Document Type and Number:

WIPO Patent Application WO/2018/101041

Kind Code:

A1

Abstract:

[Problem] To provide a novel optical cable from which an optical fiber can be easily withdrawn. [Solution] This optical cable is provided with: an optical fiber unit in which a plurality of optical fibers are surrounded by a press-winding tape; at least three tension members disposed, at intervals in the circumferential direction, on the outer side of the optical fiber unit; and an outer skin for covering the optical fiber unit and the tension members. The tension members are disposed in parallel to the optical fiber unit. The outer skin is formed between the optical fiber unit and the tension members. The inner wall surface of the outer skin formed between the optical fiber unit and the tension members protrudes further toward the center of the cable than the inner wall surface of the outer skin at which the tension members are not disposed. In the press-winding tape, a portion disposed on the inner wall surface, which protrudes toward the center of the cable, is recessed toward the center of the cable.
