摘要： 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).

摘要： One or more optical fiber elements each constituted by a coated glass fiber are fed to an over-coating device and an over-coating is applied to the optical fiber elements in a lump, the feeding speed of the optical fiber elements to the over-coating device is made larger than the take-up speed of the over-coated optical fiber onto a take-up reel so as to give longitudinal compression strain to the glass fibers of the over-coated optical fiber. The glass fiber has compression strain of not less than 0.03% to less than 0.10% in a longitudinal direction thereof at room temperature.
摘要翻译：将一个或多个由涂覆的玻璃纤维构成的光纤元件供给到过涂层装置，并且一次性地将光纤元件的覆盖层施加到光纤元件上，将光纤元件的进给速度提供给覆盖层使装置比覆盖光纤的卷绕速度大到卷绕卷轴上，从而对被覆光纤的玻璃纤维施加纵向的压缩应变。玻璃纤维在室温下的纵向的压缩应变为0.03％以上且小于0.10％。
