The fiber optic splice closure is divided into two types of fiber optic splice closures: a split-type (vertical) and a horizontal (huff type).
It can be installed in overhead, buried, wall and pipeline manhole wall; box seal and cable access hole sealing is quick and simple, can be repeatedly opened and used; good fiber routing design ensures fiber radius of curvature, fiber storage space is large; The splice tray is suitable for cable or integrated bundling fiber, and can be arbitrarily configured within the maximum capacity. The splice disk has large storage space, the flip angle is greater than 90°, and the maintenance and expansion are convenient; the internal cable is fixed and the cable is safer and more reliable; Grounding devices and valves can be installed.
In order to improve the withstand voltage performance of the fiber optic splice closure, it is necessary to use a better insulating material to increase the surface finish and reduce the curvature between the insulator and the pole and pole and between the pole and the ground. In the case where all other parameters are the same, this case can be increased by at least 100% in length.
The fiber optic splice closure is an indispensable part of the optical cable communication line. The main function is to realize the connection of the optical fiber cable, and at the same time, to ensure the grounding function of the fiber optic splice closure, the internal grounding device and the grounding part of the optical cable should be in electrical communication, and the metal component of the fiber optic splice closure and the grounding device and the optical cable reinforcing core are ensured. They are insulated from each other to avoid adverse effects from the environment on the fiber splice closure.
Since the use environment of the fiber optic splice closures is basically outdoors, their use environment may be buried, overhead or pipeline. Therefore, high requirements are placed on the design of the fixing and grounding device of the fiber optic splice closure and the insulating materials used.
