While nonarmored fiber optic cables don't require grounding due to their nonconductive properties, grounding is crucial when using armored fiber optic cables. Therefore, it is important to build a lightning protection system for fiber optic cables. How to Protect Fiber Optic Cable From Lightning? The major purpose of lightning protection systems is to conduct the high current lightning discharges safely into the Earth/ground. There are two main lightning. Fiber optic cable transmits data as light through glass or plastic strands, which means the fiber core itself carries no electrical current and requires no grounding. However, this does not mean every fiber optic installation is exempt from grounding requirements. Lightning-induced surges can travel through power lines, telecommunication lines, or nearby metallic structures and pose a. There are two main lightning protection grounding solutions in fiber networks, namely intermediate grounding and terminal grounding. These solutions use two ways of grounding for optical cable links both in domestic and foreign standards. However, because fiber optic cable has strengthened core, especially the direct-buried fiber optic cable has armoring layer.
