Abstract
An indoor cable is composed of an optical fiber core, tension members, an outer sheath, and so forth. The optical fiber core and the tension members are integrated by the outer sheath. The outer sheath is composed of a transparent material. The optical fiber core includes a glass wire and a resin coating (a primary resin layer and a secondary resin layer). The optical fiber core does not have a colored layer that is conventionally formed on the outer periphery of the resin coating layer. That is, the optical fiber core is composed entirely of transparent materials. On both sides of the optical fiber core, separate from the optical fiber core, is arranged a pair of tension members. The tension members are composed of transparent materials.
