Abstract
Abstract A flat communication cable is formed of an assembly of standardized modules in edge-to-edge relation surrounded by an overlying polyester protective cover. The modules containing a PVC jacket are united to form a ribbon by a blend of fusion and hot melt adhesive material, and the protective cover is bonded thereto by the adhesive. The modules can contain polyolefin insulated wire pairs, coaxial electrical conductors, stranded or solid wire, fiber optic filaments, or the like. Semiconductive or non-conductive material can be incorporated in the PVC jacket of the modules and/or the adhesive as desired and in any combination. Drain wires can be included. Also, the cover material can include metallic layers for shielding.
