[Claims for Utility Model Registration] (1) An optical fiber assembly in which a plurality of optical fibers 1 are assembled around the outer periphery of a tensile strength line 2, and a roughly wound tape 12 made of plastic is directly applied to the optical fiber assembly, In an optical cable having a structure covered with a sheath 4 via a cushion layer 3, the loosely wound plastic tape 12 has a shrinkage of 3% or less and 0.1% or more when heated at 100°C for 2 hours. An optical cable characterized by having a shrinkage amount. (2) Utility model registration claim 1, characterized in that the plastic constituting the loosely wound tape is selected from the plastic material group of polyethylene, polyester, polyimide, polyether sulfon, and polyether ether ketone. Optical cable described in section.
