What are the main functions of huawei fiber optic connectors

Huawei fiber optic connectors are devices for detachable (movable) connections between optical fibers. It precisely butts the two end faces of optical fibers so that the optical energy output by the transmitting optical fiber can be coupled into the receiving optical fiber to the maximum extent. , and minimize the impact on the system due to its intervention in the optical link, which is the basic requirement of fiber optic connectors. To a certain extent, fiber optic connectors also affect the reliability and performance of optical transmission systems.

Huawei fiber optic connectors can be divided into common silicon-based optical fiber single-mode and multi-mode connectors according to different transmission media, and other optical fiber connectors such as plastics as transmission media; according to the structure of the connector, it can be divided into: Various forms such as FC, SC, ST, LC, D4, DIN, MU, MT, etc. Among them, ST connectors are usually used at the wiring equipment end, such as optical fiber distribution frames, optical fiber modules, etc.; while SC and MT connectors are usually used at the network equipment end. According to the shape of the fiber end face, there are FC, PC (including SPC or UPC) and APC; according to the number of fiber cores, there are single-core and multi-core (such as MT-RJ). Fiber optic connectors are widely used and come in many varieties.

The main purpose of huawei fiber optic connectors is to realize the connection of optical fibers. Now, the 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 structures of various types of fiber optic connectors are consistent, that is, most fiber optic connectors generally use high-precision components (composed of two pins and a coupling
The tube consists of three parts) to realize the alignment and connection of the optical fiber. In this method, the optical fiber is passed through 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 members made of materials such as ceramics or bronze, and are often equipped with metal or plastic flanges to facilitate the installation and fixing of connectors. In order to align the optical fiber as accurately as possible, the optical fiber connector requires high processing accuracy of the ferrule and the coupling tube.
