The optical fiber is laid on the ground wire of the overhead high-voltage transmission line, and the optical fiber communication network is formed on the transmission line. This structure has the dual function of ground wire and communication, and is generally called OPGW fiber optic cable.
Optical fibers are resistant to electromagnetic interference and light weight, and can be installed on top of transmission line towers without considering the optimal installation location and electromagnetic corrosion. So, OPGW has the characteristics of high reliability, superior mechanical properties, and low cost. This technology is particularly useful and economical when laying or replacing existing ground wires.

Photoelectric composite cable (OPLC) is to place the protected optical fiber unit in the power cable, which can be used in power systems with rated voltage of 0.6/1KV and below. It integrates optical fiber, transmission copper wire, and copper signal wire. Broadband access, equipment power consumption, emergency signal transmission and other issues.
In addition, it can also be customized according to customer needs. Due to the diversity of access methods and the complexity of the use environment, manufacturers can also customize according to customer requirements, according to different voltages, different fiber cores, and different structures to ensure the safety and reliability of the network.
