Abstract
A cable which includes conductor bundles prepared from at least one optical fiber positioned either centrally or helically about the center axis of the bundle, metallic conductors helically positioned around the bundles center axis, and a polymeric insulation material. A method of making a cable including forming a conductor bundle by placing helically positioned conductors and optical fibers about the periphery of a central optical fiber or metallic conductor, encasing the conductors, optical fibers, in a polymeric insulation material, and grouping the conductor bundles together.
