摘要： PROBLEM TO BE SOLVED: To provide an optical fiber cable having excellent branching workability, and a method for branching the optical fiber cable.SOLUTION: An optical fiber cable 1 comprises a sheath 3, inclusions 5, coated optical fibers 7, tension members 9, protective barriers 13, a supporting wire 15, and the like. The inclusions 5 require a certain level of rigidity to surely transmit force to the whole of the coated optical fibers 7 from both sides via the inclusions 5 during manufacturing. For example, if the inclusions 5 are easily deformed to be squashed by pushing pressure of the sheath 3, they become cushion layers, and force applied from both sides of the coated optical fibers 7 decreases. Thus, irregularities may be caused in the alignment of the coated optical fibers 7. Therefore, repulsive force is preferably 48 N/100 mm or more when 90% of an outer diameter is changed with respect to compressive force in a direction vertical to longer directions of the inclusions 5.
摘要翻译：要解决的问题：提供一种具有优异的分支可加工性的光缆和一种分支光缆的方法。解决方案：光缆1包括护套3，夹杂物5，涂覆光纤7，张力构件9，保护屏障13，支撑线15等。夹杂物5需要一定程度的刚性，以在制造期间通过夹杂物5从两侧确实地将力传递到整个涂覆的光纤7。例如，如果通过推压护套3的压力使夹杂物5容易变形而被压扁，则它们成为缓冲层，并且从涂覆的光纤7的两侧施加的力减小。因此，在涂布光纤7的排列方面可能引起凹凸。因此，当垂直于较长方向的方向相对于压缩力改变90％的外径时，排斥力优选为48N / 100mm以上的夹杂物5。

Thus, irregularities may be caused in the alignment (array) of the coated optical fibers 7. Therefore, the inclusions 5 are formed by twisting a predetermined amount of yarn. The twisting amount of the yarn is preferably 10 times or more and 30 times or less per 1 m.
