Aerial optical cable lines are susceptible to lightning damage
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. If an optical cable contains metal elements in its design, then they are exposed to current, the value of which can reach several tens of ki-loamperes. It is the magnitude of the current during lightning strikes and the consequences of its impact on objects that have always attracted the at-tention. 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.
