Abstract

A composite cable for distributing electrical power to components in an optical fiber network and for transmitting optical signals between optical fiber network components includes at least one layer of insulated electrical conductors arranged in side-by-side relation to provide a layer of conductors of a thickness substantially equal to the thickness of the conductors. The conductors of the at least one layer of conductors are S-Z stranded and surround the optical fibers which are loosely contained in at least one plastic buffer tube to provide desirable structural and operational features to the cable and to an optical fiber network in which the cable can be included.
