A Distributed NetworkA Distributed NetworkCopper and FiberCopper and Fiber
In a conventional distributed structured cabling design, backbone cable is optical fiber, where thehorizontal segment of the network typically consists of twisted-pair copper cable or optical fiber cable (depending on distance). Backbone cables in an inter-building network travel from a main cross-connect (distributor) to one or more horizontal cross-connects within the telecommunication rooms on each floor, which includes active electronics equipment such as hubs, concentrators or switches.
FiberOpticsLANSection
Optical fiber’s bandwidth and ability to carry data over long distances is best utilized in centralized networks. Centralized networks have more unblocked bandwidth than distributed networks and therefore better suited for combined voice, video and data traffic requiring quality of service implementation. Optical fiber eliminates intermediate closets, thus simplifying network layout and reducing overall system cost. A centralized network is the most efficient and cost-effective way to implement a fiber-centric LAN.

Zone Cabling ArchitectureZone Cabling Architecture
Moves, adds or changes in an open-office environment can be accommodated quickly and efficiently through consolidation points by combining permanent feeder cabling with pre-terminated plug-and-play extender cables associated with the work area. Providing connectivity closer to end-users not only adds flexibility, but also reduces network downtime and re-cabling ends, which can result in significant cost savings.
