Abstract : A method and apparatus provides an essentially neutrally buoyant undersea electronic data communications link. A bundle of continuous synthetic fibers each having a diameter of about ten microns has individualized metallized layers coated to a thickness of about one to three microns and the whole lot is covered by dielectric insulation. The synthetic fibers, aromatic polyamide fibers or graphite fibers, are relatively light-weight yet have high tensile strengths to assure a sufficient load bearing capability for the undersea use and the number of thin metallized coatings without unduly weighting down the cable. The dielectric insulation layer is disposed coaxially outwardly of the coated fibers and optionally is provided with an outer sheath of conductive material for a return path. However in some applications a seawater return path is better. The size of the undersea link is variable to accomodate different frequency responses and the material of the metallized layers is variable to allow for different weighs and desired transmission characteristics. Optionally, the fibers can be interelated fields to aid in the transmisssion of signals.
