[pdf] 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. 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). These cables include metallic components that can carry electrical currents, presenting potential hazards such as electrical shock or fire. Is there any NEC / NESC or other requirement to ground/bond the tracer wire on communication wire on one end (Fiber in this case)? There is a 138kV transmission line near a large solar farm and a 7. 62kV distribution line running parallel about 50ft away serving residential power.
