|2009: What To Expect?
Forty years ago I attended a training session given by Oliver Wight, the IBM employee who invented MRP systems. (materials requirement planning). The first thing he covered was forecasting, and he reminded us of the one thing one must never forget about forecasting: "All forecasts, from the moment they are made, are wrong!" Having never forgotten this, I am reluctant to make forecasts or, when forced to do so, repeat Ollie's warning! So consider yourself warned....
That said, I do want to share with you some thoughts on what we hear and see for the coming year. First, the economy is not likely to improve in the short term. It may get worse, even much worse. After the last telecom bubble burst in 2001, some companies failed quickly, others struggled until acquired and some have never recovered.
But the telecom market recovered over the last seven years slowly based on real applications and revenue, not the hollow promises of the "Dot Bomb Era." The dramatic reduction in the fiber optic market - and prices of fiber optic components - has been a major reason the focus of telco fiber has moved to FTTH (fiber to the home).
The other reason was the high cost of maintenance of aging copper cable plants that could not support newer services that generate good revenue like DSL for Internet or TV. Verizon, which probably has the oldest cable plants, justified their FiOS FTTH program in part on maintenance savings which would offset about 20% of the cost in only the first 4 years.
Now FTTH technology is proven, the major obstacle to its expansion is capital for installation and overcoming some regulation. For the last eight years, telcom oversight appears to have been more based on poitical ideology and lobbying than technology, but the new administration looks ready to change all that.
We look for the new administration to be full of technical whizzes not political wonks and the proposed government spending on infrastructure to pump up the economy to specifically target expanding broadband access:
Obama said his administration would seek to implement the "single largest new investment in our national infrastructure since the creation of the federal highway system in the 1950s" via use-it-or-lose it grants to states—and made clear that this would include digital infrastructure no less than roads and bridges. "As we renew our schools and highways, we'll also renew our information superhighway," said Obama. "It is unacceptable that the United States ranks 15th in the world in broadband adoption. Here, in the country that invented the internet, every child should have the chance to get online, and they’ll get that chance when I’m President—because that’s how we’ll strengthen America’s competitiveness in the world." See
Not only will fiber benefit from the expansion of broadband connectivity, fiber will be installed alongside highways, within towns as part of security and traffic management systems as part of metropolitan networks funded by economic recovery funds. Job retraining for broadband is also likely to be a focus of this new administration also, as their focus also includes jobless benefits.
What about fiber in corporate (premises IT and industrial) networks? As corporate backbones move toward 10G Ethernet, fiber has major advantages in speed, latency and power consumption, all three important issues for IT networks. But the cabling to the desktop is being dropped in favor of newer wireless technology, allowing workers the mobility they desire. Copper wiring is still suffering from volatile prices for copper and plastics used in cable construction also. Industrial networks will lag as production drops. But the biggest unknown factor in corporate networks is where will the money come from. Credit remains hard to get and corporate profits are dropping. Upgrades in corporate networks look less likely today.
During one recession, I worked for a company whose President was adamant that recessions were opportunities for growth. Rather than cut back R&D or promotion, he continued developing new products and selling as hard as he could. While competitors hid in their shell, the company gained market share and grew like crazy when the economy started to improve. That's what I advise if you can do it.
Jim Hayes, President
Broadband and Training on White House Agenda
Today, January 20, 2009, Inauguration Day, the Obama Administration posted its agendas on their website, including their agenda for technology:
You should read it for yourself - but we copy here two parts that we at the FOA are delighted to read:
Deploy Next-Generation Broadband: Work towards true broadband in every community in America through a combination of reform of the Universal Service Fund, better use of the nation's wireless spectrum, promotion of next-generation facilities, technologies and applications, and new tax and loan incentives. America should lead the world in broadband penetration and Internet access.
Lifelong Retraining: Reauthorize the Workforce Investment Act, and increase resources for community colleges and lifelong learning initiatives to ensure our citizens can continue to gain new skills throughout their lifetimes. Modernize and expand the existing system of trade adjustment assistance to include service sector workers hurt by changing trade patterns. Create flexible education accounts that workers can use to retrain.
Strangest Fiber Cut Ever?
This article appeared in the newspaper in the small town in Southern California where we live. A woodpecker twice penetrated an aerial fiber splice closure and broke fibers. Obviously the woodpecker thought it was something like a tree trunk, but I doubt it found the fiber as tasty as the bugs it's usually looking for!
Know any other strange causes of fiber outages? Let us know!
Here's You Chance To Own A Fiber Optic Training Company In Canada
Bill Graham, owner of Mississauga Training Consultants and member of the FOA Board of Directors from many years, is selling his training business. “I have operated Mississauga Training for almost 14 years,” says Graham, “but I’m past my mid-60s with some medical problems that are limiting my future activities. That is my reason for selling these businesses.”
Mississauga Training offers training and sells fiber optic tools, test equipment and some materials. “While these businesses go well together, they can also operate separately,” says Graham, adding that both are solid businesses with almost no competition. “For someone in the industry, this is a terrific business opportunity, and I would assist them to get started.”
Bill has promised to remain on the FOA Board of Directors and stay involved in helping us direct FOA activities.

FOA Online Fiber Optic Reference Guide "Tour"
Each month, we'll do a quick tour of part of the FOA Online Fiber Optic Reference Guide to show you what's there and how to use it effectively. One of the "tricks" we use in the Fiber Optic Reference Guide is what we call "Virtual Hands-On" tutorials." These are online slide shows that show you how do perform a standard fiber optic task like preparing cable, splicing or terminating with various types of connectors. They are developed only after analyzing tasks, breaking them into their logical steps and understanding the reason behind each part of the process. There are lots of VHOs in the Fiber Optic Reference Guide, so take a look at those of interest to you.

Good Question! Tech Questions Worth Repeating
Q: If I test a FO link from both sides, am I suppose to get the EXACT distance reading?
A Contractor is busy installing some FO systems. The OTDR result from one side show 14,5189 km and on the same fibre from the other side his machine gives a result of 14,5577 km... to me this is about 39 meters difference. I try and understand this.
A: Let's look at the numbers: The difference in readings is 14518.9 to 14557.7 or 38.8 meters. That's a difference of 0.27 percent. The resolution of the instrument is 0.1 m or 0.006 percent of the reading.
How does the OTDR measure distance of a length of fiber? It sends out a pulse and looks for the returned reflected pulse from the far end. It measures this round-trip time and divides it in half for the one-way time. It then multiplies that time by the speed of light in the fiber, defined by the effective index of refraction, something around 1.4675 (Corning SMF28, a typical fiber.)
The OTDR measurement depends on an accurate time measurement by the OTDR, knowing the speed of light in the fiber precisely and the techniques used to get and process that information.
What's the "accuracy" or "measurement uncertainty" of the instrument? Referring to the
+/-time base error x distance +/- 1m +/-sampling resolution +/-index uncertainties.
The time base error can be 0.01 to 0.001%
The uncertainty of the index of refraction is about 0.1% to 0.01%
For this example
+/- 0.001% x 14518 m = 14.5 m or 0.01% = 145 m
+/-sampling resolution =? probably a few meters?
+/-index uncertainties. = 145 or 1450 m
Adding these up, we have a measurement uncertainty of at least 14.5+145+1=~160 m or as much as 145+1450+1=~1600 m
And that's applicable for repeatedly measuring the same fiber. From two directions, there may be differences on how the measurement markers are placed if done manually.
So the uncertainty of a 14,518.9 length measurement (+/-160 to 1600 m) is much larger than the 39 meter difference the instrument gave for bidirectional measurements.
The answer to your question, therefore, is the difference in the OTDR length measurements is due to the error inherent in making the measurement with an OTDR.
We're surprised the results were so close!
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.
Q. Is it OK to use inexpensive air-gap attenuators with lasers in singlemode networks?
A: Since lasers are sensitive to reflectance and air-gap attenuators may have high reflectance, we do not recommend using them on singlemode systems. Filter type attenuators with low reflectance are recommended. Here's more on attenuators from our new Online Fiber Optic Reference Guide including a simple way to make an attenuator yourself.
We're covering these topics (and a lot more) in our new FOA Online Fiber

JDSU has announced the See the Light webinar series, a four-part program designed for anyone involved in the installation, maintenance, and repair of fiber optic systems. It begins with fiber inspection and cleaning and then covers the basics of fiber testing. The webinar series then continues with the more advanced optical time-domain reflectometer (OTDR) and fiber local area network (LAN) testing challenges.
Interested In Fiber Optic Sensors?
Besides it's uses in communications, medicine and lighting, fiber is used for sensors. It began long ago with fiber optic gyros and chemical or acoustic sensors but has expanded to many more physical measurements. Now there's a website

Market Analysis: Overbuild: The New RBOC Advanced Access Architecture Strategy?
Verizon is placing fiber cable for Advanced Access Architecture (FiOS) in AT&T franchise areas in north Texas. They expect to start offering service in these areas in direct competition with existing cable companies and AT&T late in 2008. This is probably the first time that the RBOCs have directly competed with each other in residential services. It may sound a note that can drastically change the industry.
In June of this year, the Texas PUC issued an order approving Verizon’s request to extend its “State-issued Certificate of Franchise Authority” to 12 new areas immediately outside Verizon’s Texas franchise and inside AT&T’s franchise. Shortly thereafter, they began extending fiber from their existing FiOS-equipped central offices to relatively nearby areas in these newly acquired franchise areas.
In recognition of the possible overriding importance of this development, Information Gatekeepers Inc. (IGI) has commissioned Clif Holliday to expand their group of reports on Advanced Access Architectures to include a new report on this overbuild activity. The new report, which will be out before the end of the year, is entitled "Overbuild: The New RBOC Advanced Access Architecture Strategy?"
