OPTICAL FIBER CABLE

摘要

There is provided an optical fiber cable having a configuration in which a strand core of optical fibers is housed in a sheath and capable of fulfilling sufficient mechanical characteristics and ensuring a predetermined watertight property. The optical fiber cable includes a strand core 1 including a plurality of optical fiber strands 11 and watertight material strings 12, a tape body 2 covering the strand core 1, and a cylindrical sheath 5 covering the strand core 1 and the tape body 2, wherein the tape body 2 has water permeability, and the watertight material strings 12 are dissolved in water when the water permeates through the tape body 2, and the dissolved watertight material passes through the tape body 2 and flows into the sheath 5.
