OPGW (optical ground wire) is a conductive wire used in electrical transmission lines which is protects phase conductors against lightning strike. This conductor compounds grounding and communication functions.95mm². OPGW transmitter, have stainless steel tube which is have fiber optics, aluminum clads are wrapped with aluminum alloy wires.
The stainless steel tube is filled with thixotropic gel to protect fiber optics, which are inside of steel tube, from damages as mounting and running process.
