Abstract
There is provided an optical fiber composite ground wire (OPGW). The optical fiber composite ground wire (OPGW) includes a central wire at the center of the optical fiber composite ground wire (OPGW), a steel tube disposed around the central wire, at least one optical fiber ribbon inserted into the steel tube and containing a plurality of optical fibers arranged in coplanar alignment, a filling material filled in the steel tube, at least one inner layer wire surrounding the central wire, and at least one outer layer wire surrounding the steel tube and the inner layer wire.
