What is the structure of fiber optic connectors in general use

Fiber optic connector, is a removable (movable) connection between the optical fiber and the optical fiber, it is the two end faces of the optical fiber precision butt joints, in order to make the transmitter optical fiber output light energy can be coupled to a greater extent to the receiving fiber, and make its intervention in the optical link and the impact on the system caused by the minimum, which is the basic requirements of the fiber optic connector. To a certain extent, the fiber optic connector affects the reliability and performance of the optical transmission system. What is the structure of fiber optic connectors in general use? The main purpose of fiber optic connectors is to realize the splicing of optical fibers. Fiber optic connectors have been widely used in fiber optic communication systems, there are many types of fiber optic connectors with different structures. However, in detail, the basic structure of various types of fiber optic connectors is the same, that is, the vast majority of fiber optic connectors generally use high-precision components (consisting of two pins and a coupling tube composed of a total of three parts) to achieve optical fiber alignment connection. This method is the optical fiber into and fixed in the pin, and the surface of the pin is polished, in the coupling tube to achieve alignment. The outer components of the pins are made of metallic or non-metallic materials. The butted end of the pin must be lapped, and the other end typically employs a bend-restricting member to support the optical fiber or fiber optic flexible cable to relieve stress.
