Abstract

PURPOSE: To well protect the optical fibers of a cable and increase the density of the cable by twisting a plurality of optical fibers having a buffer layer around a wire central body and forming the cable with a foamed layer covering the twisted fibers and a metal tube compressing the layer.
CONSTITUTION: A plurality of optical fibers 1 having outer buffer layer 3 are twisted together around central body 5 of filament such as steel wire. Plastic foam layer 6 of polyethylene foam or the like is formed on the outside of the twisted structure, and metal layer 7 of copper or other metal is formed on the outside of layer 6. At this time, layer 6 is compressed by layer 7. By this construction layers 6, 7 give mechanical strength and well protect fibers 1 with respect to the transmissive characteristics. In addition, the internal structure is solid and stable, resulting in increased density.
