ABSTRACT:
An optical fiber composite ground wire includes a core having channels, loose tubes, each tube containing at least one ribbon optical fiber, and disposed in a respective channel, and external tensile wires surrounding the core. Since the optical fibers collected in the tube are the same in length, tension and breakage due to differences in length between the optical fibers can be prevented. Also, since ribbon optical fibers each having 2 to 8 cores are gathered in the loose tube, more than 12 cores can be assembled in the tube without special equipment. A UV-curable resin coating the outer surface of the ribbon optical fiber prevents water from permeating into the optical fibers and affecting optical characteristics.
