More Than 100,000 FOA Certifications

ribbon splicing
Ian Gordon Fudge of FIBERDK teaches ribbon splicing on a high fiber count cable (see additional photo below)

FOA keeps track of the number of individuals we have certified each month and puts that in a graphic you will find in the left hand column of this newsletter and on several other pages about FOA certifications. Of course, we also have a database of every person who has taken an FOA certification, so we can look up anyone who has had an FOA certification since the FOA started 24 years ago. This month while we were updating our database of those who have FOA certifications, we noticed how many of those individuals had also received other certifications. So we searched our database and were surprised at the results.

FOA has more than a dozen specialist certifications with splicing, testing, premises cabling, design, outside plant (OSP) and fiber to the home (FTTH) being the most popular. We searched our database and found out that FOA has granted over 102,000 certifications to the 77,000+ individuals who hold FOA certifications. Many of our CFOTs and CPCTs have taken additional training either through FOA approved schools or through our Work-to-Cert program and qualified for these specialist certifications.

FOA is continually updating the materials in our certifications and references like the FOA Guide and courses on Fiber U to keep them current. We've just updated splicing and connectors, for example. If you want to upgrade your skills and get certified, look at the FOA specialist certifications.

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


High Fiber Count Cables

We've had a continuing feature on high fiber count cables in the FOA Newsletter and we now have some interesting photos to show you. Corning generously sent FOA some samples of 1728 and 3456 "RocketRibbonTM" cable. We took some photos and must admit that these cables are fascinating updates on the traditional fiber optic cables.

high fiber count cable


Here are Corning RocketRibbon 1728 fiber (bottom) and 3456 fiber (top) cables. To get an idea of these cables size, look at this photo:

cable

The 3456 fiber cable is 32mm diameter, 1.3 inches. The 1728 fiber cable is 25mm, 1 inch diameter.

These are cables made from conventional "hard" ribbons, not the "flexible" ribbons used on some cable designs. As a result of using hard ribbons, the fibers are arranged in regular patterns to get high density.

cable

These are the tubes of ribbons from these cables. Each of those tubes of ribbons has the equivalent of 24 ribbons of 12 fibers each (actually 8 X 12 fibers and 8 by 24 fibers stacked up) for 288 fibers total. The 1728 fiber cable has 6 tubes and a center foam spacer, with 144 ribbons total. The 3456 fiber version has 12 tubes and no spacers, 288 fiber ribbons total.

What amazes us is the density of fibers.

cable

We calculated the "fiber density" of this 3456 fiber cable based on 200 micron buffered fibers and determined that 54% of the cable is fiber. Compare that to a typical 144 fiber loose tube cable, which is about 14% fiber or a 144 fiber microcable which is about 36% fiber.

Looking at the end of this cable reminded us of nothing so much as this PR photo from AT&T from their intro of fiber in 1976:

cables

Not the fiber, the dense cable of copper pairs!

Of course the cable is much lighter than copper but much heaver than you are used to with fiber - it weighs 752 kg/km or about 1/2 pound per foot. And it's stiff. Very stiff. The minimum bend radius is 15 times the cable diameter or 480mm (~19 inches), about a meter or yard in diameter.

As we noted in the photo above, Ian Gordon Fudge of FIBERDK taught some data center techs how to handle a 1728 fiber Sumitomo cable with a slotted core. Ian sent FOA this photo to illustrate the number of fibers in the cable he was using for training. Impressive!

Fiber DK

Here is the slotted core that separates the flexible fiber ribbons
in the Sumitomo cable:

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

This months "Good Questions" has some unique questions from our readers.



We Were Going To Cover Several More Topics This Month But Could Not Read The Literature

(This Is Important Feedback To Suppliers)

(Commentary by your editor, JH)

We were going to cover several more topics this month, the future for 10G PONs for FTTH, 5G indoors, cabling for data centers, all using information from major manufacturers. We downloaded or received in the mail literature on all these topics during the month.

But when it came time to read these documents, we had to give up. We think the content might have been good but we could not get through any one of them. Why? Graphic designers. Every one of these companies used the latest "cool" trend in publishing: grey type instead of black and sized smaller than some type we've seen on contract disclaimers and insurance policies, the usual things we blame for having the most unreadable type.Reading these materials with difficult and tiring or just plain impossible.

We tried everything. Magnifying glasses, enlarging type on the computer screen, brighter lights. Nothing worked. Here is an example of the type on a diagram we were trying to figure out, after we enlarged it to try to read it:

Whazzis?
Can you interpret that?

To all manufacturers, distributors, writers, graphic designers and publishers: IF WE CAN'T READ YOUR LITERATURE, YOU ARE WASTING YOUR MONEY AND OUR TIME!

And what I could read often left me befuddled. For those of you not familiar with American slang, befuddled is a bit like confused or not able to think clearly. I literally read terms like "actionable intelligence," "hyperbolic visions," "parallel technologies" and my favorite, "disruptive analysis." Yecch....

 Dealing With High Fiber Count Cables - Continued Updates

We ran this first in the March 2019 FOA Newsletter and asked for feedback. We have some feedback and have been talking to people in the industry also. We thought we'd share some of what we've been told and see if others agree. Feel free to comment!

High Fiber Count Cables may not be for everyone. Maybe only for a very few. A single cable that has as many fibers as 12-144 fiber cables (1728 fibers) in a cable with a diameter of only twice that of a conventional 144 fiber cable can present challenges.
  • First of all, the cost - it's high. Fiber may be inexpensive but with so many fibers, the cable becomes expensive. You do not want to waste cable at this price. Engineering the cable length precisely will save lots of money.And it's worse for higher fiber counts.
  • Likewise, making mistakes when preparing the cable for termination can be expensive.
  • The cable may require special preparation procedures to separate fibers for termination. Most use new methods of identifying cables and bundles.
  • Besides skill, the tech working with high fiber count cables needs lots of patience.
  • Splicing multiple cables at a joint can get complicated keeping all fibers straight.
  • These cables will generally use 200 micron buffered fiber and often a flexible ribbon instead of a typical rigid ribbon structure to reduce fiber sizes. This may complicate splicing as the methodology to splice the flexible fibers and splice 200 micron fibers to regular 250 micron fibers is a work in progress.
  • Splicing 200 to 250 micron fibers may be easier with the flexible ribbon designs which make it easier to spread fibers to the same spacing.
  • We've heard the splicing time for flexible ribbons is about twice that of conventional rigid ribbons. So if you use that table below, you may need to double your ribbon splicing estimates when working with flexible ribbons.
Agree? Disagree? Comment?

ORIGINAL Article: March 2019

FOA has recently gotten several inquires about these new high fiber count cables - 1728, 3456 or even  6,912 fibers. Like this one from Prysmian with 1728 fibers:

Prysmian 1728 fibers

We've been looking for directions on how to deal with high fiber count cables. Several contractors tell us ribbon splicing is the way to go, and most of these cables now use a version of the new ribbon types that are flexible. We've  put together this table from some articles on splicing ribbons:

Is that realistic? We've heard the flexible ribbons may take twice as long as the conventional ribbons.

Ideal Introduces A PoE TESTER - PoE Pro

PoE

We've written many articles about PoE in the FOA newsletter and often lamented the lack of testers. Ideal is now offering a solution. The new Ideal PoE Pro eliminates guesswork when installing, maintaining and troubleshooting networks where PoE is deployed. Previously technicians had to understand all the various standards, device power outputs and cable lengths to be sure a device will operate successfully. The PoE Pro identifies the Class of the PoE source and power available to a PoE device regardless of cable length, cable quality or other factors.

  • Supports PoE up to 90W (PoE++)
  • Test all PoE Classes (0-8) and Types (af/at/bt)
    Identifies the powered pairs
  • Helps to determine PoE switch or mid-span injector
  • Accurately measure the maximum power available
    Verify the PoE installation Pass / Fail indication to IEEE standards

FOA Guide


We are continually updating the Online Reference Guide to keep up with changes in the industry and adding lots of new pages of technical information. When you go to the FOA Guide Table of Contents to see the latest updates - look for New.

FOA Guide Adds And Updates More Pages

 On Jargon, Restoration, Fiber Characterization And Management

The FOA Guide is a living thing, growing bigger and better continuously, updated for new technology and techniques, aimed at keeping the world up to date on fiber optics and cabling. In the last month alone, the Guide has added three new sections you should find interesting, informative and helpful and updated a couple more.

Fiber Optic Jargon - Illustrated

FOA has always believed that jargon is important - it's the language we use - and fiber optics has a lot of its own language. As you have probably noticed, Chapter 2 in all our textbooks is "Jargon." That chapter gives an introduction to the language and helps get the reader familiar with the terminology before they delve into the rest of the book. This month, we updated all the jargon pages to include dozens more photos and drawings - animations too - that make it even easier to understand fiber optic jargon. Take a look at Basic Fiber Optic Jargon, OSP Fiber Optic Jargon and Fiber Optic Jargon for managers.

Fiber Optic Restoration

All networks are susceptible to problems that affect communications. A consequence of fiber optic systems’ high bandwidth, long distance capability and security is the extreme dependence of users on the non-stop operation of these systems. They can transmit large amounts of data long distances with immunity from signal degradation and extremely high reliability, so these systems usually carry the most critical data. If something happens, it’s important to not panic. You should have a plan, components set aside for repair and knowledgeable people on stall or a contractor on call. When you design the network, restoration planning should be part of the design. If you did not do that, now is the time to do it before something happens. FOA has a new page on Restoration in the FOA Guide that provides advice for everyone - contractors/installers, network owners and managers - everybody who gets involved when the network goes down.
 

Fiber Characterization

As networks get faster and link spans get longer, fiber characterization becomes more important to he network owner and contractor/installer. Chromatic dispersion, the dispersion caused by light of different wavelengths, and polarization mode dispersion, caused by the polarization of the light in the fiber, become factors limiting the bandwidth capacity of fiber links. Pulse broadening due to dispersion and the variation of fiber attenuation with wavelength can become issues with DWDM. All these factors need testing on long distance networks to ensure proper link performance. Tests are performed on new installations to ensure the fiber being installed is capable of future upgrades. Older cable plants are tested to evaluate fibers for upgrades of legacy communications systems at slower speeds. We've created a certification program for fiber characterization, CFOS/FC, but not many FOA schools have the equipment to teach the course. In addition, we've had requests for a course for managers, not technicians, who don't need to know how to perform all the tests but do need to know what the problems are, what fiber links need testing and how to find competent contractors to do the work. The updated Fiber Characterization page in the FOA Guide goes in to more depth on why fiber characterization is important, what tests need performing and how to interpret results.

Fiber Optic Testing

Practically every page in the section of the FOA Guide on Fiber Optic Testing has been reviewed and updated, much of it based on the new FOA textbook on testing. This includes pages on measuring power, fiber attenuation, connector or splice loss and cable plant loss. Browse through the testing section and see what's new.

Fiber Optics For Managers

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

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


The FOA Guide to OSP Construction

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

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

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

The FOA Guide to OSP Construction


FOA Guide on Inspecting and Cleaning Connectors.

Dirty connectors are one of the major problems in fiber optics, causing high connector loss, high reflectance and contaminating transceivers. Network operators claim that 15-50% of all network problems can be traced to dirty connectors causing connection problems.

Troubleshooting With A VFLFibers Damaged In Splice Trays

Is this a trend? Twice in one week, we have inquiries from readers with problems and both were traced to fibers cracked when inserted in splice trays. The photo below shows one of them illuminated with a VFL. This was the same issue we found in the first field trial of a VFL more than 30 years ago that led to its popularity in field troubleshooting.

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

Yokogawa Releases OTDR for Rapid Testing of PON Access Networks

Yokogawa AQ1210 OTDR
AMERSFOORT, THE NETHERLANDS — The new Yokogawa AQ1210 OTDR (optical-time domain reflectometer) only resembles the existing AQ1200 in appearance - internally it has been completely re-engineered to bring the features and user-friendly operation of the AQ7280 flagship OTDR to the installers and testers of passive optical networks (PON) and fibre to the antenna (FTTA).

PON is typically used throughout the world to provide optical fiber-based services to domestic and commercial customers. With 6 models offering 2 or 3 wavelengths, and the ability to test live fibre networks with high-port count splitters (up to 1:128), every user can find an AQ1210 model with the combination of wavelengths required to meet the testing needs of their local country or region.

Recycling Fiber Optic Cable

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

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

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

Safety On The Job

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

Investigators Eye Fiber Optic Work in Deadly Wisconsin Gas Explosion

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

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

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

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

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

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

FOA Facts

FOA is a non-profit professional society chartered to promote professionalism in fiber optics through education, certification and standards. FOA is mostly known for  certifying techs - mostly CFOT®s -Certified Fiber Optic Technicians - but also may be CPCTs - Certified Premises Cabling Technicians or corporate members involved in fiber optics.

FOA is a "virtual organization" - we have no "brick and mortar" presence. We operate over the Internet with operations centered in California, with active workers and volunteers in locations as diverse as Texas, Ohio, Canada, Singapore, Malaysia, Denmark, South Africa, the Middle East and many more.

Being a virtual organization, FOA has very low overhead, allowing us to offer cost-effective certifications and many free programs to support our industry.

CFOT Total
As of today, FOA has certified this many techs. About 90% come from our schools but many experienced techs have become FOA CFOT-certified directly through our "Work-to-Cert" program.

FOA has almost 200 approved training organizations in about 40 countries around the world around the world.

FOA Certifications Now Last For 3-Years

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

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

FOA CFOT Logo

FOA has 14 fiber optic certification programs covering every aspect of fiber optic network design, installation and operation.

Primary Certifications: CFOT (basic fiber), CPCT (premises cabling), CFOS/O (outside plant, taught with CFOT included) and CFOS/D (fiber optic network design).

Skills Certifications (for installers and techs, requires CFOT): CFOS/S (splicing), CFOS/C (connectors/termination), CFOS/T (testing), CFOS/FC (fiber characterization).

Applications Certifications (for techs or anyone, including managers and supervisors): FTTH (fiber to the home), CFOS/L (optical LANs), CFOS/DC (data centers), CFOS/A (fiber to the antenna), CFOS/DAS (distributed antenna systems) and CFOS/W (fiber for wireless)



(what you are reading)

FOA monitors the trade press, websites and other resources continually to look at what's happening in many technologies that affect fiber optics. We're tracing technologies as diverse as wireless, IoT, autonomous vehicles, smart cities, energy, or anywhere fiber is used to bring news to our readers.

FOA continually updates our technical materials, online and printed, and our curriculum to ensure our readers have access to the latest technical information and our schools teach the latest technology and applications. Our printed books are being updated right now.

FOA Guide
FOA created the FOA Online Guide as a non-commercial trustworthy technical reference almost a decade ago so the industry would have a reliable technical reference. In the last year, over 1million visitors downloaded about 4 million pages of technical information.

fiberu.org

FOA offers free online self-study programs at Fiber U. In 2017, the number of online sessions doubled to 200,000. Many of those 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.

videos

FOA offers over 100 educational YouTube videos that have been viewed 2.4 million times.

FOA offers its training programs to other organizations at no cost to help them train their members properly in fiber optics. For example, FOA has been working with the Electrical Training Alliance (IBEW/NECA) for over 20 years, training their instructors for their apprenticeship programs. We work with many other organizations and companies to provide the materials they need.

FOA has about 300 corporate members - companies in various aspects of the fiber optic industry worldwide that we list online and offer discounts on certifications and renewals.

FOA provides speakers for many conferences and even presentations for use by other organizations to educate people on the aspects of fiber optic communications.

FOA has a program to provide
classroom materials for STEM teachers (science, technology, engineering and math) introducing K-12 students to fiber optics and creating science projects.

FOA provides forums for discussion on various social media. Our LinkedIn groups have about 5,000 members each. If you are not joining us on social media yet, please do.

Interested In A Career In Fiber Optics?

Careers in fiber optics


FOA has created a new YouTube video to introduce students to careers in fiber optics. It was made for showing to high school and junior high students interested in tech careers but anyone interested in a possible career in this field will find it interesting. If you have kids in school or know teachers, let them know about this too. Watch the FOA Careers In Fiber Optics Video on YouTube and visit the
FOA Careers In Fiber Optics web page at www.foa.org/careers/.

Fiber Optic Education For Students At Any Age 

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

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

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

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

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

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

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


Resources For Teachers In K-12 And Technical Schools

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

 

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






Should Your Company Become An FOA Corporate Member?

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

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

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

FOA Corporate members

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

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

How Does An Organization Become An FOA Corporate Member?

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

Lennie & Uncle Ted Guides - Perfect For Getting Started

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

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

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


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

FOA iPad Apps

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

Feedback

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


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

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

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

Good Question! Tech Questions/Comments Worth Repeating

New: The FOA Fiber FAQs Page (FAQ s = frequently asked questions) gathers up questions readers have asked us and adds tech topics of general interest.

Real Questions From FOA Newsletter Readers

Testing Cable Before Installation
Q: Does the FOA publish a standard for assessing single-mode fiber optic cables, prior to use on a specific project?
A: The ANSI/NECA/FOA-301 fiber optic installation standard covers this in Section 4.1. It recommends visual inspection and testing if there is any suspicion of damage to the cable. Many contractors will test a couple of fibers with an OTDR before installing any cable, just for assurance. It requires an OTDR with a pigtail launch cable and a mechanical splice.


Cable Bend Radius
Q: We are working on project where we need to know difference between short term and long term bend radius for fiber optic cable?
A: The bend radius for cables is generally specified under two conditions - under stress, e. g. when being pulled, it is a radius 20 times the cable diameter. Relaxed, after installation, it is a radius 10 times the cable diameter. The relaxed specification, 10X, is considered a long term specification. Some of the new high fiber count cables have different specifications, sometimes 15X or 20X under either condition. Check with the manufacturer for their specific cable.

OTDR Resolution
Q: 
If testing a 40KM link with 1KM launch and receive cords should I be able to see the connector and cassette splice on each side? My OTDR setup is at 64KM, 300ns pulse and 10 second test at 1310/1550/1625. It shows as a single event so far but with the pulse width at 300ns won’t that combine the events into one event during analysis?
A: You will not be able to resolve a connector and splice close together, especially on a long link like that. 300ns is almost 60m pulse width! You will see an even of the splice and connector combined.


Transmission Wavelength Compatibility
Q:
We are looking at the specs for  two devices, A and B. The spec sheet of Device A lists it is capable of MM in 850nm wavelength. The spec sheet of Device B lists it can do MM at 1300nm. If I connect these devices via MM patch cord, what is the impact due to different wavelengths? Will the transmission suffer significant loss or since both are multimode, wavelength is irrelevant?
A: Fiber works at either wavelength, but transceivers do not. The attenuation rate for MM fiber is ~3dB/km at 850nm but only ~1dB/km at 1300nm. But  850nm receivers use silicon photodiodes while 1300 nm receivers use InGaAs. The 1300 detectors are not sensitive at 850nm and vice versa. So while the fiber works fine, the electronics do not. They should only be used with like devices.

 



Older questions are now available here on the FOA Guide.

FOA "Quickstart Guides"

In our continuing quest to help people understand how to test fiber optic cable plants and communications systems, we've created two more "QuickStart Guides to Fiber Optic Testing." They are simple, step-by-step guides on how to test fiber optic cable plants, patchcords or single cables using insertion loss or OTDR techniques and optical power from transceivers. It's as straightforward as it can get - what equipment do you need, what are the procedures for testing, options in implementing the test, measurement errors and documenting the results.
It can't get much simpler.

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

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

YOKOGAWA OTDR Has Extended range, High Resolution And Multitasking


Yokogawa OTDR

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

FOA thanks Yokogawa for a gift of an OTDR to use for R&D and teaching!

Where Are The Jobs In Fiber Optics?

Fiber Optic Installation Banner

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

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

What Training Is Needed For The Jobs In Fiber Optics?
As you will learn from the video described above, the jobs in fiber optics are quite diverse. FOA has investigated these jobs to understand the needs of workers for those jobs and, when necessary, create curriculum and certifications to properly train workers. For example, the FOA FTTx certification was developed at the request of Verizon who needed specialized installers for their FiOS program. Now we are working with the industry on the OLAN (Optical LAN) program (see below).
We have summarized the jobs and required training in a new web page that has two uses - 1) If you have FOA certifications, what jobs are you specifically qualified for? - 2) If you are working in a specialized field or want to get a job in that area, what training and certifications will qualify you for those jobs?

How To Find And Apply For Jobs In Fiber Optics
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.
If you are looking for a job in fiber optics, here is the FOA's guide to jobs. 

We hope you find this useful. FOA tries to find new to increase the professionalism in our industry and helping qualified people find jobs is our highest priority - read the article below to see why! If you have feedback on how we can help you and our industry, contact us at info@thefoa.org.
