Optical fiber duplex connector. An EIA/TIA 568SC- compliant
mated mechanical assembly designed to transfer power between two
pairs of fiber optic cable.
Patch cord. The fiber optic or stranded copper cable used to
connect the horizontal cabling and the backbone cabling to
Patch panel. A cross-connect system of mateable connectors that
Pathway. A facility for the placement and protection of
Pulling tension. The lateral force that may be applied to a
cable without adversely affecting the characteristics of the
Raceway. Any channel designed for holding wires or cables, e.g.,
conduit, EMT, sleeves, slots, underfloor duct, cellular floors,
surface mounted channels, in-furniture utility channels,
wireways, cable troughs, and busways.
Screen. A metallic foil or mesh that envelopes the pairs of a
cable. Screening is used to reduce the effects of EMI and RFI.
Service entrance. The point of entry into the building by
outside backbone cables through the exterior wall, concrete slab,
or from conduit.
Shield. A metallic foil or mesh around the insulation of a
conductor or pair of conductors. Shielding may also be applied
beneath the overall cable jacket to provide strength, physical
protection, and insulation from EMI and RFI.
Single-mode fiber optic cable. A fiber optic cable which is
designed to allow only one mode to propagate. Distances achieved
are a function of the quality of the light source.
Splice. The joining of conductors, generally from separate cable
Star topology. A configuration that provides connectivity
directly from the telecommunications outlet to the distribution
device. A star can be physically or logically constructed.
