Grounding Standard Requirements for Optical Cable Armor Layer
Specifically, NEC Article 770. 100 (A) through (D) outline the grounding and bonding requirements for cables with non-current-carrying metallic components, such as those found in armored fiber optic cables. 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). Be sure to cut at an appropriate length to accommodate the bonding clamp being used. It offers ruggedness and superior crush resistance. Fiber optic cables consist of.
