Abstract
An optical fiber cable having excellent workability and long-term reliability. The cable comprises at least one optical fiber, a plastic jacket covering the optical fiber or optical fibers, and at least one anti-shrink member embedded in the jacket. The jacket has a longitudinal shrinkage of at most 0.5% when heated at 110° C. for two hours. The cable has a remaining bend with a radius of curvature of at least 100 mm when wound on a 50-mm-radious mandrel and heated at 85° C. for two hours. The deflection of a 30-cm-long cantilever made of the cable is at least 50 mm. In one aspect of the cable, the cable is specified by the conditions of ESt/ESj≧0.7, EIt/EIc≧0.1, and EIc/Mc≦8×106 mm3 (E: Young's modulus; S: cross-sectional area; t: total of anti-shrink members; j: jacket; I: geometrical moment of inertia; c: cable; and M: mass).
