    How to ground and protect communication optical cables from lightning

    There are two main lightning protection grounding solutions in fiber networks, namely intermediate grounding and terminal grounding. 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. Lightning poses several significant risks to fiber optic cables and the networks they support:. OPGW (Optical Fiber Composite Overhead Ground Wire) cables are designed with lightning protection in full consideration.
