MIL-STD-2042-2B(SH)

3.27.1  FOCP spare fiber.  An unallocated spare fiber for use by any system using the FOCP.

3.27.2  System spare fiber.  A spare fiber that is allocated and not used and that is reserved for use by a specific system.

3.28  Trunk.  A set of trunk cables that run along the same cableways between two FOCP boxes (TRBs, FOICBs).

3.29  Trunk cable.  An optical fiber cable that runs between two FOICBs. Typically, trunk cables are run in the main cableways and have higher fiber counts per cable than local cables.

3.29.1  Conventional trunk cable.  A conventional optical fiber cable that runs between two FOICBs.

3.29.2  BOF trunk cable.  A single BOF cable connected between two FOCP TRBs or between a FOCP TRB and a FOCP FOICB.  A BOF trunk cable contains multiple BOF trunk tubes.

3.30  Tube furcation unit.  An assembly attached to the end of a BOF tube in a BOF cable used to separate the fibers and provide a cable structure to facilitate the termination of the optical fibers from that BOF tube.

3.31  Unused fiber. A fiber that is not designated for use for any system and not required as part of the FOCT configuration.  Unused fibers occur within the

fiber optic cable topology when the required systems fibers are less than the number of fibers available within a standard cable size.
