Methods for grounding optical cable sheath
Grounding the shield at only one end of the cable is the long-established best practice. 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). Grounding is classified into three different types: protective grounding, operational grounding, and lightning grounding. 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. Interlocking armor is an aluminum armor that is helically wrapped around the cable and found in indoor and indoor/outdoor cables.
