Abstract
An optical fibre submarine cable is made by extruding a metallic pressure tube by a friction extrusion technique, compressing the tube, applying tensile strength members, applying a conductive tape over the strength members and extruding plastic dielectric material over the tape. Armoring can subsequently be applied for shallow water application.
