Abstract

PURPOSE: To provide power feed function to an optical fiber cable without impairing the characteristics that the optical fiber cable possesses by imparting conductivity to the optical fiber core.
CONSTITUTION: A primary covering 2 and cushion layer 3 are provided to an optical fiber bare wire 1. A secondary covering 4 composed of plastics imparted with conductivity is provided thereon. The covering has conductivity and has the characteristics of protecting the bare wire 1 from external force together with the layer 3. An insulation layer 7 is covered on such optical fiber core wire and even if a plurality of these are aggregated in close contact within the cable, there is no leakage of power and the aggregation of high density is made possible.
