The main purpose of the optical fiber connector is to achieve the splicing of the optical fiber. Optical fiber connectors have been widely used in optical fiber communication systems, and there are many types and different structures. But on a closer look, the basic structure of various types of optical fiber connectors is the same, that is, most optical fiber connectors generally use high-precision components (consisting of three parts consisting of two pins and a coupling tube) to implement optical fiber Alignment connection.
In this method, an optical fiber is inserted into and fixed in a pin, and the pin surface is polished to achieve alignment in a coupling tube. The outer component of the pin is made of metal or non-metal material. The mating end of the pin must be ground, and the other end usually uses a bending control member to support the optical fiber or optical fiber cable to relieve stress. The coupling tube is generally made of two halves of ceramic, bronze, and other composite, fastened cylindrical members. Most of them are equipped with metal or plastic flanges to facilitate the installation and fixation of the connector. In order to align the fiber as much as possible, the processing accuracy of pins and coupling tubes is very high.
