  • Lightning protection for fiber optic cable boxes

    Lightning protection for fiber optic cable boxes

    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. Their working principle involves rapidly discharging lightning currents, limiting overvoltage, and isolating metal connections to ensure equipment. This article explores the importance of lightning protection for fiber optic cables, the potential risks lightning poses, and the strategies used to safeguard these critical infrastructure components.
