Title:
光ファイバケーブル
Document Type and Number:
Japanese Patent JP5638745
Kind Code:
B2
Abstract:
An object of the present invention is to provide 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 (1) and a sheath (3) covering the optical fiber cable core wire (1), wherein a dynamic friction coefficient between a surface of the sheath (3) of the optical fiber cable (20) and a surface of a sheath (3) of another optical fiber cable is 0.17 to 0.34, and a dynamic friction coefficient between the surface of the sheath (3) of the optical fiber cable (20) and a surface of a sheet (35) composed of polyvinyl chloride (PVC) is 0.30 to 0.40.
