The OPGW optical cable is also called the optical fiber composite overhead ground wire. It is a special optical cable combined with the optical fiber communication unit and the overhead ground wire (lightning conductor) of the power transmission line in recent years. It has the dual functions of ground wire and communication and is widely applied to the domestic high-voltage and super-high-voltage transmission line.
