Abstract
An optical fiber composite overhead ground wire in which a plurality of optical fibers are wound together on a tension member to form an optical unit. A plurality of such optical units are disposed in a spacer around which ground wires are wound. The optical fibers within a unit are identified by color and possibly winding order. Each tension member is also identified from other tension members so each optical fiber can be uniquely identified.
