Lightning protection is one of the key reasons for utilizing fiber optics. Unlike copper wire, the fiber itself is made from dielectric (non conducting) materials, cannot conduct electrical current, and is immune to EM radiation. Telecommunication equipment and communication lines located at or near power generating facilities, sub stations, high voltage transmission towers, PCS/Wireless and E911 antenna sites, are exposed to potential damage and destruction by lightning strikes, power surges and Ground Potential Rise (GPR) events. This is an important consideration, because not only is the equipment and related services at risk, but personnel working in these environments are also at risk of serious injury or death should a GPR event or lighting strike occur. Industrial network components must be capable of withstanding harsh environmental conditions such as extreme temperature ranges as well as lightning strikes, Ground Potential Rise (GPR) events and power surges.
