Wired Towns Edge Out Big Cities
A city’s size no longer is the key factor in building vibrant local economies. It’s all about connections to other places, a new study at Michigan State University suggests. The study found that a city’s population was the most important factor for its economy until the 1950s, when the spread of commercial air travel fostered more cross-country business networks.
That trend continued with advances such as teleconferencing and the growth of the Internet.
Some large cities—including New York, Los Angeles, and Chicago—built on those networks and maintained their economic clout, according to the study. Other cities—like Detroit, Cleveland, and Pittsburgh—were unable to effectively capitalize and now are considered “poorly connected.” This holds true for the overall economies of the cities and for specific sectors such as manufacturing and transportation and communication, Neal said.
And then there are communities that recently have developed connections to become “wired towns,” he says. These are smaller cities that were essentially insignificant 50 years ago but have emerged as major economic centers, according to the study.
Wired towns include the Raleigh/Durham area of North Carolina—which pooled its regional resources to focus on innovation and creativity—and Miami, which took advantage of its location to serve as the primary link between North, Central, and South America.
Neal says the findings could help city planners and officials better formulate plans to stimulate their local economies by helping them know where to focus their efforts.

Some cities like Chattanooga, TN also realize this:

Who's Beating Google and Verizon to Gigabit FTTH Speeds?
Last year, the big news was Google wanting to build a gigabit FTTH network in a US city as a test and last month we mentioned Verizon's trial of 1 Gb/s connectivity over its FiOS infrastructure in Taunton, Massachusetts (Connected Planet.) While we were reading all this, we have a gigabit FTTH network being built -  an entire city-wide network committedt to gigabit FTTH in Chattanooga, Tennessee! "Chattanooga Gig" is installing the fastest FTTH anywhere, as well as a complete "Smart Grid" system.
Chattanooga's community-owned electric utility EPB is installing a 100% fiber to the premises network, built to run America's first true Smart Grid and offer residential high speed Internet, video and telephone services. Alcatel-Lucent provided the GPON equipment. About 125,000 subscribers are already connected with the complete 170,000 subscribers connected by the end of 2010.
Chattanooga is now 10 times faster and 10 years ahead of FCC’s National Broadband Plan calling for 100 Mbps speeds for 260 million households nationwide by 2020. Interestingly, the system is being partially funded by US Stimlus grants, but not from the broadband funds, it's Smart Grid funds from the Department of Energy. The Smart Grid portion of the network is planned to be completed in 2012.

FOA Reference Guide To Outside Plant Fiber OpticsFOA Releases Certification On Outside Plant Fiber Optics, Offers Online Study Guide, New Reference Textbook
With the CFospT outside plant certification, the FOA focuses on OSP fiber optic network design, installation and maintentance. A CFospT certified tech must know the ways that fiber is used in the OSP, how it is installed, tested and maintained. While a CFOT might only have a basic knowlede of fusion splicing and OTDR testing, for example, a CFospT will be knowledgeable and skillful in those areas - and more.
Reference materials for the new CFospT are the printed textbook, the FOA Reference Guide to Outside Plant Fiber Optics (right) as well as eBooks from Amazon for the Kindle or Apple for the iPad/iPod/iPhone and the OSP reference section of the FOA Online Reference Guide which now includes a self-study guide to the CFospT exam.

More information on the FOA Outside Plant Fiber Optic Technician (CFospT) certification.

Want to know more about OSP? There's OSP Magazine for that - and a trade show, OSPExpo, running this fall in San Antonio.


FOA @ IBEW Training InstituteNTI 2010The International Brotherhood of Electrical Worker (IBEW) held their 21st National Training Institute at the University of Michigan August 1st thru 6th. The Institute trains Apprenticeship/Journeyman instructors on the newest training techniques and technologies from the industry experts.
The Fiber Optic Association participated in the NTI Trade Show and the week-long training program for about the 15th time. The FOA introduced its new Certified Fiber Optic Outside Plant Technician (CFospT) training /certification program. The program is targeted to the workers that design, install, and test fiber optic systems used by telecommunication companies, cable TV, and power companies. The new program will debut later this fall at Gateway Community and Technical College, Smart Grid program. 
Also unveiled, was the Kindle version and iBook of the CFOT reference guides. An Apple iPad/iPhone app of the iBook was also shown. It will be an interactive self-study E-text that will cover the text material and the installation skills. In addition, The FOA made a midweek evening presentation covering the FOA certification programs to 25 NTI participants.   
During the week of NTI, The FOA offered daily morning and afternoon sessions of the Certified Fiber Optic Technician program.  The 25 newly certified CFOT technicians included telecommunication instructors, electrical instructors, training directors, and power lineman instructors. These new CFOT’s can become CFOT instructors and begin to offer the CFOT program at their local JATC’s. These new instructors will become part of the 250 + FOA affiliated training sites located throughout the world.


Corning Hosts Fiber Optic Instructors For Training
Corning Hosts Fiber Optic instructors
Corning recently invited a number of fiber optic instructors to Hickory, NC HQ for training on new technology and, of course, Corning products. It was a great session with the instructors there - many FOA instructors along with FOA President Jim Hayes - getting amazing access to the know-how of the #1 fiber company. Corning personnel made many presentations over 2-1/2 days covering new technology and Corning products.
What did we learn and discuss? Two big topics were the revised OFSTP-14 multimode test standard and cabling for data centers to accomodate 40 and 100 Gb/s Ethernet. We'll be covering these topics more in the next few months.

New OSP Reference Section on the FOA Online Reference Guide website
Joining our basic fiber optics and premises cabling sections on the FOA Reference Guide website is a new outside plant reference section that covers materials like that in our new textbook. The material is ready for use and will be followed shortly by a self-study guide.
Both the OSP textbook and website are being prepared as references for the new FOA CFospT outside plant technician certification, due this fall.

New, FOA Videos Now on videosand a new reference guide page on Polarity

The FOA Online Fiber Optic Reference Guide has become very popular - perhaps the most popular technical website ever, typically with over 30,000 users downloading about 1/4 million pages monthly! We continue updating materials regularly, keeping it as up to date as possible.
Just this month, we added a page on "polarity" for fiber optic networks. Although it seems obvious that connecting transmitters to receivers is required, how it's accomplished can be confusing! We already updated the Premises Cabling sections in conjunction with publishing the  FOA Premises Textbook and are now focused on outside plant applications (OSP) with a new OSP reference section. We've already added a new page on chromatic dispersion (CD) and polarization-mode dispersion (PMD)

It's Now A Lot Easier To Find A FOA-Approved Training OrganizationFOA-Approved School Map Zoom to CA

Most phone calls we get regarding finding a FOA-Approved training organization want to know two things: what school is closest to me or what school offers the certifications I need. That can be difficult, since the FOA has almost 200 training organizations we have approved worldwide!
We've been looking at ways to make it easier, and we think we've got a good solution. In fact we have two solutions.
First we have added a sortable table of all the FOA-Approved schools.
You can also use our FOA Google Map Application to find FOA-Approved schools.

Good Question! Tech Questions Worth Repeating

Tech Hint: Did You Know You Have A Fiber Optic Tester In Your Pocket?
Yes! The camera in your 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 sent us some photos showing how this works. See below.

Link Lengths on Long MM Fiber Cable Plants
Q: I’m in the process of proposing some LAN switches for a client which involves selecting some 10G SFP modules based on the type of fiber presently on site. For instance one of their sites has OM3 MMF 50/125 fiber installed and I need to know the cable distance limitations. I have this document but I’m not sure where the OM3 MMF 50/125 fibre sits within it. I can’t make sense of the Modal Bandwidth spec? I assume because it’s OM3 it has a cable distance of 300m?
How do I work out the Modal Bandwidth? Is this specific to the fiber or the module?

A: Modal bandwidth is one of the standard specifications for multimode fiber, tested by the manufacturer. It is generally not tested in the field today. Each network specifies a maximum length based on the bandwidth of the fiber that is 100% certain to work with the network equipment.
 This is a webpage that defines the specifications for fiber types and references the standard designations: http://www.thefoa.org/tech/OM.html
 This webpage has a listing of most types of networks to 100 GB/s and their specified cabling distances with different types of fibers:
http://www.thefoa.org/tech/Linkspec.htm

Mixing 50/135 and 62.5/125 Fibers
Q: I work at a college campus. I have been asked about using 50/125 micron pigtails and fusion splicing them onto the existing 62.5/125 fiber to create a 10GB fiber back bone. Will this work?
 
A: I don't think that's going to work. The Ethernet committee has published specs on all their networks (see http://www.thefoa.org/tech/Linkspec.htm) and at 10G 62.5 fiber is only good for about 33m. One does not know the quality of older fibers and many had serious bandwidth issues with VCSEL sources. Furthermore, mixing 50 and 62.5 fiber can lead to up to 1.6 dB  loss when going from 62.5 to 50 micron, (http://www.thefoa.org/tech/fib62-50.htm) using up most of your loss budget ("Linkspec" link above). Even fusion splicing old 62.5 fiber can cause bandwidth issues!
If the goal is 10GbE, I'd recommend a new cabling system based on OM3/OM4 fiber. Furthermore, I'd use LC connectors to prevent mismatched fiber connections! This is a webpage that defines the specifications for fiber types and references the standard designations: http://www.thefoa.org/tech/OM.html

Using OM3-OM4 Fiber
Q: We're currently in the process of linking up 2 locations through a fiber connection. The network has a speed of 100 Mbps. The switches at both ends are <company> switches, and the optic ports are SFPs plugged into these switches. <company> states that their switches work with OM1, OM2 and OM3 fibers. As a side note, they mention that they do not use SFPs with VSCEL technology at this time.
My question is, Even though the SFPs do not support VSCEL, can we use an
OM3 type of cable to link up the 2 locations?

A:Any multimode fiber will work with LEDs or VCSELs. The design of laser-optimized fibers (OM3 and now OM4 - see http://www.thefoa.org/tech/ref/basic/fiber.html) is simply to refine the graded-index profile to reduce modal dispersion, necessary for using VCSELs at 1 Gb/s and above. LEDs work perfectly well in these fibers. LEDs are not used in faster networks than 100-200 MB/s simply because LEDs are not fast enough - the devices themselves have limited bandwidth, and they suffer badly from chromatic dispersion (also in that link above).
OM3 fiber is more costly than OM2 (and about the same as OM1), but if the intention is to ever upgrade to higher speeds, it's a good investment.
Some source manufacturers have recommended customers only use VCSELs as they are so cheap!

Telco Fiber Types
Q: A customer called for a SM fiber for a OC-48 d-marc extension from one floor to another in a building. So that is what we installed. I was taught that visible red laser light uses single mode fiber for high speed xfer. However, the OC-48 light seems to be invisible which I think is infrared. Should we have used MM fiber? Do you know the light frequency of an OC-48 circuit?

A: All telco transmission such as an OC-48 link will use singlemode fiber with a 1310 nm or 1550 nm laser source which is quite invisible to the human eye. The only use for red lasers and singlemode fiber is for tracing fibers to ensure continuity or proper connections. Red LEDs are used with plastic fiber for short links like consumer audio - their only use for links.
Who taught you that red lasers use SM fiber for high speed transmission? I want to chastise them!

Life Expectancy of Fiber Optic Cable
Q: I'm trying to find information relating to the expected working life of fibre cables in different applications, specifically in underground applications within conduits and aerial on existing utility poles.

A: We have talked to cable manufacturers who say cables are designed for approximately a 40 year lifetime (a number that sometimes shows up in bid packages - see this package .) The glass fiber is good for millennia, of course, as long as the coatings remain hermetic, but the plastics used in the cable will have a shorter lifetime. This lifetime only applies to a cable, which can be compromised by damage to the cable during installation (cuts in the jacket, pulled with excess tension, kinked by bending around a smaller radius that specified for the cable, etc.) In addition, you have the lifetime of splices and terminations and any other hardware involved. Where reliability is a concern, fusion splices should be used and splice closures carefully sealed and perhaps even purged and pressurized with dry nitrogen.
The biggest cause of failure is damage - from "backhoe fade" -digging up buried underground cables - or "target practice" on aerial cables (a problem you may not have like we do here in the USA!) One major cable incident happens each day in the USA on the average!
We suggest you also consult with cable manufacturers.

Cable Twists
Q; I work for the U.S. Navy and am trying to find information on fiber optic cable twisting when loaded & unloaded from a drum or spool. Although we are winding the cable on & off the drum and not from the end of the spool such that we'd impart a twist, we are still seeing a twisting in the cable.  It does see a load (~200 lbs) but it's always directly through the cable length.  We're trying to understand how the twist happens, how much it might grow and what are the potential changes in physical properties to the cable because of the twist.  I think I've been able to loosely explain what our issue is and hope that you might be able to point me in a direction that I could get some more detailed information (reports, etc.).

A: All cables are manufactured with some twist in the components. The fibers and strength members are helically wound around the central strength member in OSP cables. Many cables have a counter-helical twist that revolves clockwise for a short period then counter-clockwise for an equal period to reduce the tendency of the cable to untwist under load. The fibers are isolated from the strength members in tight buffer cables, usually inside them, or in buffer tubes where they are loosely enclosed to allow the cable to withstand high tension loads.
Cables are designed to be pulled by the strength members and those are isolated from the fibers to prevent damage. Some cable designed to be left under tension after installation like ADSS (all dielectric self-supporting aerial cable) is designed to have the jacket under tension without causing stress on the fibers.
If you have a cable being loaded by pulling on the jacket and the cable jacket is not designed to be used for pulling, it will stretch and the internal structure will untwist because of its helical wound structure.
My question is how are you pulling this cable? And is it designed to be pulled this way. Most cables are to be pulled only by the strength members, not the jacket, may untwist when pulled by the jacket.

Pulling Fiber Cable
Q: We have to install one fiber optical cable parallel a huge water tube for two distances (2.7 Km and 3.3 Km) and we want to know if it is better to install the cable using junction boxes or just install the tube and use a pressure gas puller for each length.

A: The FOA does have information on installation in several places:
User's Guide web page: http://www.thefoa.org/user/index.html
Tech Bulletin on installation: http://www.thefoa.org/tech/index.html#anchor25731930
Online Reference Guide, Installation section: http://www.thefoa.org/tech/ref/contents.html#Install
Outside plant installation web page: http://www.thefoa.org/tech/ref/OSP/install.html
For the installation you describe, the issue is how long a distance can the cable be pulled. That is determined by the friction of the cable in the conduit and the length. A vendor, American Polywater, has a calculator software that can assist you in determining the length you can pull with proper lubrication: http://www.polywater.com/ and the pulling calculator: http://www.polywater.com/pullplan.html and http://www.polywater.com/calculators.asp
You should also always consult with the cable manufacturer.

dB - What does it mean, exactly?
Q: In FRG to Fiber Optics  Pg 51 it states "For example, the loss of ............only 1 dB/km. That means at 850nm, half the light is lost in 1km, while only 20% is lost at 1300nm" Does that mean half of the transmitted power is lost when transmiiting at 850nm? How do you derive the 20%?

A: 3 dB is a ratio of 50% in power, so a loss of 3 dB means the power is lower by 50% at the end of 1 km of fiber. Likewise, it's down another 50% to 25% of the starting amount at the end of the second km, and so on.
At 1300 nm, the loss is only 1 dB or about 20%, so there is 80% of the initial power level at 1 km, 64% at the end of the second km (0.8 x 0.8 = 0.64) and so on.

You can calculate dB from power by using dB = 10 log (power ratio)

The FOA Online Reference Guide has a page on measuring optical power (http://www.thefoa.org/tech/ref/testing/test/power.html) that has an Excel Spreadsheet that calculates dB/power ratio and dBm/milliwatts) so you can calculate the actual values.

Reference Textbook
Q: There is a 4th edition of the Fiber Optic Technicians Manual published just recently. Isn't that a FOA book? Why is it not listed as a reference for the FOA certifications?

A: The FOA wrote the FOTM in 1997 and has used it as the reference book for FO training until this year. When the price of the FOTM 3rd edition nearly reached $100, the FOA decided it was too expensive for our own training, although we had just sent the publisher the updates for the 4th edition. We decided to created our own references and self-publish, cutting out the high costs of the publisher. Now we have our own books at a fraction of the previous costs, even cheaper as eBooks on the Kindle or iPad, plus a complete website with online study guides. The FOA curriculum materials and exams were not updated for FOTM 4th ed. and references to FOTM 3rd ed will be gone at the end of the year.

Loss Budgets
Q:  have a question about loss budgets. Should you count the last connector, because you only get a loss if you mate the pair.  If the link plugs directly into a machine then are the last connectors counted?

A: This question arises occasionally because the copper equivalents offer two options, with and without connections on the end.
However, fiber convention is only to consider an installed fiber optic cable as a permanent link, This is because 1) it is necessary to connect the fiber in the link being tested with a source with attached launch cables to be able to establish test conditions and a meter with attached receive cable to test the connector on the receive end. 2) The permanent link will be used with patchcords which means the reference cables emulate real usage including the loss of the end connectors. 3) Systems manufacturers and standards committees (e.g. Ethernet) define their loss budgets based on a test which includes the loss of the connectors on each end, with usage including patchcords that provide transmitter and receiver coupling. 4) You never test by just connecting a source and meter, with the rare exception of connectors that are not designed for mating, like some POF connectors, where you use a cable substitution test.
Even if we have a cable that is used to connect to equipment directly without patchcords, the convention to include the loss of end connectors is followed, otherwise there is no way to verify the quality of those connectors.
We cover this specifically in the book, eg  on the top of page 132 of the FOA Reference Guide to Fiber Optics, on the web pages and in all the examples.


Fiber Cleaning
This is a topic we keep reminding everybody about, and here is why:
From a contrator in the Middle East: Here some samples of the connectors for SM fiber already installed in the system we were testing.
dirty connector   dirty connector
As you can see, the dirt is large compared to the size of the fiber (dark gray), and the core (not visible here) is only 9/125 of the overall diameter of the fiber! See Product News below for links to vendors of fiber cleaning products.



Measurement Uncertainty: Everyone testing fiber optics should understand that every measurement has some uncertainty - whether you are measuring loss, length, wavelength, power, etc. Knowing that uncertainty is very important to interpreting the measurement. It's worthwhile to read and understand the issue of measurement accuracy covered in this page of the FOA Online Fiber Optic Reference Guide.


Worth Reading:

FOA Tech Topics - 
A Fiber Optic Tester In Your Pocket?
Yes! The camera in your 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 sent us some photos showing how this works and the following description.
IR Viewer 850 nm  IR Viewer 1300 nm
"Your cell phone camera's image sensor can read IR light. It uses this technology to help take pictures at night.
In the advanced audio and CCTV field they have been using the smart phone camera to trouble shoot problems in IR communications. The human eye cannot see the IR light emitted by let’s say a remote control.  Well up until now we would always say that the remote is out of batteries, or either the IR transmitter or IR receiver was not working properly. Now we can use your smart phone camera to see the IR light emitted by the IR transmitter. All you have to do is turn on your camera function on your smart phone and hold it up the remote control and push any button. The cameras screen will show the IR light.
Now back to Fiber Optics. If you follow the same principals of the last paragraph, let’s say you wanted to check if a fiber port was energized. You can either use the card that is supposed to show you in a few seconds that the port was hot. Or you could plug in your meter, in this case it takes some time to find the card or if you don’t have your meter handy.  Just pull out your smart phone turn on the camera and hold it over the port. If it is hot you will see a bluish white dot in the fiber bulk head (see attached pictures)."
We tried this ourselves and found our camera phone very sensitive at 850 nm but as expected less so at 1300 nm, like all semiconductor detectors. Our phone could still see 1300 nm sources at around -20 dBm, making it very useful even for LED sources, and of course, perfect for lasers.

OFSTP-14 is DEAD! Long Live OFSTP-14!
OFSTP-14 is, of course, the TIA standard for testing installed multimode fiber optic cable plants which has been around more than 20 years and is the one TIA standard probably most familiar to contractors and installers. It has been due for updating, but TIA has been replacing many US-written standards with the equivalent international documents. 
The TIA has adopted IEC 61280-4-1 as the replacement of OFSTP-14. Most of the two documents is the same, with some important exceptions.
  • For insertion loss, three reference methods are are still approved, but the nomenclature is different.
  • OTDR testing is now an approved test method as long as you use launch and receive cables.
  • Reference test cables with "reference grade connectors" are recommended.
  • Methods are given for testing and verifying the loss of reference test cables.
  • CPR with a mandrel wrap is gone, replaced by "Encircled Flux," a complex - and not completely debugged - method of measuring the source output.
We are creating a web page to explain the differences and will give you a link shortly. In the meantime, continue testing as usual.

The FOA reference website is now online. New sections have been added on Outside Plant Fiber Opticsfusion splicing and mechanical splicing.  Check out the current Table of Contents
This month, we added a page on "polarity" for fiber optic networks.

FOA Technical Bulletins
How do you design and manufacture fiber optic systems? Choose and install one to serve your communications needs? Troubleshoot problems? The FOA Fiber Optic Technical Bulletins will provide step-by-step guidelines to help you. All are PDF files you can download, print and use.
Testing Update
Are there really 5 different ways to test optical fiber cabling after installation? Why so many? How do the measurements - and more importantly the measurement results - differ? What are the advanteages and disadvantages of each method?
Why are there 4 ways (maybe 5) to test fiber optic cables?
Do OTDRs and OLTS tests give the same results?

Draka Expands Bend-Insensitive Fiber Line
A large number of Draka fibers are available with BendBright-Elite fiber. In North America, BendBright-Elite is available in premises and outside plant cables. Draka introduced the BendBright family of bend insensitive fibers in 2002 and has since expanded the product family to four versions of bend insensitive fiber, spanning both singlemode and multimode types:
BendBright – 10X bend improvement versus standard singlemode
BendBright-XS – 7.5-mm bend radius fiber with over 6 billion feet sold
BendBright -Elite – 5-mm bend radius fiber
MaxCap-BB – OM3 & OM4 bend insensitive multimode fiber (see below re testing with MM fiber)
Bend-Insensitive Fiber Becomes Corning's Standard 50/125 Fiber -
But it means changes in the way you test with it!
Corning announced that effective April 1, 2010, ClearCurve® multimode optical fiber will become its standard 50-micron multimode fiber product offering. "ClearCurve multimode fiber is the world’s first laser-optimized, high-bandwidth, multimode fiber to withstand tight bends at 7.5 mm radius with substantially less signal loss than traditional multimode fibers. ClearCurve multimode optical fiber was first introduced by Corning in Jan. 2009 and has been validated through broad customer acceptance of the product.
Traditionally, when an optical cable experiences tight bends, some of the light can escape from the fiber core and part of the signal can be lost.  Corning ClearCurve multimode fiber is designed to keep the light in the fiber core, even under tight bends, and better maintain the integrity of the optical fiber signal.
“Corning’s 50-micron multimode fiber customers will now benefit from superior bend performance. This will result in faster and more efficient optical cable routing and installation, and significantly higher spare operating margin, at no additional cost,” said Martin J. Curran, senior vice president and general manager, Corning Optical Fiber.
Corning ClearCurve multimode fiber meets or exceeds the OM2, OM3 and OM4 industry standards for high-bandwidth, laser-optimized multimode fiber. Corning will demonstrate the performance of ClearCurve multimode optical fiber from March 23-25, 2010, at OFC/NFOEC in San Diego. Detailed product specifications are available at www.corning.com/clearcurve."

When You Test...
Most standards call for a "mandrel wrap" mode conditioner on your launch cable. The Corning announcement made us wonder what happens with this bend-insensitive fiber if you wrap it around a standard mandrel - it should not act the same as regular 50/125 fiber. We contacted our friend the Marketing Manager for the product at Corning and he confirmed our suspicions. The difference in the bend sensitivity of the fiber requires a much smaller mandrel, only 6 mm in diameter, to have the same effect.
This is detailed in Corning Application Engineering Note "Multimode Fiber Considerations for Test Jumpers,  AEN 131, Revision 2" available from Corning.

    FTTH Notes:
    FTTH or FTTC?
    That's the competition between Verizon FiOS and and AT&T U-Verse. The graph below, courtesy of IGI from their ecent report, “FiOS vs. U-verse; Architecture, Marketing, and Technical Considerations,” shows FiOS ahead but the gap narrowing as Verizon winds down their extremely aggressive FTTH program.
    Competition

    Woodstock Goes FTTH - Woodstock Telephone Company in Minnesota, that is. Delivering up to 75 Mb/s over a 450 square mile service area. (TellLabs)

    Residents of Ashby de la Launde, a small village in Lincolnshire, UK, will soon be able to install 100-Mbps fiber-optic broadband into their homes via the FTTH network. Lightwave.

    Nearly 60 homes and three businesses have started on-site digging to connect to the FTTH network to be installed around the village. The project involves the community working together to establish a privately funded network.

    US Connected FTTH homes
    According to a just released FTTH Council Report prepared by RVA, FTTH connections continue to grow in North America - 99% of which are in the US, but growth seems to be slowing, probably a consequence of the current economy. Much of the FTTH deployment in the US has been due to Verizon's $23 billion investment in FTTH, but the report noted that FTTH is now being deployed by more than 750 service providers across North America. Most of these service providers are small, independent telephone companies that are replacing their copper lines with end-to-end fiber to ensure their future competitiveness as broadband providers. Of the service providers not yet offering FTTH, a majority say they are likely to soon.

    There are tons of technical application notes and videos on the web, and occasionally we recommend some you should download. The JDSU fiber testing guide is really worthwhile, as are the ADC FTTx book and Westover video on fiber inspection and cleaning, linked below.
     
    JDSU Testing Book
    JDSU offers a free download of their Testing Guide from the Lightwave website. This is one great book which explains some basic fiber technology, but the real value is the last half which deals with OTDR testing. Not only does it give the usual info, but it covers important topics like measurement uncertainties and anomolies like ghosts and gainers.
     
    I was in the testing business for 20+ years at Fotec and think this book is one of the best fiber optic testing texts available. It's complete but comprehenisble! I used to believe that premises techs did not need OTDR training, but now OTDR manufacturers are pushing their use in premises networks. Unfortunately, the limitations of OTDRs in premises applications can cause extreme problems for those who are not aware of their limitations. So knowing hows OTDRs work is essential information to every tech.

    Job Openings
    New FOA Jobs Website
    We get many questions from CFOTs, students at FOA-Approved schools and others contemplating getting into the fiber optic business regarding jobs in fiber optics - and how to find them - so we’ve created a new web page to share some information we've gathered about jobs in our industry. The information is designed to help you understand what jobs are available in fiber optics, how to find them and apply for them.
    While the overall economy is pretty bad - you've probably heard that there are 5 times as many people unemployed in the US as there are jobs available, telecom is a bright spot - broadband is a major focus of stimulus spending in the US and countries around the world are building fiber networks as fast as possible. Even wireless companies have to build fiber for their backhaul. Cities are installing fiber linked surveillance cameras and smart traffic lights. Fiber is the link making Smart Grid possible. Companies like Allied Fiber are building large private networks. Telecom is one of the fastest growing businesses worldwide.

    If you are looking for a job in fiber optics, here is the FOA's guide to jobs.

    The FOA has created a group on FOA on LinkedIn  expressly to help our CFOTs find employment and contracting opportunities. If you are a CFOT and are interested in participating, join us on FOA on LinkedIn. If you have job openings, let us post them on FOA on LinkedIn.

    FOA Certification Top Choice

    The FOA CFOT and CFOS programs continue to gain momentum in fiber optics. Over 27,000 CFOTs have been certified by over 230 schools. Since our founding in July, 1995, we have dedicated ourselves to promoting fiber optics and professionalism in fiber optics personnel, focusing on education and certification. We are continuing to add new schools and more CFOTs as users of fiber optics learn that a CFOT is the indication of a professional, well-trained fiber optic technician. Now with FTTH (fiber to the home) finally taking off, demand for CFOTs is rising and schools are responding by expanding programs rapidly.
    The FOA now has approved programs at 200+ organizations, welcoming new additions like the Joint Apprenticeship and Training Committee of the International Brotherhood of Electrical Workers, Corning Cable Systems and AFL (and their new acquisition "The Light Brigade" for their installation training programs) and NASA's Goldstone Tracking Station. The complete list of FOA-Approved schools is at http://www.thefoa.org/foa_aprv.htm.

     

    Understanding FOA Certifications
    To answer questions on FOA certifications, we've created several new web pages:
    Overview of FOA certifications
    CFOT
    CFxT
    AFOT
    CFOS
    Training Requirements - What Schools Are Teaching
     
    Reading these will help you understand what each FOA certification covers and how to prepare for them.
     

    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 on this site 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!

     


    Remember To Renew Your Certification !

    Remember to renew your FOA certification. All current CFOTs have a ID Card with their certification data and we keep a database of current CFOTs to answer inquiries regarding your qualifications if needed. You must be a current FOA member and CFOT to participate in our online database of installers, contractors, technicians and consultants. If you forgot to renew, use the online application form to renew NOW!

    An angle cleave stops reflections for mechanical splices. Any light reflected at this angle will be absorbed in the cladding of a SM fiber and not create a reflection.
