Position the base of the grounding clamp under the armor. Place the ring terminal on the ground wire over the stud with the ground wire. 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. Additionally, the phase sequence, arrangement, and installation type of cables are crucial factors. The main ones. Cable shields and the metallic sheaths or armors need to be solidly grounded on at least one point in order to operate at or near ground potential at all times. Dielectric-armored cable options exist that offer the required protection without the hassle of. Optical cable grounding is an important measure to protect optical cables and their connected equipment from lightning strikes, electrostatic discharge and electromagnetic interference.
