Compact And Mini Type Fiber Optic Termination Box 6 To 24 Fibers SC And ST

FA-FDTWFM12G , Compact And Mini Type Fiber Optic Termination Box 6 To 24 Fibers SC And ST

With the development of the network, as a medium for data transmission in integrated cabling system, because it has the advantages of high transmission speed and long distance, optical fiber is more and more popular. As everyone knows, fiber is not conductive, it can be free from the impact of current, and the optical fiber cable also has good protective properties, metal components in fiber cable is with excellent ground insulation so lightning current is not easy to enter the optical cable, but since the fiber optic cable is with strengthen member, especially the buried fiber cable is with armored layer, so when the optical fiber cable meets lightning, it may be burned or damaged.

A, for direct buried fiber cable: 1, on the grounding mode: metal parts in cable joints should be connected, like strengthen member, moistureproof layer, armored layer of the fiber cable must be connected. 2, in accordance with the provisions of YDJ14-91, moistureproof layer, armor layer and strengthen member in optical fiber cable should be electrically disconnected, not grounded and insulated, such as can avoid the lightning current accumulation in the cable and also can be avoided lightning current come into the optical cable by grounding device due to lightning drain wire and loop impedance difference of metal components.

B, for overhead optical cable: overhead messenger must be electrical connected and grounded every 2km, grounding directly or through a surge protection device which is suitable for grounding. Such an overhead hanging messenger is with ground wire protection.

C, after the fiber optic cable come into the fiber terminal box, fiber optic terminal box should be grounded so when the lightning current come into the metal layer of the fiber cable, terminal box grounding can quickly release the lightning current and play a protective role. The direct buried optical cable has armored layer and reinforced core, and the outer sheath is PE (polyethylene) sheath, which can effectively prevent corrosion and prevent mouse bite.
