The function of the fiber optic splice closure is to connect two optical fiber cables. The fiber optic splice closure is the place where the end of the optical cable is accessed, and then it is connected to the optical switch through the optical jumper. Therefore, the fiber optic splice closure is usually installed on a 19-inch rack, and it can accommodate a large number of fiber optic cable heads. The function of the fiber optic splice closure is to connect two optical fiber cables. Fiber optic splice closure is to connect the fiber optic cable with the pigtail for protection. In actual work, the fiber optic splice closure can be used as an indoor splice box, but the splice case is rarely used as an fiber optic splice closure, and its use is not the same.
Fiber optic splice closures can be divided into optical cable transfer boxes and cable transfer boxes. Their role is to be used for the user's front end wiring.
The main purpose of the fiber optic splice closure is to achieve fiber optic connection. Optical fiber connectors, which are widely used in optical fiber communication systems, have a variety of types and structures. But after careful study, the basic structure of all types of fiber optic connectors is the same, that is, most of the fiber optic connectors generally use high-precision components (composed of two pins and a coupling tube in three parts). Alignment of optical fibers.
This method is to insert and fix the fiber in the pin and polish the surface of the pin to achieve alignment in the coupling tube. The outer components of the pins are made of metal or non-metal materials. The mating end of the pin must be ground and the other end is usually bent to limit the member to support the fiber or fiber optic cable to release the stress.
