  • Why do optical cables need protective grounding

    Why do optical cables need protective grounding

    Many fiber optic cables include metallic components — such as steel armoring, aluminum moisture barriers, copper strength members, or metallic messenger wires — that absolutely must be grounded to prevent electric shock, equipment damage, and fire hazards. While nonarmored fiber optic cables don't require grounding due to their nonconductive properties, grounding is crucial when using armored fiber optic cables. These cables include metallic components that can carry electrical currents, presenting potential hazards such as electrical shock or fire. Fiber optic cable transmits data as light through glass or plastic strands, which means the fiber core itself carries no electrical current and requires no grounding. The critical distinction lies in. This Applications Engineering Note (AE Note) discusses conventional bonding and grounding practices for conductive fiber optic cable and hardware installations within the scope of the National Electrical Code (NEC). In copper cables, bad things happen if we don't do it. • The cables become susceptible to power influence and other external noise issues.
