General requirements for fiber optic splice closure operation! The role of the fiber optic splice closure is to measure the transmission characteristics (program, end) of the fiber. The fiber is inspected and recorded in the inspection of the insulation resistance joint of the sheath to the ground, and is recorded in the vehicle or joint tent. In order to prevent the pollution of dust and harmful gases (Freon), the ambient temperature should be ≧0°.
In order to ensure the softness of the fiber and the normal operation of the welding equipment, the remaining fiber length should be 4m, and the final excess length of the fiber in the joint sheath≧ 60cm, it is necessary to work continuously as much as possible. Otherwise, it should be protected from moisture and safety. After the fiber is welded, the joint loss must be measured. After passing the package protection tube, the joint pit of the directly buried fiber should be located on the right side of the route A→B. Otherwise, mark the left side on the route construction drawing.
Overhead—The connector is mounted next to the pole for telescopic bending. The remaining length of the joint is placed on the adjacent rod after being placed. The pipe-joint box is installed at a higher position in the entrance hole and is immersed in the water in the hole during the rain-proof season.
Fiber optic splice closure sheathing—cutting the inner and outer sheaths of the end portion of the fiber to be connected, the fiber of the butt fiber, the reinforcing core, the metal wire and the metal sheath, and then the joint sheath (the joint box (box), sub-shell [ Seal], the support member [the skeleton of the receiving box, including the bracket, the fiber fixing clip and the light receiving plate] and the connecting member integrally protect and seal the fiber joint portion.
