Abstract

PURPOSE:To enhance the tensile strength of an optical cable, by arranging an optical fiber and solid wires, pairs, or quads of copper cable conductors around a center tension member while bringing them into contact with the center tension member. CONSTITUTION:13 Pairs of 0.9mm. copper cable conductors are arranged around a center tension member 10 consisting of, for example, 1.4mm.X7 steel stranded wires, and 15 pairs of 0.9mm. copper cable conductors are arranged in the next layer after providing a fixing winding 42, and a fixing winding 40 is provided. Thus, the tensile strength is enhanced.
