  • Should fiber optic terminal boxes be grounded

    Should fiber optic terminal boxes be grounded

    Although most fiber optic cables are not conductive, any metallic hardware used in fiber optic cabling systems (such as wall-mounted termination boxes, racks, and patch panels) must be grounded. Conductive cables require proper grounding and bonding for applicable conductors. This AE Note does not address outside plant fiber optic installations or. Since an optical fiber cable is non-conductive and there is no electric flowing, there are several advantages over a twisted copper cable in deploying: The non-conductive (dielectric) characteristics of fiber impacts how a designer lays out cabling pathways. Their function is mechanical stabilization, environmental isolation, and controlled fiber management. Installation errors do not typically cause immediate link failure. These cables include metallic components that can carry electrical currents, presenting potential hazards such as electrical shock or fire. “What needs to be grounded in a fiber optic network?” The standard answer of “everything” seemed illogical and was unsatisfactory to him.
