When installing any fiber optic system, it is necessary to consider connecting the optical fiber or the cable to each other in a low-loss manner to realize the connection of the optical link. Fiber-optic link of the connection, but also can be divided into two kinds of permanent and active. Permanent connection, mostly using fusion, bonding or fixed connector to achieve; active connection, the general use of the active connector to achieve this article will be a brief introduction to the active connector.

Fiber optic connectors, commonly known as live connectors, commonly known as fiber optic connectors Fiber optic connectors offer, parameters, pictures, group music, is used to connect two optical fibers or fiber optic cable to form a continuous optical path can be reused passive devices, Widely used in optical fiber transmission lines, fiber optic patch panels and fiber test equipment, instruments, is currently the largest number of optical passive devices.

The general structure of the fiber optic connector

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 structure. 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 accuracy is very high.
