  • Fiber Closure'S Moisture Barrier And Arrester

    Fiber Closure are commonly used for outdoor cables; they provide a splicing space for outdoor fiber optic cables. The fiber optic connector enclosure and internal fiber optic tray will protect the splice portion of the splice fiber and the outdoor fiber optic cable. Typically, fiber optic connector closures are dome and horizontal. Dome fiber optic connector closed cables are generally divided into two types, one is heat shrink type, and the other is mechanical seal type. The type of heat shrinkage means that the heat shrink tubing is achieved by a seal between the cable and the cable. The type of mechanical seal, the cable and cable are removed from the pipe by deformation of the seal ring cable. The mechanical means is to compress the seal ring and fill the cable between the cable and the cable.

    It is used for fiber optic cable closure in fiber optic cable to adapt to local conditions such as weather and terrain. Through the analysis of the fiber dome closure in recent years, it is found that the structure and maintenance of the fiber joint should pay attention to the following problems.

    The fiber optic closure is usually closed with a reinforcing core, the connection of the metal plate is better than the bolt connection, and the horizontal opening of the bolt is superior to the vertical slotted structure, which is a problem of selection of the optical fiber connector. The air fiber optic connector closes the metal parts and should be grounded every 2 km. The grounded metal parts are grounded directly or through proper surge protection. The steel strands have the protection of overhead ground wire.

    For cable grounding in telecommunications offices, the metal portion of the cable in the fiber enclosure should be connected and the core, moisture barrier and armor layer attached and held. At the end of the unit (station) armor layer, the reinforcing core should be grounded and the moisture barrier layer grounded through the arrester. For optical cables without copper wire, according to YDJ14-91, in the moisture-proof layer of the cable, the protective layer and the reinforcing core should be broken, not grounded, grounded and insulated, to avoid lightning current accumulated in the cable. Practice has proved that this method is simple and effective. Generally, the insulation value of the optical fiber cable in the metal component is high, and the lightning current is not easy to enter the optical cable, so as to avoid damage to the connector protection cable.
