General Structure Of Fiber Optic Connector

The main purpose of fiber optic connectors is to realize the splicing of optical fibers. Optical fiber connectors that have been widely used in optical fiber communication systems have many types and different structures. However, upon closer inspection, the basic structure of various types of fiber optic connectors is the same, that is, the vast majority of fiber optic connectors are generally realized by high-precision components (composed of two ferrules and a coupling tube, a total of three parts) Alignment connections for optical fibers.
In this method, the optical fiber is threaded and fixed in the ferrule, and after the surface of the ferrule is polished, the alignment is achieved in the coupling tube. The outer assembly of the contact pin is made of metal or non-metal material. The mating end of the ferrule must be ground and the other end typically has a bend limiting member to support the fiber or fiber optic cable for strain relief. Coupling tubes are generally made of two halves of composite, fastened cylindrical components made of ceramics, or bronze, and are often equipped with metal or plastic flanges to facilitate the installation and fixation of connectors. In order to align the optical fiber as precisely as possible, the processing accuracy of the ferrule and coupling tube is very high.
