How to connect the grounding wire of the optical cable in a mobile optical distribution box
Run a minimum 14 AWG copper grounding wire (or as specified by local code) from the bonding clamp to the nearest grounding electrode or equipment grounding bus. Keep this conductor as short and direct as possible — avoid sharp bends that increase impedance. Follow these steps at each cable entry point and termination location to achieve a compliant, safe ground bond: Identify metallic components. Strip back approximately 6–8 inches of the outer jacket using a cable slitter or ringing tool. Visually identify armor, strength members, or foil layers. The grounding point should be selected in a stable, dry, non-corrosive. An optical ground wire (also known as an OPGW or, in the IEEE standard, an optical fiber composite overhead ground wire) is a type of cable that is used in overhead power lines.
