Home / How long should an optical cable be for grounding
This pattern is large, at least 10-20 feet from top to bottom of the pattern. 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). Proper grounding methods can significantly improve the stability and safety of fiber optic cable systems. Since an optical fiber cable is non-conductive and there is no electric flowing, there are several advantages over a twisted copper cable in deploying: The non-conductive (dielectric) characteristics of fiber impacts how a designer lays out cabling pathways.
So many communications cabling workers do not see the necessity of grounding fiber-optic cable, but codes on both sides of the U.S./Canada border agree that any cable containing metal must be
