MIL-STD-2042B(SH)
3. DEFINITIONS
3.1 Acronyms. The acronyms used in this standard practice are defined as follows:
a. BOF - Blown Optical Fiber
b. FOCP - Fiber Optic Cable Plant
c. FOCT - Fiber Optic Cable Topology
d. FOICB - Fiber Optic Interconnection Box
e. TRB - Tube Routing Box
3.2 BOF cable. A cable that contains one or more BOF tubes through which optical fibers or optical fiber bundles are blown.
3.3 BOF cable furcation. An assembly that joins the multiple tubes in a multi-tube BOF cable to multiple single tube BOF cables.
3.4 BOF cable splice. A joint of two BOF cable ends in which the tube ends are connected together using tube couplers and the joint environmentally sealed using a shrink sleeve.
3.3 BOF fiber. An optical fiber with a special coating that allows the fiber to be blown into a BOF tube.
3.4 BOF bundle. A group of optical fibers within a special jacket that allows the entire bundle to be blown into a BOF tube.
3.5 End user equipment. End user equipment refers to any cabinet, case,
panel, or device, that contains components that are either the origin or destination
of an optical signal.
3.6 Fiber optic cable plant (FOCP). A subset of the FOCT that excludes local cables and their associated components. A conventional FOCP includes FOICBs, trunk cables and their associated connectors and splices. A BOF FOCP consists of FOICBs, TRBs, tube couplers, BOF trunk cables, BOF fibers, BOF bundles, tube furcation units, and associated connectors and splices.
3.7 Fiber optic cable topology (FOCT). An integrated optical fiber distribution system that provides the optical interconnection between end user equipments. A conventional FOCT includes the conventional FOCP components and outlet boxes, local cables and their associated connectors and splices. A BOF FOCT includes the BOF FOCP components, BOF cable furcations, local cables, local BOF cables, outlet boxes, and associated connectors and splices.
3.8 Local cable.
3.8.1 Local conventional cable. A conventional optical fiber cable that runs between end user equipment and an FOICB (or outlet box), or between an FOICB and an outlet box.
3.8.2 Local BOF cable. A BOF cable that runs between end user equipment and a
TRB, or between a TRB and an outlet box.
3.9 Outlet box. An outlet box is a small termination box used to break out a local cable from an interconnection box to one or more equipments within a compartment.
3.10 Trunk cable. An optical fiber cable that runs between two fiber optic interconnection boxes. Typically, trunk cables are run in the main cableways and have higher fiber counts per cable than local cables.
