Optical fiber cable having a sheath and for setting in a conduit

摘要

An optical fiber cable which is suitably set in a conduit by pushing the optical fiber cable into the conduit so as to insert the optical fiber cable through the conduit and which does not reduce the ease of manufacture and the mechanical characteristics of the optical fiber cable. The optical fiber cable includes an optical fiber cable core wire and a sheath covering the optical fiber cable core wire, wherein a dynamic friction coefficient between a surface of the sheath of the optical fiber cable and a surface of a sheath of another optical fiber cable is 0.17 to 0.34, and a dynamic friction coefficient between the surface of the sheath of the optical fiber cable and a surface of a sheet composed of polyvinyl chloride is 0.30 to 0.40.

1. An optical fiber cable comprising:
an optical fiber core wire; and a sheath covering the optical fiber core wire such that the sheath surrounds the optical fiber core wire when the optical fiber cable is viewed in cross section, wherein a dynamic friction coefficient between a surface of the sheath of a first optical fiber cable and a surface of a sheath of a second optical fiber cable is 0.17 to 0.34, the sheaths of first optical fiber cable and the second optical fiber cable being of a same material composition, a dynamic friction coefficient between the surface of the sheath of the optical fiber cable and a surface of a sheet composed of polyvinyl chloride is 0.30 to 0.40, and a base resin of the sheath of the optical fiber cable is greater than 5% and less than or equal to 15% silicon resin by mass.
