Service providers continue to build out high-bandwidth networks around the world. These networks use a great deal of fiber— all fiber in many cases—the medium that meets both their bandwidth and cost requirements. But just deploying the fiber is not enough; successful fiber network also requires a strong fiber cable management system. Management of the fiber cables has a direct impact on network reliability, performance, and cost. It also affects network maintenance and operations, as well as the ability to reconfigure and expand the network, restore service, and implement new services quickly. The proper fiber cable management system provides the bend radius protection, cable routing paths, cable accessibility and physical protection of the fiber network. If these elements are done right, the fiber network can deliver its full competitive advantages. Introduction Fiber is being deployed more aggressively because of competitive pressures, it's ability to profitably deliver new revenue generating services and its high bandwidth. A look at the numbers tells the bandwidth story with stark clarity. While twisted pair copper cable is still limited in its bandwidth capacity to around 6Mbps, and coaxial is limited to an STM-1 level of 155Mbps, single mode fibers are commonly being used at STM-1 (155Mbps), STM-4 (622Mbps), STM-16 (), and even higher levels around the world (see Table 1).
