The Bit to See at CeBIT
To be fair, Agilent's new product is pretty nifty, because it gives a new meaning to the term "modular tester." Also, it could save carriers a ton of money, according to Agilent, and that's what really counts these days.
So, let's start with the modular moniker. Pretty much all the manufacturers of gear for testing optical stuff in the field claim to have modular solutions. Usually, that means they've got a chassis into which various modules can be slotted, such as an OTDR (optical time domain reflectometer), an optical spectrum analyzer, and dispersion measurement modules. If engineers don't need some of the modules, they can lighten their load by leaving them out. However, they still have to lug around the chassis.
Enter Agilent. Its tester is somewhat similar to the stackable networking gear sold to enterprise users. Its modules simply clip on to a standard front end, so there's no chassis with empty slots to cart around.
Agilent says the other big thing about its tester is that it's been designed to help field staff work more efficiently. Agilent's R&D folk spent a lot of time with carrier engineers, studying how they work and identifying common causes of inefficiency, and then built a tester to help them do their jobs faster.
Frank A. Maier, operations manager for Agilent's optical network test business unit, offers an example. Nowadays, cables often have 864 fibers in them, and, after installation, each fiber needs to have at least two wavelengths tested in two directions. That's a heck of a lot of testing, and the chore typically takes 72 hours. Agilent's gear cuts this to 9.6 hours, according to Maier.
Agilent claims similar improvements in efficiency in dealing with maintenance problems, pointing out that even a small improvement in efficiency equates to huge savings for carriers.
On a typical day, says Maier, Verizon Communications Inc. (NYSE: VZ) receives 1 million phone calls reporting faults. About 95 percent are dealt with on the phone, but the remaining 5 percent -- 50,000 fault reports -- have to be dealt with by sending an engineer to investigate. To make matters worse, 22 percent of visits end up failing to rectify the fault, so an engineer has to make a return visit.
The bottom line, according to Maier, is that Verizon spends half its operating budget on fixing faults. Now, here's the amazing bit: Its operating budget totals a staggering $25 billion a year. By that reckoning, improving fault fixing efficiency by just one percent would save $125 million a year.
Agilent's new modular network tester, by the way, costs in the order of $24,000 for a typical setup.
