Abstract

PROBLEM TO BE SOLVED: To improve a cable passing property when inserting an optical fiber unit which requires print into the pipe of a pipe composite cable for future laying. SOLUTION: A resin sheath 13 to cover the outer periphery of a coated optical fiber 12 has a bilayer structure consisting of an inner layer 14 and an outer layer 15, and printing 16 is applied to the circumferential surface of the inner layer 14, and the outer layer is formed by a transparent resin to compose the optical fiber unit 11. The optical fiber unit 11 is inserted into the pipe of the pipe composite cable for future laying in which a DV line (insulated wire) is integrated with the pipe for inserting the optical fiber unit. The insertion of the optical fiber unit 11 into the pipe does not cause the problem that friction becomes large under the effect of a printing ink layer 16, and the cable passing property is satisfactorily maintained. There is also no risk of causing print peeling.
