Optical Fiber Connector The Main Purpose Is To Achieve The Connection Of Optical

The optical fiber connector is a detachable (active) connection between the optical fiber and the optical fiber, which precisely interfaces the two end faces of the optical fiber so that the light energy output from the emitted optical fiber can be coupled to the receiving fiber to the maximum, And to minimize the impact on the system due to its involvement in optical links, and can be divided into common single-mode and multi-mode connectors for silicon-based fibers, depending on the transmission medium.

The main purpose of fiber optic connectors is to achieve fiber connections. Now widely used in optical fiber communication system in the optical fiber connector, its many types, different structures. However, the basic structure of various types of fiber optic connectors is consistent, that is, the vast majority of fiber optic connectors generally use high-precision components (by two pins and a coupling tube composed of three parts) Alignment of the fiber.

This method is to penetrate and fixed the fiber in the pin, and the pin surface after polishing, in the coupling tube to achieve alignment. The outer part of the pin is made of metal or nonmetal material. The butt end of the pin must be ground and the other end usually uses a bend limiting member to support the fiber or fiber optic cable to release the stress. The coupling pipe is usually made of ceramic, or bronze and other materials made of two semi-synthetic, fastened cylindrical components made of multi-metal or plastic with a flange, in order to facilitate the installation of the connector fixed. In order to precisely align the fiber, the pin and the coupling pipe processing precision is very high.

The optical fiber connector is a detachable (active) connection between the optical fiber and the optical fiber, which precisely interfaces the two end faces of the optical fiber so that the light energy output from the emitted optical fiber can be coupled to the receiving fiber to the maximum, And minimizes the impact on the system due to its involvement in optical links, which is a fundamental requirement for fiber optic connectors. To a certain extent, fiber optic connectors affect the reliability and performance of optical transmission systems.

Optical fiber connector according to the different transmission medium can be divided into common silicon-based fiber single-mode and multi-mode connector, there are other such as plastic as the transmission medium of the fiber connector; according to the connector structure can be divided into: FC , SC, ST, LC, D4, DIN, MU, MT, and so on. Among them, ST connectors are usually used for wiring equipment, such as fiber patch panels, fiber optic modules, etc .; and SC and MT connectors are usually used for network equipment. According to the shape of the fiber end points are FC, PC (including SPC or UPC) and APC; according to the number of optical fiber is divided into single and multi-core (such as MT-RJ) points. Fiber optic connectors are widely used and varied. In the practical application process, we generally in accordance with the different structure of the fiber connector to be distinguished. It is divided into FC type fiber optic connector, SC type optical fiber connector, double cone type connector, MT-RJ type connector, LC type connector, MU type connector and MC connector.
