FIBER OPTIC CABLE
An object of the present disclosure is to enable LPG applied over the entire length of an optical fiber without inhibiting an operation of taking out the optical fiber. The present disclosure relates to an optical fiber cable in which at least one or more optical fibers for transmission in at least two or more modes are gathered, the optical fiber cable including: a linear material abutting on at least one of the optical fibers, in which a thickness of the linear material periodically varies in a longitudinal direction of the linear material.
1 . An optical fiber cable in which at least one or more optical fibers for transmission in at least two or more modes are gathered, the optical fiber cable comprising:
a linear material abutting on at least one of the optical fibers,
wherein a thickness of the linear material periodically varies in a longitudinal direction of the linear material.
2 . The optical fiber cable according to claim 1 ,
wherein the linear material is formed of at least two linear materials twisted together and integrated.
3 . The optical fiber cable according to claim 2 ,
wherein tension is applied to at least one linear material of the at least two linear materials, and tension is applied to one linear material higher than tension is applied to any other linear material.
4 . The optical fiber cable according to claim 2 ,
wherein thicknesses of the at least two linear materials are constant in the longitudinal direction.
5 . The optical fiber cable according to claim 1 ,
wherein a position of the optical fiber varies randomly in the longitudinal direction of the optical fiber cable.
6 . The optical fiber cable according to claim 1 ,
wherein the linear material functions as a bundle tape which bundles at least one or more of the optical fibers.
7 . The optical fiber cable according to claim 1 , wherein the linear material has water absorbency.
