Can fiber optic distribution boxes attract lightning
Fiber optic cables have good protection performance, and the metal components of cable's insulation value is so high that lightning current can not enter the cable easily. However, because fiber optic cable has strengthened core, especially the direct-buried fiber optic cable has armoring layer. Building a lightning protection system for fiber optic cables is essential to safeguard the network infrastructure from potential damage caused by lightning strikes. Lightning-induced surges can travel through power lines, telecommunication lines, or nearby metallic structures and pose a. Since glass is non-conductive, does that mean fiber optic systems are naturally immune to lightning damage? Actually, the assumption that fiber optic systems are naturally immune to lightning damage because glass is non-conductive is only partially correct. While it is true that the optical fiber. 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. Therefore, it is important to build a lightning protection.
