Fiber Optic Cables Routing in Cable Management

By using a cross connect cabinet, cross-connect fiber cables are routed between two termination points while using standoffs, brackets, along with other wire management devices.

Cross connect wiring requires extra care in handling to maintain performance characteristics. Guidelines that are using in telephone-grade cross-connects are not whatsoever right for the larger performance types of LAN wiring. A good example: sharply bent jumpers really are a common practice when they’re wrapped around wire management brackets. But in fiber cable management, these sharp bends may be under the minimum bend radius recommended in TIA/EIA-568-B.

Various fiber cable routing schemes help achieve redundancy in SONET networks. Trunks are the main fiber cables that may carry hundreds of fiber strands of carries.

Laterals are the fiber cables in the customer premises towards the nearest splice point around the cable trunk. Within cities, laterals is often as short as a few meters or could extend several kilometers in suburban and rural areas.

Aerial installation on existing poles is the most cost-effective installation method while offering moderate reliability. Rules and operations for licensed carriers and fiber installers to access existing utility and telephone poles are very well established by regulatory bodies. Many regulatory bodies require carriers to install extra conduits which are accessible by other licensed carriers or fiber installers.

To be able to enhance the accessibility to cable telephony systems, some operators are installing redundant node receivers and transmitters, and connecting these to the headend using fiber optic cable having diverse routing.

Outdoor hardware consists of a type of fiber optic splice closures, wall-mounte distribution centers, and pedestal-mountable cross-connects. The unit provide environmental protection for splices, connectors, and jumpers within the outside plant environment, often required in industrial and other special applications.

In certain indoor circumstances, space is restricted for mounting hardware. Specially designed furcation (or fan-out) kits provide protection and pull-out strength for bare fibers, and they are direct connectorized. They are best when the fiber counts are low and all of the fibers is going to be patched into other hardware or electronics within the same are.
