Why Standards Meetings Are Always Entertaining!

TIA Meeting Report, February 2012

TIA Standards Meetings were held in early February 2012, as usual with some interesting issues on MM vs. SM fiber, encircled flux (EF) and bend-insensitive multimode fiber (BIMMF) being hot fiber topics. 100G networks and older fiber designs also were topics of controversy.

Several new issues were discussed.

The controversy over MM vs. SM fiber in 100G networks continues. The 10x10G MM parallel solution that requires 20-24 fibers has not been well received, so a 4x25G solution has been proposed. Unfortunately, cheap 850 nm VCSELs don't work well at those speeds, making only the 1310 nm CWDM solution on SM currently feasible. Perhaps MM fiber is facing a fate similar to UTP at higher bitrates.

ISO/IEC Standards Working Group WG3 decided to accept a UK proposal to remove OM1 (62.5/125 fiber) as a recommended medium for structured cabling standards. OM2 (50/125 fiber) is expected to be removed from future Fiber Channel standards and is likely to disappear from other standards in the future. What happens with people who have large investments in these earlier fibers who need to expand their networks and have no use for the bandwidth potential of OM3/OM4 fibers and/or do not want to worry about mixing fiber sizes?

BIMMF Technical Issues Fading – And New Ones Surfacing!
Bend-insensitive MM fiber controversies are fading as manufacturers begin to understand how to design and build them. The current view of the publicly-aired controversies of last year now seems to be "never mind!" However, one attendee privately shared with us a pair of very interesting OTDR traces of what an OTDR shows on a splice between BIMMF and regular MMF (see below). Who would have guessed that MMF could show such a gainer! This is just another proof that OTDR tests are NOT indicative of actual cable plant performance!

OTDR Traces of BIMMF  OTDR Traces of BIMMF

OTDR traces of a joint between BIMMF and regular MMF. The higher scattering of the BIMMF causes a big “gainer” in the reverse direction, illustrating why OTDRs should not be used to test cable plant loss. If you tested the end-to-end loss of this link with an OTDR in one direction only, the loss would have been 0.42 dB different than in the other direction. If you averaged the two per normal OTDR practice, the loss would be 0.04 dB, but with a backscatter gain of 0.21 dB, what loss is real with these two fibers?

Encircled Flux Requirements For Testing MM Fiber
Just before the TIA standards meeting in February, we were contacted by a test equipment company who asked us if we were willing to tell the group that some test equipment companies believed that the new OFSTP-14 which includes a requirement for encircled flux was neither feasible nor needed for field tests. We offered to not only do that but poll other test equipment companies and maybe some other manufacturers about their opinions.
We asked seven test equipment companies. Five agreed that EF was not appropriate for field use. Two thought it was fine, but they were reselling Modcon mode conditioners along with their high-priced test gear, figuring their customers could afford $3000 or so for mode conditioners. We also talked with several other manufacturers of fiber optic components. One, who had been involved with EF since the beginning, offered that "EF was never intended for field use" and confirmed saying it when I repeated it back to them incredulously. Another manufacturer complained that even using EF in the lab was proving problematic! Furthermore, several of those polled complained that the new OFSTP-14 was poorly written and organized-not even giving you a diagram of the test configuration until the appendix!
As expected, the committee response was quite negative to say the least!
But later in the day, EF cropped up several more times, including during a presentation that showed that using a short patchcord with a mode conditioner to reduce wear and tear on its connector (which requires a return to the factory to be reterminated!) negated its effects, while the presenter tried to claim the opposite! Others noted that testing EF was still not possible to calibrate. A round robin to determine if EF measurements can be correlated between labs is still probably a year away from conclusion. The discussion then focused on the fact that EF is hard to use in the field and probably not even appropriate except for 10G OM3/4 networks.

However, no one knows yet how to undo what they have done.

Perhaps more startling was the discussion that concluded that if the new OFSTP-14 was not appropriate, the prior version could still be used and remains available for purchase!

That’s why it has been repeatedly suggested that FOA write its own standards for field use by contractors, designers, installers and users. Which we have already done.

TIA Open Letter To President Obama: Jobs From Communications Infrastructure and Smart Grid Investment

"The U.S. economy benefits tremendously from the multiplier effect of the information and communications technology (ICT) infrastructure investment. Growth in the ICT sector not only creates jobs in manufacturing ICT equipment and deploying physical infrastructure, but also leads to economic growth through the creation of new businesses, services, and technologies in other sectors of the economy. For example, your proposal to develop and deploy a nationwide wireless broadband public safety network would create an estimated 100,000 new jobs in ICT industries and, over time, produce indirect benefits of an estimated $4 to $8 billion per year. Moreover, the $3.4 billion investment in ARRA for smart grid deployments could produce nearly 30,000 new jobs, while acting as seed money for a fully-deployed ICT-based smart grid with economic benefits ranging from $48 to $76 billion per year."

Fibers In The Sewers? Not a Joke!

For some years, people have chucked at the news that fiber is being run through the sewers in cities. You might remember the Google April Fool's joke about TISP, a fiber to the home project where you flushed the cable down your toilet. Well, if you see the equipment yourself, you learn that it is a very serious business that requires sophisticated equipment and practices but can save lots of money for a city wanting to install optical fibers without digging up all the streets.
We recently visited the Florida offices of "CableRunner" and saw the actual hardware used in installations. Leopold Zeindlhofer showed us how the CableRunner system works. For small to medium size pipes, wheeled robots like this install special cable trays along the top of the pipe in a well-orchestrated process.

Sewer cable installer robot

In larger storm sewers, a vehicle that actually seats two workers runs along the pipe floor while the workers install special cable trays on the top of the pipe.

The cable tray, shown below, comes in snap-together lengths and is screwed to the top of the pipe where it will generally not be immersed in the water in the pipe, as the pipe needs some air to allow proper flow.

Sewer cable tray

This particular tray shows two cables of blown-fiber tubes, another option to running regular cables.

Once you see the hardware sophistication developed for putting cables in the sewers, you understand it's no joke. They have trucks equipped for the installation process that provide power and compressed air to the robots and multiple video feeds back to the operator in the truck to monitor the progress of the installation.

Free For FOA Members: NECA/FOA 301 Fiber Optic Installation Standard

NECA 301
Because of its importance to users, contractors and installers of fiber optic networks, The FOA and NECA have agreed to make the NECA/FOA 301 Fiber Optic Installation Standard available free to FOA members.
Standards usually cover components and systems and how to test them, but rarely get into installation issues. This standard is derived from FOA educational material put in standards form and approved by ANSI as an American National Standard. It's specifically written to be used in contracts to define "installation in a neat and workmanlike manner."   FOA members can go here for instructions on how to download your free copy.

FOA Creating Useful, Relevant Standards For Contractors, Designers, Installers and Users

Ever need a quick reference to a standard but can't find a copy? Have you tried to read some of the documents and given up because of the "standardese" language? Have you been disappointed to find the standards were written by manufacturers for manufacturers and aren't relevant for contractors, installers or users? Or have you ever tried to buy a standard and just about fainted when you found our what it cost? Well, we've heard all those complaints for years. And we're doing something about it.
FOA is embarking on a new program to make standards more accessible to the world of users, contractors, designers and installers. We will start creating "One Page Standards" - simple explanations of standards that you use all the time but don't need the originals; you just need to understand how to use them. We'll cut out all the fluff and give you the info you need.

But wait - can the FOA create standards? And what is a standard anyway? Here is the definition by the world's biggest standards organization:

ISO/IEC Guide 2:1996, definition 3.2 defines a standard as:
'A document established by consensus and approved by a recognized body that provides for common and repeated use, rules, guidelines or characteristics for activities or their results, aimed at the achievement of the optimum degree of order in a given context'.

Well, that certainly sounds like what the FOA is doing! As you all know, FOA certification is now internationally accepted and our technical references the first choice for unbiased, technically correct information on fiber optics and premises cabling. It's certainly logical that we would next try to put some order in the chaos of current standards. FOA standards are developed by FOA members whose expertise is in the technical areas covered by the standards and whose field experience in the industry contributes to FOA standards being accurate, relevant and current.

FOA now offers standards for testing the installed fiber optic cable plant, patchcords and cable, optical power from transmitters or at receivers and OTDR testing. Look for the "1 PageStandard" web page and in the FOA Online Reference Guide.

2012: The Year of The OTDR

Most of the technical and testing questions we get here at FOA involve misunderstanding of OTDR testing. A number of FOA master instructors have suggested we focus on OTDR training, both in our schools and online, to minimize the problems, so we have declared 2012 "The Year of The OTDR." Look for special articles, a new  "1pStandard" and other information that will make these instruments less enigmatic!

OTDR Tip Of The Month:
Why Should You Not Use "AUTO-TEST" On An OTDR

Some OTDR manufacturers tell you their instrument is smarter than you are so all you need to do is to attach the instrument to the cable plant you want to test and push the "AUTO-TEST" button - let the OTDR do the work.

Well, the trace below was sent to us by a frustrated customer who was give a bunch of traces like this from an installer to "prove" the installation was done properly. He called the FOA and asked us "what does this mean?" After we stopped laughing, we told him we doubted the installer had a clue what he was giving the customer. Then we explained what the trace meant.

OTDR AutoTest Problem

As you can see, the installer at least used a launch cable long enough for the test but did not use a receive cable on the far end to test the connector on that end. The OTDR could not resolve the 75 foot long cable under test (about 23m) at 1300 nm, indicating a gain of 0.39 dB on that fiber due to the interference of the overload at the first connector. Reflectance overload affects both traces as you can see, leaving us to also suspect the loss of the first connector on the 850 nm trace. However, that did not stop this OTDR from saying that this cable was a "PASS" - 5 times no less!

Out of curiosity, we asked the OTDR manufacturer why this happened. We were told that this unit would "PASS" anything unless the operator changed the limits.

Many of the technical questions we get here at the FOA deal with OTDRs and many are problems caused by untrained operators expecting the OTDR to do the trace interpretation for them. That is almost always a recipe for disaster!

If you are going to use an OTDR, learn how to use it first. Start with the new Fiber U OTDR self study course, "Understanding OTDRs".  You can also download the Free FOA  OTDR Simulator to practice analyzing traces.

Fiber = Energy Savings In Premises Cabling

Fiber has always been a tough sell in the premises cabling business where over a century of copper wire has made its use as much a tradition as a technical choice. But what happens when you analyze the energy use of a centralized fiber network versus a traditional copper network? Cirrant Partners, a NY IT infrastructure consulting and engineering company has done just that and issued a report on their findings. Here is how it starts:

"The total IT energy consumption in the US in 2011 is estimated to be slightly more than 100 Billion kWh2. (This is based on the energy consumption being 80% of the 2007 projection.) The actual consumption may be lowerdue to the economic times. Energy costs vary per state and usage classification and contract agreements. At a commercial national average price of 10.77 cents per kWh,3 the total IT energy consumption cost is estimatedto be $10.77 Billion. Annually, Billions of kWh of IT energy go unmonitored and largely unmanaged. A large part of the consumption is inefficiently-used energy by local area networks and supporting infrastructure"

Free FOA iPad App Calculates Loss Budget

The FOA has just released its second APP for the iPad/iPhone/iPod Touch, a free "loss budget calculator," FOA LossCalc.

FOA LossCalc
FOA Loss Calc App Screen

FOA 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.

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.

Fiber U
Two New Free Fiber U Self-Study Programs on Outside Plant Fiber Optics and OTDRs
There are two new free online self-study programs on Fiber U.

"Outside Plant Fiber Optics" uses the new FOA textbook and online reference guide to OSP to help you learn about OSP fiber networks.

The "Understanding OTDRs" self-study program will help you learn how to properly use these complicated instruments and there is a free OTDR simulator you can download to use for practice.

FOA Certification On Outside Plant Fiber Optics
The FOA CFospT outside plant certification focuses on OSP fiber optic network design, installation and maintenance. 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 knowledge 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.

Good Question! Tech Questions/Comments 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 or the video now on YouTube.

Municipal Fiber Network Advice 2/12
I am charged with researching a municipal requirement to install fiber optic infrastructure in new development--this could either be for active development or dark fiber for future connection.  Any pointers as to where to look?  Have any communities done this well....  done this poorly....  have good examples of policy, legal code or standards?
A: Municipal networks are becoming very common. The best example I know is Santa Monica, CA Citynet http://www.smgov.net/departments/isd/smcitynet.aspx  and we've interviewed them on the project.
Santa Monica built a citywide network to combine connections to all the city offices, public safety offices, libraries, etc. plus added numerous CCTV surveillance cameras, smart traffic signals and muni WiFi. They installed lots of fiber - fiber is cheap but installation can be costly, so they built a big network with lots of dark fiber in the beginning. Then they leased fiber to the local CATV company, Verizon for FiOS fiber to the home, and connected up dozens of tech companies to high speed Internet access (Google, Yahoo and dozens of movie production houses are located in Santa Monica.)
The really good deal was it paid for itself. Federal money helped with the initial installation (DoTransportation, DoEducation, Homeland Security) and leased fiber keeps the income coming.
As  a big college town already involved with "Gig U" (http://www.gig-u.org/), you should contact the people at the University to see what they have planned that may be able to be combined with your work.
I suspect that every town has its own issues with policy, codes and standards. We've discussed some of the issues with other towns and one thing that comes up regularly is that at a minimum, the town should own the conduits even if the fiber is private. If a private contractor digs up the streets to bury cables they should be required to install many conduits for whenever another company wants to pull cable, the conduit is ready and no digging will be necessary. We also suggest talking to the local telephone and CATV companies. In the past, many have fought muni fiber but now many cooperate with the city and lease fiber from them.

Help On Termination 2/12
I'm working as an user and sometime I install connectors on fibers. Most of the time I work with ST connectors. Do you have a small guide how to prepare, and polish the fibers ? Is it possible to use ST single mode connector on Multimode fiber and viceversa ?
A: We have several links that help you:

YouTube Videos:http://www.youtube.com/playlist?list=PL21F27A040DFAA6E5&feature=plcp
Tutorial: http://www.thefoa.org/tech/ref/termination/Term/Term.htm
Step-By Step Virtual Hands-on Termination:  Epoxy/Polish, Anaerobic, Hot Melt
Singlemode fiber termination, Hands-on SM termination
Even more from the FOA Online Reference Guide: http://www.thefoa.org/tech/ref/contents.html#Components

Singlemode connectors have tighter tolerances and a slightly smaller hole in the ferrule. Generally speaking, you can use SM connectors on MM fiber, except when the fiber diameter is on the high side of tolerance but you should never use MM connectors on SM fiber as the fit will be sloppy and the resulting core offset causes high loss.

Removing Unused Cables 2/12
Can you point me in the direction of information on how to properly and safely remove 50 Micron Multi-mode Fibre Optic Cable from a data center?  My company would like to remove their old FOC when they upgrade to 10g cable fibre and were considering cutting the LC connectors off the cables to make it easier to pull through the rats nest of cables under the floor.  Is this a safe method?
A: There is not standard way to remove cables, as it will depend on the installation. Cables in underfloor (or overhead) trays tend to be enmeshed in other cables unless they are in separate ducts. Under any circumstances, the best way to remove them is to cut off connectors, locate the cables and cut into lengths that are easily removed (just make sure you are cutting the right cables - a installer doing this with some cables in Newark, NJ once cut the wrong cable and put Wall St. out of business for a day!). Once they are cut into short lengths, it should be easy to remove them.
After removal, the cable can be recycled for the plastic - connectors are trash. Or if they are long enough, I may know some schools who would like them for their hands-on labs!

Higher Loss At Long Wavelengths? 1/12
Q: I have a tech in the field that has installed a piece of single mode fiber approx. 650’ long. He is testing it with a source and meter. The fiber is passing the 1310 loss test but failing the 1550 test. What could be causing this? He has put new ends on the fiber already and is getting the same results.
A: This sounds like a classic problem of cable stress. Singlemode fiber is much more sensitive to bending stress losses at 1550nm than 1310nm. If there is a stressed area in the cable installation, it's easy to get >3dB loss from a tight bend or kink, even near the connectors. There should be no difference with the connectors themselves. Telcos test links at 1625nm for stress testing.
Followup: The tech went back to the job site with an OTDR and found there was a spike in the reading about 120’ from one end which is where there is a pull box up in the ceiling.

Which Adhesive For Termination? 12/11
Epoxy, Hotmelt, and Anerobic
Adhesives - why each is used in in what situations. 
A: Epoxy/polish are used where highest yield, lowest cost and max reliability are needed. They are used for all factory made patchcords and a reasonable percentage of field terminations. The downside is they require an oven to cure the epoxy quickly. I actually invented a AC/battery-powered oven for use in the field that is still available - http://www.afsi.us/product.php?product=CURING to simplify the field use of epoxy.
Anaerobic adhesive is used when you are looking for low cost and fast field termination. You can use it with an "accelerator" solution that gives practically an instant set to the adhesive but with some loss of strength/reliability. We developed a method with no accelerator that the Navy uses because it's more reliable. The big difference with epoxy is the cured adhesive does not have a drop (epoxy bead) on the end of the ferrule that makes polishing virtually foolproof.
HotMelt (a 3M product) has the adhesive already inserted in the connector, so you just heat the connector up, take it out of the oven and insert the fiber. As soon as it cools, it's ready to polish. It has the adhesive bead on the end of the ferrule so polishing is easy. Against it is cost ($5/conn vs $1/conn for epoxy and anaerobic connectors) with essentially the same labor cost, a very hot oven (twice as hot as epoxy) and the need for AC power on site.

Some years ago, we did a study of termination times and here are the results: http://www.thefoa.org/tech/ref/termination/TerminationTimes.pdf

More On "Encircled Flux" - Maybe The Mandrel Wrap is "Good Enough" 12/11
IEC 86C/1004/DTR is our for comments and due to be be voted on next Spring, which by standards time is pretty quick! Here is the official description:
"IEC/TR 61282-11 Ed. 1.0   Fibre optic communication system design guides - Part 11: Multimode launch conditions
This technical report is intended to show the background of encircled flux for the characterisation of multimode launch conditions. This includes the selection of the encircled flux and the definition of the encircled flux requirements in conjunction with the implied variation in attenuation measurements."

Lines 490-492 from the draft document say it matches VCSEL launch conditions considered in 10 GbE. Lines 493-395 say it is close to the mandrel wrap mode conditioner used in TIA standards for many years.

That is a very useful conclusion.

ISO Mandrel Wrap OK

That's Why They Call Them "Dust Caps"
Q: We clean a connector, inspect it to ensure it is clean then put the dust cap on. If we inspect it after we remove that dust cap, it's dusty again, we assume from dust in the cap. I have tested different types and makes of dustcaps for the LC and clean ones are rare. If you only push them on half way it helps.....sometimes, but not always.  Does any company make clean (guaranteed) ones?
A: I've been saying for years that the reason they call them "dust caps" is they contain lots of dust. I know of no clean ones. Think about how they are made in millions and dumped in big bins in a factory! You just have to clean connectors when you remove them. Have you tried some of the dry cleaners? They seem to work well.

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! More on cleaningSee Product News below for links to vendors of fiber cleaning products.

See news about
Fiber Optic Cleaning Videos on YouTube by ITW Chemtronics below.

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.

Fiber Optic Cleaning Videos on YouTube
ITW Chemtronics has three fiber optic cleaning videos on 
videos covering Dry CleaningWet-Dry Method, FiberWash and Combination Cleaning. They are good explanations of cleaning processes - the Wet-Dry is especially interesting.

Should You Use Dry Water-Blocked Cables Near Salt Water?
Here's another controversy in the fiber optic business. It seems that some dry water-blocked cables have problems with salt water affecting the speed and amount of water absorption by the super absorbent powder (SAP seems to be a new industry TLA - that's "three letter acronym" - for super absorbent powder) used in these dry water-blocked cables (DWB?). It seems that salt water performance has caused some users to not use this cable anywhere that it may encounter salt water. But according to an article by Ryan Chappell of Coats, a manufacturer of the yarns used in fiber optic cable manufacture as well as SAP, there are big differences between the absorbency of materials from different suppliers. We suggest you 1) read the article in Lightwave, 2) check out the Coats website and 3) ask your fiber optic cable manufacturer about their cable before installing it in a salt-water environment.

We're Part of A $trillion Industry in the US
A TIA commissioned report on “The Contributions of Information and Communication Technologies to American Growth, Productivity, Jobs and Prosperity,” (written by Robert J. Shapiro and Aparna Mathur, August 2011) finds that “ICT companies accounted for 3,535,000 jobs in 2009.” The report states that “in 2009, ICT firms contributed about $1 trillion to U.S. GDP, or 7.1 percent of GDP.  This total includes nearly $600 billion in direct contributions from their own operations and more than $400 billion in indirect contributions through the benefits other sectors derived from the use of ICT.”
Other highlights from the report include:
“The President’s proposal to fund the development and initial deployment of a nationwide wireless broadband data and communications network for public safety agencies would lead to the creation of an estimated 100,000 new jobs in ICT industries and, over time, produce indirect or spillover benefits of an estimated $4 billion to $8 billion per year.”
“Investments of $3.4 billion in a “Smart Electricity Grid” under the 2009 Recovery Act should directly produce nearly 30,000 new jobs.  If the funding becomes seed money and an ICT-based Smart Grid is developed and deployed, analysts estimate the net economic benefits could range from $48 billion to $76 billion per year.”

FOA Tech Topics - 
A Fiber Optic Tester In Your Pocket?  (See the video on Corning on YouTube )
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.

    Download This!
    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. 
    Download yourself a copy and read it! http://lw.pennnet.com/whitepapers/wp.cfm?id=665
    Westover Application Notes And Cleaning Video
    Westover has several application notes on inspecting and cleaning fiber optic connectors. The video is a big file (50+MB) but a good tutorial.

    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.

    Jobs Created As Part of Stimulus-Funded Projects
    The federal government is spending 7.2 billion dollars on the Broadband Technology Opportunities Program.  This money is working it's way into the economy and hopefully will provide jobs.  You can track recovery dollars and look for job opportunities on this website:
    www.recovery.gov  Go to "opportinities" link then "jobs".  You will see a section “find recovery jobs” – enter “fiber optic jobs California” or wherever you are and review what comes up.

    One of the projects funded by stimulus money is the 1100 mile network of
    Maine Fiber Company Inc. which has selected nextGen Telecom Services Group Inc. as the installation contractor. CFOTs: NextGen has a link on their website for applying for jobs

    FOA Certification Top Choice

    The FOA CFOT and CFOS programs continue to gain momentum in fiber optics. Over 36,000 CFOTs (December 2011) have been certified by over 250 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 in place 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.

    To answer questions on FOA certifications, we have several web pages:
    Overview of FOA certifications
    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!
