Abstract
PURPOSE: To eliminate the disadvantage of poor space factor and poor economy at the time of providing a pair of power feed conductors separately from optical fiber cables by simultaneously providing a power feed function at the time of aggregating optical fiber cores.
CONSTITUTION: Twisting is applied to a conductive material 8 which serves a partition for optical fiber cores 1 and is radial in section. The cores 1 are inserted between the respective branches of this material 9 and an optical fiber core protecting insulation layer 10, a sheath conductor 6 and further a cable protecting sheath 7 are covered on the outside. Then, power feeding becomes possible through the material 9 and conductor 6 and by providing marks such as making the material 9 non-symmetrical, the identification of the cores at the time of connection is made easy. Putting a filler in the space 8 gives equally good results.
