A Brief Overview Of Fiber Optic Splice Closure

The Fiber Optic Splice Closure, also called the fiber optic cable connector box and the barrel, is the place where the end of the optical cable is connected, and then accesses the optical switch through the optical fiber jumper to prevent the aging of materials caused by heat, cold, light, oxygen and microorganisms in nature. And with excellent mechanical strength, the sturdy cable connector housing and main structural components can withstand * harsh environmental changes, while at the same time playing a flame retardant, waterproof, shock, impact, cable tension, distortion and other protection.
According to the structure, the connection box can be divided into two types of optical cable connection boxes: a hat type (vertical type) and a horizontal type (have type). Moreover, when there are certain technical requirements for the design of the optical cable connection box, what technical requirements are there?
The cable connection box can be installed in the overhead, buried, wall and pipe wall of the well; the box seal and the cable inlet and outlet holes are sealed quickly and easily, and can be repeatedly opened and used; the connection box has a good fiber routing design to ensure the radius of curvature of the fiber. The fiber storage space is large; the welding splice tray is selected, suitable for cable or integrated bundled fiber, and can be equipped in any capacity within * 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 structure. The cable is fixed safer and secure; the grounding device and the valve can be installed.

In order to improve the withstand voltage performance of the connection box, 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.

This condition can be increased by at least 100% or more in the case where all other parameters are the same. The connection box is an important part of the optical cable communication line. The main function is to complete the connection of the optical fiber, and to ensure the grounding function of the connection box, the internal grounding device and the grounding part of the optical cable should be in electrical communication, and the metal components of the connecting box and the grounding device and the optical cable reinforcing core are insulated from each other. To prevent the effects of helium from the joint box from the environment.
Because the application environment of the joint box is basically outdoors, their application environment may be buried, overhead or pipeline. Therefore, high requirements are placed on the design of the fixing and grounding device of the connection box and the insulating material used.
