New Composite Fiber-Optic Overhead Ground Wire,
Abstract
A composite fiber-optic overhead ground wire (OPGW) has already been used commercially. Most of the electric power companies have the plans to establish new telecommunication networks by means of OPGW, and it is greatly needed to develop OPGW which has maximum number of fibers for specific ground wire size with low transmission loss, easy handling and higher reliability. We have developed 'New OPGW', which satisfies this demands. It has the following features: (1) 18 fibers within 75 sq mm ground wire. (2) The fiber is a pure silica core and a fluorine-doped cladding single mode fiber with the average transmission loss of 0.4 dB/km at 1.3 micron. (3) Six fibers are stranded into a compact bunch and three bunches are housed in the spiral grooves of an aluminum spacer. (Author)
