  • Lightning protection and grounding of fiber optic cable junction box

    Lightning protection and grounding of fiber optic cable junction box

    After fiber optic cables enter the fiber optic terminal boxes, the boxes should be connect to the ground so they can rapidly release the lightning current to realize the protection when the lightning current enter the fiber optic cables' metal layers. The major purpose of lightning protection systems is to conduct the high current lightning discharges safely into the Earth/ground. Since the lightning. Lightning Protection for Direct-Buried Fiber Optic Cables Station Grounding Method: the metal part of the cables in the joints should be all connected to make sure the strengthened cores, moistureproof layers, and armoured layers are in connected state in the relay cable lines. These solutions use two ways of grounding for optical cable links both in domestic and foreign standards.
