OPAC (optical power attached cable) is a type of fiber optic cable that is installed by attaching to a host conductor along overhead power lines. TBC extends from the cities of Pittsburg, CA to San Francisco, CA, and provides approximately 40% of the electrical power used on a. Electrical utilities have several cables available for their use on transmission towers and poles. Besides traditional cables lashed to messengers, figure-8 cables or ADSS cables, utilities can construct transmission links using optical ground wire (OPGW) or optical power phase conductor (OPPC). OPGW is made like a regular conductive wire, but in the center of the wire there is a hollow tube with some optical fibers inside. It is used as a shield for power conductors. The main function is to place the optical fiber in the ground wire of the overhead high-voltage transmission line to form the OPGW optical fiber communication network on the transmission line.
