Trunk cable

Fiber optic trunk cable is generally used for longer links, such as between floors or buildings. It should also be used in single-floor coupling link environments when many jumper cables and connections are required. If trunk cable is used, distribution panels must provide the hardware used to attach IBM® jumper cables.

A trunk cable typically contains from 12 to 144 fibers and has a strength member and an outer jacket. The physical trunk cable configuration varies and depends on user requirements, environmental conditions, and the type of installation required (for example, above ground or underground).
