Use a grounding wire: Use a dedicated grounding wire to connect the metal reinforcement core or armor layer in the optical cable to the grounding electrode or the building's grounding system. The cross-sectional area of the grounding wire should be large enough to ensure a. 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). This AE Note does not address outside plant fiber optic installations or. 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. As we enter 2024, adhering to best practices not only enhances system reliability but also mitigates potential issues that can affect customer experiences. 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.
