  • Does optical fiber cable belong to electrical engineering

    Does optical fiber cable belong to electrical engineering

    770 of the National Electrical Code (NEC) provides the general requirements for optical fiber cables. Utilities build fiber optic networks in similar ways that others build them, aerial and underground, but they also mix aerial cables in their power distribution cables, sharing towers and poles. These cables are used mainly for digital audio connections between devices. A fiber-optic cable, also known as an optical-fiber cable, is an assembly similar to an electrical cable but containing one or more optical fibers that are used to carry. A TOSLINK optical fiber cable with a clear jacket. In this application the fiber cable is classified as a fiber supply cable, and can only be installed, maintained and handled by electric. bles in a high voltage environment, with typical line voltages of 115 kV or more, requires the evaluation of certain critical parameters.
