light travels In An Optical Fiber
Q:
Is there a generalised ratio between the length of an optic fibre and the length of the path actually taken by a light pulse inside that fibre? If yes, do OTDRs factor in such differences in any way? or they such sown the length of the actual path of the light pulses?
A:
Each optical fiber has an effective independent of refraction. The index of refraction is the ratio of the speed of light to the speed of light in the material: n=c/v where n=index of refraction, c=speed of light in a vacuum and v=speed of light in the fiber.
For an optical fiber, the manufacturer measures the index of refraction which is usually in the range of 1.47. Corning SMF-28 singlemdoe fiber for example is specified at 1.4670 @ 1310 nm and 1.4677 @ 1550 nm.
So if you use the equation above, the speed of light in SMF-28 fiber for a 1310nm pulse is c/n or 300,000 km/s divided by 1.4670 = 204,500 km/s.
When an OTDR measures length, it actually measures the time its test pulse takes to go to the end of the fiber and return, so the distance is 2X the actual fiber length. The distance is speed x time.
If a fiber is 1 km long and the speed is 204,500 km/s, the  time forlight to travel the 1km is 1/204500 = 0.00000489 seconds or about 5 milliseconds.
OTDR will measure that fiber as 10 ms becasue its pulse has to go both ways, and it would calculate the length as i km, using that effective index of refraction of 1.4670.
Back to your original question, the index of refraction is the generalized number based on how light travels in the fiber.

Excess Cable In Ducts
Q: Do you have any established characterization on the ratio of the length of optic fibre to the length of its duct (to account for twisting of the fibre inside the duct).
A: The cable after pulling into the duct and no longer under tension will be about 1-2% longer. And remember the fiber is about 1% longer than the cable.

Slack/Service Loops In Manholes
Q: What is the recommended percentage of slack left in manholes for longhaul transmission links?
A: Not so much a percentage as actual length. If it includes a splice, the fiber which will be stored in service loops need to be long enough to conveniently do the splicing outside the manhole - typically 10-15m for each cable. If there is no splice but just provision to pull the cable back down conduit to repair a dig-up during restoration, the distances should be about the same or maybe a bit longer - say 20m of cable..


Do APC Connectors Show Reflectance On An OTDR Trace?
Q:
I was testing a 500meter cable with 1000m launch. In the first event the otdr sensed a splice loss instead of a connector and reflectance. The connector is APC . Is it possible to have no reflectance at all. Pulse at 10ns and duration of 15secs.
A: A good APC connector can show no reflectance. One of our instructors who wrote the OTDR training course when he was at AT&T did some tests for FOA a few years ago. Here are two traces that show the reflectance is so low it is in the noise of the trace.

I seem to be having an issue finding fiber protection sleeves that can slide over the 3mm patch cable.  I bought a sleeve that said it with made for “single fiber fusion” but the thru hole which I would side the cable thru prior to fusion is too small for the patch cable.  When I try and look on-line for specifications for the thru-hole size, prior to fusion final melting of the glue in the sleeve, all I find are post-melting diameters, none which are even close to being able to handle the 3mm patch cable.
A: Splicing pigtails involves splicing the fibers only and the cables are secured separately. The usual method of splicing on pigtails is to splice the fibers and use the heat shrink tube to seal the splice and the fibers from the outside air and protect it from stress. The splice is placed in a splice tray. On either side, there is 2-3 feet of fiber exposed from the cables being spliced. The splice tray has clamps for all of the cables being spliced on the edges of the tray and the fiber to the splice is coiled neatly on the splice tray. The jacket of the pigtail is clamped at the edge of the splice tray but  ends there, so only fiber is coiled in the tray. If you try to coil fiber, the bulk of the cable can get to be a problem where it’s coiled with the bare fiber. You can get heat shrink protectors for fibers of 250 to 900 micron diameter buffers, but not for jacketed cables.


Important Questions From The Past


Managing And Maintaining a Fiber Optic Cable Plant During Its Lifetime.
Q: Are there guides / recommendations for optic fibre cable life cycle management? (outside plant) including rehabilitation / replacement timelines together with factors that may alter those timelines ( such as seismic activity, extreme weather, human activity-induced fibre cuts etc) also including typical performance deterioration over the life cycle, and the performance levels at which replacement / rehabilitation happens. Or does it happen (and is it normally expected) that operators replace entire sections of fibre (say 400 km) as part of routine maintenance?

A: There is a saying here in the US that in fiber optics “the most common cause of failure is “backhoe fade” in underground cables and  “target practice” for aerial cables.” In other words, damage caused by humans. We know of many fiber optic cable plants that have survived natural disasters like earthquakes - in fact there is a lot of work today using regular cables used in communications to monitor for seismic activity. Fire can be a problem in remote areas, but often it’s because the poles are burned causing the cables to fall.

Over the years we have questioned cable manufacturers about the lifetime of fiber optic cable. They don’t like to make definitive statements but we have been told that based on the cables installed in the past that 40 years is a probable lifetime for most cables. There are certainly cables in use today that are over 30 years old already. The glass fiber is not a problem, it’s the protection from the cables that will eventually fail. Installation techniques can have an effect on the longevity. For example splice closures should be sealed properly to prevent ingress of moisture or dirt. Cables should not be installed with bends below the rated bend radius or with excess tension.

FOA has always told users that fiber optic cables do not need maintenance (https://foa.org/tech/ref/user/maintain.html), a response to some people advocating periodic inspection and cleaning of connections, for example. That’s just more likely to cause damage.

When an accidental break in a cable occurs, we have guidelines for restoration (https://foa.org/tech/ref/restoration/rest.html), and planning for restoration when building the cable plant is very important.

Someday you will certainly want to replace cables, often well before the lifetime of the cable, but generally because you need more fiber or the older fiber will not support the network speeds you want for upgrades. Planning for more fiber by installing more cables can be eased by installing spare underground ducts when first installing cables - here in the US, we call this “Dig Once” (https://foa.org/tech/ref/OSP_Construction/Underground_Construction.html). Testing fibers for higher speeds is called "fiber Characterization” (https://foa.org/tech/ref/testing/test/CD_PMD.html) and is routinely done when speeds above 10G or certainly 100G are considered for older fibers.

Knowing that the lifetime of fiber optic cable plants are ~40 years, it makes sense to plan ahead for future applications, installing lots of fibers, leaving lots of open duct space and choosing network architectures that will not obstruct upgrades. See the article on Netly's network above.


Fiber Optic Color Codes Reference Chart
Q: Has anyone made a fiber optic pocket reference chart that has cable color orders, frequencies, or other commonly used info on it?
A: The FOA has a page on its Online Guide that covers color codes (https://foa.org/tech/ColCodes.htm). It is the most popular page in the FOA Guide! It works great with a smartphone.

Is There A Standard For Fiber Optic Installation?

Another question we get often is "Is there a standard for fiber optic installation." The answer is yes, but not from the usual standards groups you might expect. Over 20 years ago, the National Electrical Contractors Association (NECA) asked FOA to help create a standard for installation. That standard, ANSI/NECA/FOA-301 has been updated three times already and is about ready for another update.

Unlike most of those groups who charge you a fortune for standards, FOA covers the cost so
ANSI/NECA/FOA-301 is available free from FOA.

Need A Fiber Optic Course Onsite? Invite an FOA School To Come To You

FOA often gets inquiries from an organization that has personnel that needs training in fiber optics. Recent inquiries have included contractors, a manufacturer of high-reliability products using fiber optics and a cable manufacturer. In many cases, where there are several people needing training, FOA can recommend a FOA Approved School and Certified Instructor who will come to their location to teach a class. The advantage  is of course the savings in travel costs if the class comes to you, but it also offers the opportunity to customize the course to fit your needs, even use your equipment or work on your components, so the training is more relevant to those taking the class.

Contact FOA to discuss the idea of a custom, on-site class to see if it will better meet your needs.



FOA/Fiber U On-The-Job Training (OJT) Program

The FOA Fiber U OJT program for novices combines online study at Fiber U with OJT with mentoring by experienced co-workers and their supervisor to help new employees develop into FOA-certified technicians in only one year. 
OJT

The FOA Fiber U “OJT-To-Cert” program  includes both fiber optics and premises cabling (copper, fiber & wireless), so it covers techs working in both outside plant and premises jobs. 

Like other FOA programs, the OJT-To-Cert program is free. If you and/or your company is interested in the FOA OJT-To-Cert program, contact FOA.

To explain how OJT works and FOA's OJT-To-Cert program, FOA created a short video: Lecture 62: On The Job Training For Fiber Optics Using Fiber U     




FOA Direct Certification Program For Experienced Fiber Optic Techs

Experience Plus Online Study At Fiber U = FOA Certification

What Fiber Techs Don't Know -

What We Learn From FOA Certification Tests

As FOA moves more testing over to our digital online testing system at ClassMarker, we have access to more data about our testing, including what questions and topics on the tests are answered incorrectly most often. Having this data gives us an opportunity to evaluate the questions and how they are stated, but more importantly it allow us to help our instructors teach the subjects and us to change our curriculum and online courses to emphasize these particular topics. These are some of the topics that we have noticed are answered incorrectly more often in FOA and Fiber U tests.

Most of the questions missed are on testing.

1. OTDRs - particularly what information is in the OTDR trace.

2. The difference between dB and dBm

3. Loss budgets - both the concepts and doing the math

4. Insertion loss testing - single-ended or double ended for testing patchcords or cable plants, how to set 0dB references

5. Units of measure - fiber is measured in microns, wavelengths in nanometers, etc.

At FOA, we're working to add Fiber U MiniCourses on these topics and working with our schools to emphasize these topics in their classes.

If you are going to be taking a FOA certification course or test in the near future, these topics should be on your final exam study list.

What We Learn From Hands On Labs
We learn about students performance in hands-on labs from the feedback of our instructors and our own experiences too. One big problem is the use of hand tools. Growing up today, you learn how to use keyboards, mouses and touch screens, but decades ago, you also learned how to use basic hand tools. This is big enough of a problem that we're considering adding some video lessons on basic hand tools to prepare students for cable prep, termination and splicing that require the use of hand tools.

FOA
                            Reference Guide to Fiber Optics book

FOA has now translated the Basics of Fiber Optics textbook in our Online Guide into Portuguese, joining Spanish and French translations. For those speaking Portuguese, we have the technical information and for schools we also have curriculum available.

Here is the FOA Guide in Portuguese, Spanish and French translations.


Time To Learn - Online

Some schools have been closed during the pandemic, so FOA has been working with them to create new online learning experiences that can in some cases lead to certification online. FOA certifications are still based on the KSAs - knowledge from the classroom, skills from the labs and abilities judged by instructors or proven by actual experience.

ZOOMing
Much of what we're doing benefits from the capabilities of "Zoom." Others have created videoconferencing apps, but none work so well, especially with limited bandwidth. We've seen remote labs that have an instructor showing students how to use the tools they were sent then watching them duplicate their actions. We have worked out methods to use Zoom to proctor FOA's online certification exams.

Blended Learning
While most FOA schools have suspended in-person training during this period, some are offering a "blended learning" option. That means that students sign up for a FOA certification course, take the classroom sessions on Fiber U with the assistance of a FOA certified instructor. Now online instruction can include reviewing the labs using the
Fiber U Basic Skills Labs, then when it's possible to attend classes at the school, complete the hands-on labs and take the FOA certification exam.

Online Remote Labs
Alternatively, some schools are experimenting with "remote labs," where the students get sent tool kits and components and labs are conducted by videoconferencing. Before the labs, the students may watch demos by their instructor on videoconferencing and/or review the relevant "virtual hands-on" lessons in the Fiber U
Fiber Optics Basic Skills Labs  so they will already know the steps in the exercises.
And Fiber U has the new Fiber U DIY Basic Skills Lab lesson with directions on how to purchase inexpensive tools online and use them to learn basic fiber optic skills. Videoconferencing allows the instructor to remotely monitor their work and provide help as needed. Contact the FOA for more information.

FOA Zoom Exam Proctoring

Online Certification Testing
FOA has all its certification tests available online, both for use by our schools and by our direct "Work to Cert" applicants. All FOA certification tests require a proctor to oversee the applicant taking the exam. In this time of social distancing, getting a proctor can be difficult, so FOA now has procedures for online proctors administering the exam.
Contact the FOA for more information.
 
OJT - On-The-Job-Training
Many novices get a job and learn on the job. They usually have an experienced tech who helps them gain the knowledge and  learn the skills they need to perform their job. Thinking about this in relation to the 
FOA KSAs, the knowledge, skills and abilities needed by a fiber optic tech,  the tech will learn skills but not the basic knowledge that helps them understand the processes involved. FOA can offer help here with our
FOA's OJT-to-Cert Program, using our Fiber U online self-study programs. While the tech learns on the job, they become a Fiber U trainee, getting the knowledge they need, while working under their "mentor" at work. This is particularly good for contracting companies who need techs but do not have the usual training courses available. Interested in OJT programs? Click on the link below or contact FOA for more information.

FOA's OJT-to-Cert Program  
 

fiberu.org

FOA offers free online self-study programs at Fiber U. Many users are preparing for FOA certification programs - taking courses at our schools or using the "Work-to-Cert" program. Some of our schools are requiring Fiber U programs as prerequisites for their classroom courses so they can spend more time on hands-on activities.

Latest FOA Book: Fiber Broadband (Paperback and Kindle)

FOA Guide To Fiber BroadbandIn less than half a century, fiber optics has revolutionized communications and to a large extent, society in general. Broadband, what many today call high speed Internet access, has become a necessity for everyone, not a luxury. The technology that makes broadband possible is fiber optics, connecting the continents, cities, and just about everybody. Even fiber to the home (FTTH) brings broadband to hundreds of millions worldwide.

How did we get from an era when communications was making a telephone call or sending a telegram to today’s world where every piece of information – and misinformation – is available at the click of a mouse or touch on a screen? How did we get from a time when a phone was connected on copper wires to being able to connect practically anywhere on a handheld device with more computing power than was available to scientists and engineers only decades ago?

How does broadband work? Without fiber optics it would not work.

This book is not the typical FOA technical textbook - it is written for anyone who wants to understand fiber broadband or fiber optics or the Internet. It's also aimed at STEM teachers who want to include communications technology in their classes. This book will try to explain not only how fiber broadband works, but how it was developed. It is intended to be an introduction to communications technology appropriate for a communications course at almost any level (junior high, high school or college,) for managers involved with broadband projects, or for anyone who just wonders how all this stuff works.

On Safety

The FOA is concerned about safety!
FOA considers safety an integral part of all our programs, curriculum materials and technical materials. We start all our textbooks and their online versions with a section on safety in the first chapter, like this: Before we get started - Safety First!
 
There are pages on the FOA Guide on Safety procedures Including Eye Safety  and. Digging Safely 

And a YouTube lecture: FOA Lecture 2: Safety When Working With Fiber Optics
 
In our OSP Construction Section, these pages cover many safety issues including those related to the construction of the cable plant: Project Preparation And Guidelines, Underground Cable Construction, Underground Cable Installation and Aerial Cable Installation.
 
There is even a safety poster for the fiber activities: PDF Safety Rules For Fiber Optics
 
Other Safety Resources:

There is a toll-free "call before you dig" number in the USA: Dial 811. See www.call811.com for more information in the US. Here is their map of resources by states.

In Canada, it's "Click Before You Dig.com" They also have a page of resources by US states and Canadian provinces.

The Common Ground Alliance has an excellent "Best Practices Guide" online

The US Department of Transportation has a website called "National Pipeline Mapping System" that allows one to search for buried pipelines.

Your Name, CFOT® - It pays to advertise!

The FOA encourages CFOTs to use the logo on their business cards, letterhead, truck or van, etc. and provides logo files for that purpose. But we are also asked about how to use the CFOT or CFOS certifications. Easy, you can refer to yourself as "Your Name, CFOT" or "Your Name, CFOS/T" for example.

Feel free to use the logo and designations to promote your achievements and professionalism!
