Abstract
PURPOSE: To enable faults to be limited to one segment of a cable in the cable inside or cable connection part, by providing a plurality of the waterproof dam parts filled with synthetic resin in a copper pipe in the longitudinal direction of the cable.
CONSTITUTION: The cable is formed into the construction consisting in making the circumference of the optical fiber cores 2 airtight with the airtight part 8 of epoxy resin between the cable cores 7; therefore, even if one of the cable core 7 ruptures and causes water running in the copper pipe 4, the water running is perfectly stopped by the airtight part 8 of the epoxy resin. Namely, the effect of water running is limited to one segment, and this makes it possible to prevent such troubles as increased light losses in the entire segment and the occurrence of trouble in the entire part of the communication system necessitating the on account of direct exertion of sea water pressure upon the optical fiber core. repair of the entire cable.
