Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an optical fiber cable which can be easily taken out from inside without damaging an optical fiber.SOLUTION: An optical fiber cable includes: an optical fiber; a pair of tensile strength bodies 41a, 41b placed across the optical fiber; a pair of coating layers 12a, 12b for coating the pair of tensile strength bodies 41a, 41b; and a sheath 13 for coating the optical fiber and the pair of coating layers 12a, 12b overall. At a position between flat surfaces S1, S2 including apices 14a, 14b, 15a, 15b of the pair of coating layers 12a, 12b, the optical fiber is placed. Around the optical fiber, the sheath 13 is separated. The sheath 13 is not fused with or bonded to the pair of coating layers 12a, 12b from the apices 14a, 14b, 15a, 15b of the pair of coating layers 12a, 12b over to a side surface on the optical fiber side but is fused with or bonded on a remoter side from the optical fiber than the apices 14a, 14b, 15a, 15b of the pair of coating layers 12a, 12b.
【課題】光ファイバを損傷させることなく内部から容易に取り出すことができる光ファイバケーブルを提供する。【解決手段】光ファイバと、光ファイバを挟んで配置された一対の抗張力体41a,41bと、一対の抗張力体41a,41bを被覆する一対の被覆層12a,12bと、光ファイバ及び一対の被覆層12a,12bを一括被覆する外被13とを備え、一対の被覆層12a,12bの頂部14a,14b,15a,15b同士を含む平面S1,S2に挟まれる位置に光ファイバが配置され、光ファイバの周囲においては外被13が分断されており、外被13は、一対の被覆層12a,12bの頂部14a,14b,15a,15bから光ファイバ側の側面にわたって一対の被覆層12a,12bと融着又は接着されておらず、且つ一対の被覆層12a,12bの頂部14a,14b,15a,15bよりも光ファイバから遠い側において融着又は接着されている。【選択図】図1 |
