ABSTRACT:
This specialized fiber optic jumper cable includes a composite cable with a glass fiber light guide for single or multi transmission mode, standard fiber optic connectors, electrically powered light emitting devices at the fiber optic connectors, and a pair of electrical conductors embedded in the cable, with one or more electrical power connectors for selectively applying an external electrical power source to the light emitting devices. One embodiment has a fiber optic connector at each end of the jumper. An LED and an electric power connector suitable for plug-in connection of a power pack are affixed to the cable adjacent each end such that both LEDs are lighted whenever power is applied to either of the electrical connectors. The attendant illumination of the LEDs provides an indication that the tracer system is activated and functioning properly and readily indicates where both ends of the same jumper cable are located. The electrical conductors also may be used for convenient telephonic communication by service personnel. A further pair of electrical conductors may be provided in the cable for auxiliary uses, if desired.
