AT&T To Spend $17-18 Billion in 2009, Add 3,000 Jobs
AT&T Inc. has said it plans to invest $17 billion to $18 billion in its infrastructure in 2009 despite the recession and will add 3,000 new jobs. The carrier says it’s still seeing increased demand for mobility, broadband and video – and especially for mobility, with a veritable explosion in demand expected once the economy turns around. It wants to capitalize on what growth areas there are (wireless and IP). And it wants to be ready for the future.
“We expect demand will only escalate when the larger economy rebounds, and AT&T’s continued strong network investment will help ensure that we’re fully ready to support the next wave of economic growth said Randall Stephenson, AT&T chairman and CEO, in a statement. “We recognize the continuing importance of investing in critical network infrastructure, which plays a key role in driving commerce, innovation and job growth.”
AT&T said it will nearly double its U-verse residential fiber footprint, hoping to pass 30 million homes in 2011, up from 17 million today. The carrier will continue to expand its DSL reach as well to cater to those looking for “affordable broadband.”
It all adds up to AT&T expecting to see data traffic on its core network growing more than 50 percent year-over-year, so its global IP backbone is getting a cash infusion too, including investment in subsea fiber-optic cables.
What's Up At Google?
Last month we discussed the impending entry of Google into the telephone business. Clifford Holliday, a writer and analyst for IGI, has been working on a report on Google and telephone. Mr. Holliday spent many years as the VP in charge of technology planning in the Business Development department of GTE so he knows the telephone business. Here's his comments:
"In 2007, Google purchased a small startup called Grand Central. Grand Central provided a service that allowed calls to follow a user to different phones, and visual voicemail. In early March 2009, Google announced that it had now rebranded the service to Google Voice and added a number of new features. Early reporting on the features included free calling within the United States, extremely cheap international calling, and many advanced call- and phone-management capabilities. Although not yet available to the general public (it is said that it will be in a few weeks), the threat is clear. Google is indicating that it will give away the entire voice business (at least within the United States) just to get an added advertising platform. How big a market can we expect for Google Voice? Is this a threat to mainstream telephony? What are than main issues impacting the telecom market today?"
FOA CPCT Certification
What are people saying about the new FOA CPCT Premises Cabling Certification covering fiber/copper/wireless?
You have done a fine job, I found the test to be right on the money with today's need's.
Questions were geared to real world applications.
We needed this in the industry.
This is only one of the reasons FOA certification shines.
This is practical instruction for our industry.
While most premises cabling certifications only cover "Cat 5" unshielded twisted pair (UTP) cabling, the FOA CPCT covers premises cabling the way it is being used today - not ten years ago! Now most premises networks use fiber backbones, UTP cables to the few desktops now being used and cabling to wireless access points for laptops and other WiFi- connected devices.
Those who have experience in the field of premises cabling, even if they do not have a CFOT, can apply for the CPCT certification directly to the FOA. To facilitate preparing for the CPCT exam, the FOA has created the Premises Cabling section on the Online Reference Guide and created a CPCT Study Guide for the exam.
FOA Revises Advanced/Specialist Certifications
As part of the annual review process, the FOA enlists the assistance of dozens of experts to review our certifications and exams. That allows us to keep them up to date and even flag changes in our reference materials, The Fiber Optic Technicians Manual and Online Reference Guide.
We have just completed our review for 2009 and have made some changes that should interest our FOA members and schools.
FOA CFOTs with the proper experience can now more easily apply directly to the FOA and, if qualified, take the certification exam online locally with a designated proctor. Manufacturers' trainin, e.g. OTDR or fusion splicing training, will qualify as experience. Shorlty, you will be able to study using an online study guide. If interested, download a FOA Logbook and document your experience.
FOA schools should look at the CFOS certifications as the requirements for teaching classes has been clarified to include classroom and lab requirements. Now more courses will qualify for CFOS training, including, for example, OTDR training for CFOS/T or prepolished/splice connectors for CFOS/C. Check out the new CFOS page or contact the FOA for details.
New Sections on Splicing on FOA Online Fiber Optic Reference Guide
The FOA Online Fiber Optic Reference Guide keeps growing. This month, we added advanced sections on fusion splicing and mechanical splicing. Like the other sections, it's complete but written to be understandable, profusely illustrated and readable on your PC or iPhone or other web-enable device.
These sections are updated to support the revised FOA Specialist Certifications (CFOS). Now those interested in the FOA Specialist Certifications can study for their exams online. Watch for a CFOS study guide online.
The FOA Online Fiber Optic Reference Guide is now available for use. It's not complete - we expect it to never be "complete" but always expanding! We want you to contribute and give us feedback on how we can make it better!

Good Question! Tech Questions Worth Repeating
Followup: Old Cable (A recent call to the FOA asked if the problems they had with splicing and testing some premises singlemode cable might be due to its age.)
We Asked For Feedback From Manufacturers
We contacted some of my friends in the cable business and described the problem to them. Their reaction was similar to mine. If it was outdoor cable, there was probably no problem, but indoor cable could have been damaged by improper storage or by sitting on a reel for that long. Furthermore, one suggested that during the time that cable was manufactured, just after the telecom/dotcom market went “bust,” fiber optic the market was flooded by cheap, poor quality singlemode fiber and cable, some of it manufactured overseas.
Out of curiosity, I did some searching of the inventory of a couple of surplus cable dealers and found some cable just like the cable that was causing problems. 10,000 feet of it to be exact. But no mention of the age of the cable.
Certainly when times are tough, it’s tempting to find the cheapest suppliers. But just like we’ve been seeing counterfeit cables that may not meet spec or flammability codes, old cables from surplus may not be suitable for use any more. Unless the actual history of the reel of cable is known, using it is taking a big chance, since the total installation labor costs may be for naught. And, as is often the case, there is some question where the blame lies. It may end up in the courts and if that happens, we know everybody loses but the lawyers.
From April: Old Cable and Another OTDR Mess
Link Loss Budgets And OTDR Testing
We have always said that you need a link loss budget calculation for a cable plant in order to determine what are PASS/FAIL results when testing, but a reader asked us a question recently that clarified an important point.
Q: What happens when you test with an OTDR with its limited distance resolution? Specifically, if you have singlemode fiber terminated with fusion spliced pigtials, you cannot see the both splice and the connector losses. Or what if you have a patch panel with connections using short patchcords?
A: For insertion loss testing, you simply sum up all the loss contributors and get a total for the cable run. In the case of an OTDR, you are analyzing each event.
So if you have a connection point where both fibers were terminated with spliced-on pigtails, you should analyze the event as the sum of 2 fusion splices and one connection, not each individually. A patchcord termination would be two connection losses, plus splices if the termination was by splicing on pigtails.
But even if testing with an OTDR, remember an end-to-end insertion loss test is required too!
OTDRs vs Fusion Splicing Machine Readings
Q: When we fusion splice, the fiber machine shows splice losses of 0.00 to 0.04 dB, but tests with an otdr shows splice losses of 0.2 to 0.3 dB. Why?
A: There are several issues involved. The splicer uses a profile alignment system (http://www.thefoa.org/tech/ref/termination/fusion.html ) that estimates the losses based on software estimates of how well the fibers are aligned. It's just an estimate, as it cannot actually measure the loss, and issues like differences in the mode field diameters or backscatter coefficients of the two fibers can make a big - and directional - difference in the losses measured by an OTDR (http://www.thefoa.org/tech/ref/testing/OTDR/OTDR.html).
With the OTDR you should measure both ways with the OTDR and average. I suspect the larger losses could be directional issues with the OTDR and if you measure the other direction you will get lower losses.
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 To The Desk?
Maybe it's too late. While copper and fiber were fighting it our to connect up the desktop in LANs, wireless found more bandwidth and solved the security problems so users can have what they want: mobility. With the majority of new PCs being laptops or netbooks and Internet connections for cell phones and web-enable devices getting faster, wireless is the winner. However, the backbones and many wireless access points are fiber connected and fiber is the medium of choice in data centers.

Motorola Introduces LAN Based on FPON FTTH Network
Motorola’s Passive Optical LAN (POL) system derives from the vendor’s experience supplying gigabit passive optical network (GPON) equipment for Verizon’s fiber-to-the-premises network. Motorola’s POL is an all-fiber enterprise LAN connecting any stationary Ethernet-based device or system across the enterprise into the wide area network. It supports cabled and wireless connections and is certainly something anyone looking to upgrade a LAN should consider. (One would assume that supplying millions of pieces of hardware to Verizon means they have gotten the price low!)
