    How to connect the grounding wire of a communication optical cable

    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. However, this does not mean every fiber optic installation is exempt from grounding requirements. The grounding point should be selected in a stable, dry, non-corrosive. 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). Let's take a closer look at why grounding matters, the common pitfalls, and how following best practices can keep your system running smoothly. Nowadays, many electrical circuit components, apart from electronic devices, are microprocessor-based and sensitive to electromagnetic disturbances. While electrical services, telecommunications equipment, and all other low voltage systems are required to be bonded to ground per national and local electrical codes and industry standards for safety reasons; the specific need to ground screened and shielded network cabling systems is only a.
