With single-ended grounding, it is usually better to ground the cable shield at the source end, because that is the reference for the signal voltage. 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. Any cable that includes any conductive metal must be properly grounded and bonded in conformance with the. Optical cable grounding is an important measure to protect optical cables and their connected equipment from lightning strikes, electrostatic discharge and electromagnetic interference. Here. One end grounded = stable, quiet, reliable. Surge protection with GDT = the best of both worlds. The Basics: Why Grounding Is Important Shielded twisted-pair cables are designed to keep external electrical noise such as electromagnetic. 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). No practical shield provides magnetic-field protection at low frequency.
