光纤复合架空地线（OPGW）光缆通信是将光纤单元复合于送电线路地线内，利用光纤单元开通通信通道兼具地线和光缆的双重功能。它随高压输电线路一起架设，不需占用新的敷设走廊，是一种传输容量大、可靠性高、不受强电干扰的通信方式。湖北“220KV天堂抽水蓄能电站－路口变送电
Optical fiber composite overhead ground wire (OPGW) Optical fiber communication is the optical fiber unit compound in the power transmission line ground, the use of optical fiber unit opened communication channel both ground and optical cable dual function. It is erected along with high-voltage transmission lines and does not occupy the new corridor. It is a communication method with large transmission capacity, high reliability and no strong electric interference.
