  • Does directly buried optical fiber cable require lightning protection

    Does directly buried optical fiber cable require lightning protection

    Direct burial fiber cables are laid with lightning protection wires according to the soil resistivity, and the aerial fiber cables are grounded with grounding poles and suspension wires. There are two main lightning. However, because the optical cable has a reinforced core, it is particularly The directly buried optical cable has an armor layer, so when the optical cable line is struck by lightning, the optical cable can also be burned or damaged. UV Exposure: Prolonged sunlight degrades standard plastic jackets, making them brittle. Temperature Extremes: Expansion and contraction can cause stress fractures. Corning Optical Communications' cables ar avai � (depth to which the ground freezes annually).
