Lower operations costs, greater reliability and flexibility in service offerings, quicker deployment of new and upgraded services—these are the characteristics of a successful service provider in a competitive global market. Service providers continue to build out high-bandwidth networks around the world. These networks use a great deal of fiber—the medium that meets both their bandwidth and cost requirements. But just deploying the fiber is not enough; a successful fiber network also requires a well built infrastructure based on a strong fiber cable management system.

Service providers continue to build out high-bandwidth networks around the world. These networks use a great deal of fiber the medium that meets both their bandwidth and cost requirements. But just deploying the fiber is not enough a successful fiber network also requires a well built infrastructure based on 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. A strong fiber cable management system provides bend radius protection cable routing paths cable accessibility and physical protection of the fiber network. If these concepts are executed correctly the network can deliver its full competitive advantages. Introduction Facing ever-increasing competition service providers deploy fiber because of its high bandwidth and its ability to deliver new revenue-generating services profitably. A look at the numbers clearly tells the bandwidth story. While twisted pair copper cable is limited in its bandwidth capacity to around 6Mbps and coaxial cable is limited to an STM-1 level of 155Mbps singlemode fibers are commonly used at STM-1 155Mbps STM-4 622Mbps STM-16 and even higher levels around the world see Table 1 .
