An indoor cable 1 configured from an optical fiber core 3, tension members 7, an outer sheath 11, and the like. The outer sheath 11 integrates the optical fiber core 3 and the tension members 7 with one another. The outer sheath 11 is configured from a transparent material. The optical fiber core 3 comprises a glass wire and a resin coating (primary resin layer and secondary resin layer). Inherently, this optical fiber core 3 does not have a colored layer formed around the outer circumference of the resin coating layer; hence, in other words, the optical fiber core 3 is configured overall from transparent materials. A pair of tension members 7 are provided on both sides of the optical fiber core 3 at a distance from the optical fiber core 3. The tension members 7 are configured from a transparent material. |
