Follow these steps at each cable entry point and termination location to achieve a compliant, safe ground bond: Identify metallic components. Strip back approximately 6–8 inches of the outer jacket using a cable slitter or ringing tool. Visually identify armor, strength. 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). The critical distinction lies in. Protective Earthing is a requirement to divert unwanted, potentially hazardous currents from all exposed metallic parts such as equipment chassis, racks, cabi-nets, cable trays, conduit, and patch panels for personnel safety reasons and to avoid potential damage to equipment. 93 Grounding or Interruption of Non–Current-Carrying Metallic Members of Optical Fiber Cables. There's some confusion over what is meant by "abandoned cable.
