Standard Requirements for Grounding of Power Optical Cables
Industry standards such as the NEC (National Electrical Code) Article 770 and NFPA 70 provide binding requirements, while standards from IEEE and TIA offer additional guidance. 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). Any cable that includes any conductive metal must be properly grounded and bonded in conformance with the. 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. NEIS® are intended to be referenced in contrac documents for electrical construction ation or liability to users of this publication. During installation, all curvatures should be smooth.
