Abstract
An optical fiber cable comprises a plurality of optical fibers, tensile strength fibers that accommodate the plurality of optical fibers, and a sheath formed with a thermoplastic resin and covering the tensile strength resin. In this optical fiber cable, when a Young's modulus of the sheath at 0° C. is E [MPa], a cross-sectional area of the optical fiber cable is S [mm] and an inner diameter of the sheath of the optical fiber cable is Di [mm], ES (0° C.) [N] which is the product of the Young's modulus E at 0° C. and the cross-sectional area S, and the inner diameter Di [mm] satisfy:
