摘要： PROBLEM TO BE SOLVED: To provide an optical cable for which a fiber density is improved, a diameter is reduced and post-branching at an intermediate position is easily performed.
SOLUTION: Since optical units 14 are integrated by twisting without providing a sheath for each tape laminated body 12 and the optical cables 10 and 30 are constituted by stranding a plurality of the optical units 14, the diameter of the optical cables 10 and 30 is reduced. Also, since the optical cables 10 and 30 can be constituted of the tapes 11 of the relatively low number of fibers, post-branching work at the intermediate position of the optical cables 10 and 30 is facilitated. Also, since the twisting direction of the tape laminated bodies 12 and the stranding direction of the optical units 14 are opposite, the difference of the lengths of the tracks of a tapered coated optical fiber 11 on the inner side and the tapered coated optical fiber 11 on the outer side is offset, the tension and remainder of the tapered coated optical fiber 11 are prevented and loss increase is prevented.

摘要翻译：要解决的问题：为了提供纤维密度提高的光缆，直径减小，并且易于在中间位置进行后分支。解决方案：由于光学单元14通过扭转而集成，而不需要为每个胶带层叠体12提供护套，并且光缆10和30由绞合多个光学单元14构成，光缆10的直径和 30减少。此外，由于光缆10和30可以由相对较少数量的光纤的带11构成，因此便于在光缆10和30的中间位置的分支后工作。此外，由于带状层叠体12的扭转方向和光学单元14的绞合方向相反，所以内侧的锥形涂覆光纤11的轨迹长度与锥形涂覆光纤11的距离差在外侧偏移，防止锥形涂覆光纤11的张力和余数，并且防止损失增加。版权所有（C）2004，JPO
