OPNW, which takes charge of the outer neutral wire role and the inner optical network role, was developed at the first time among nation and substituted the neutral wire of distribution line between electric power substation and neighboring station. This paper refers to results about its optical character measured periodically, and examines closely whether the unique matter will be occurred or not about the role of neutral wire during more than one year. Also, established OPNW became a new chance to distribution facility's working by establishing remote portrait supervisory system and doing remote supervisory about essential equipment of distribution line.

The thesis here by shows that the extant suspension wire, which is stretched between electric poles to support a variety of communication wires, can be replaced by specially-redesigned cables called OPSW(Composite Suspension Wire with Optical Fiber) which have been devised for the first time in the world so that the functions of both communication and support can be united into one cable which is sure to be successfully installed on site, hence leading to outstanding effects that it can sharply reduce the load applied to electric poles as well as the cost of forthcoming constructions and that it can accordingly make a great contribution to the building of Smart Grid network.
