Fiber optic surge protectors, also known as fiber optic lightning arresters, serve to shield fiber optic communication systems from lightning strikes and transient voltage surges. The optical fibers handle high-speed data transfer, while the copper conductors are used for power delivery. Its primary function is to suppress or divert surge currents, preventing them from damaging electronic equipment, communication.
