Fiber to the desktop, Wi-Fi networks and copper prices affectplans. "The enterprise network is undergoing a major shift inemphasis that impacts cabling," according to Jim Hayes of the FiberOptic Association, the international non-profit professionalsociety for the fiber-optic industry that develops educationalprograms and certifies fiber-optic technicians.
"Users expect mobility, demonstrated by the sales of laptopsexceeding desktop computers and the popularity of mobile platforms like the BlackBerry and iPhone. Wireless has had growingpains, but with the advent of 802.11n, better cell phone data systems and the likelihood of success for WiMAX, users now haveadequate wireless bandwidth practically everywhere and are notcrazy about being tethered to a patch cord.
"The network of the future is certainly not recabling every coupleof years with another UTP upgrade," he adds. "If 10-GigabitEthernet needs to be delivered to the desk, it's probably going tobe on fiber, not just for the bandwidth, but also for the lower power consumption. But I'm betting on more mobile applications, with abackbone of fiber connecting wireless access points. That's howcell phone networks are built, as well as many metro Wi-Finetworks."
With most large enterprises already depending on fiber backbones,adding adequate wireless access is easy, and, of course, upgradesare simply a matter of replacing wireless access-point hardware.
Zone cabling with fiber to the zone hub is the first step to fiberto the desktop (FTTD). Fiber has been a crucial part of the campusand riser solution for years; now, fiber is reaching the horizontalplane in the structure with a host of economic and functionalbenefits.
Currently, plenum-approved communications cable dominates new building installs in the United States.Return-air plenum design is still less expensive than ductingfeed-and-return HVAC. That brings up another area of concern:supply.
Copper continues to be a cost concern, as well as a supply issue.The most significant supply weak point, however, is thefluoropolymer materials used to insulate high-performancecopper-based twisted-pair cabling for plenum-approved cable.
There are only two major producers of the fluorinated ethylenepropylene (FEP; commonly known by their trade names: Teflon fromDuPont and Neoflon by Daikin USA). If either or both of thesematerial suppliers have a problem, the entire communicationsindustry may have a problem. The National Electrical Code (NEC) maybe changed to allow other cable constructions to be approved, butthat process with the National Fire Protection Association (NFPA)takes three years.
