ABSTRACT:
The flame-retardant cable of this invention is a single-core or multiple-core cable comprising a plastic optical fiber and at least one covering material covering this plastic optical fiber, and this flame-retardant cable is characterized in that at least one covering material is a highly flame-retardant resin, for example, a highly flame-retardant resin having an oxygen index (OI) of at least 32, preferably from 40 to 45, such as chlorinated polyethylene. This flame-retardant cable has an excellent flame retardancy with no lowering of the performances of the optical fiber. Moreover, the cable has an excellent flame resistance.
