Optical fiber cable OPGW (Optical Ground Wire) is a hybrid overhead cable that combines the role of a transmission line lightning protection conductor (ground wire) with built-in optical fibers for communications. Therefore, it is important to build a lightning protection. Building a lightning protection system for fiber optic cables is essential to safeguard the network infrastructure from potential damage caused by lightning strikes. Installed at the top of high-voltage transmission towers, OPGW replaces traditional. Although the signals in fiber cables are optical signals, most of the outdoor optical cables using reinforced cores or armored optical cables are easy to get damaged under lightning because of the metal protective layer inside the cable. What is OPGW (Optical Fiber Ground Wire)? OPGW is a.
