Abstract:
A jacket is provided to the outer circumference of a cable core, a rip cord, and a tension member. The cable core, the rip cord, and the tension member are collectively covered by the jacket. A wrapping tape is longitudinally placed on the outer circumference of a core part so as to be wound therearound. Thus, immediately after the wrapping tape is longitudinally placed and wound, a wrap part thereof is formed so as to lie substantially straight in the axial direction of an optical fiber cable. In contrast, in an optical fiber cable, the cable core is obtained by combining and intertwining the core part and the wrapping tape. Because of this configuration, the wrap part of the wrapping tape is helically disposed in the longitudinal direction.
