Abstract

PURPOSE: To reduce the number of the optical fiber communication systems to be fed by one feed system, protect the cable from external force and obtain the cable of high reliability by dividing the feed systems to a plurality through provision of a plurality of the feeders.
CONSTITUTION: The cable comprises providing a plurality of internally aggregated optical fibers 3 in the 1st metal shell 9, providing a feeder support 10 having a plurality of grooves along the lengthwise direction on the outside circumference thereof, housing plural power transmission feeders 11 in a plurality of the grooves 12 of this support 10, providing a steel stranded-wire layer 4 on the outside circumference of the feeder support 10 housed with the feeders 11, further disposing the 2nd metal shell 6 for hermetic closing on the outside thereof and covering the outside of the 2nd metal shell 6 with protectors, such as plastics. As a result of this, even if the cable is exerted with mechanical forces such as crushing force, water pressure and tension from the outside, the optical fibers are protected from these forces and the submarine optical cable of high reliability may be obtained.
