The principle and classification of fiber optic connector
2017-12-08

In the optical fiber communication ( transmission ) link, in order to achieve different modules, apparatus and system for flexible connection between the need, it must have a connector, which can be in the optical fiber and optical fiber between the detachable connection device ( movement ), so that the optical paths according to the desired channel for transmission, to realize the predetermined or desired objectives and requirements, to achieve the function of the device is called a connector. Optical fiber connector is the optical fiber end faces of two precision docking, in order to make the transmission optical fiber output energy to maximize receiver coupled to the optical fiber, and the optical link and because of its intervention on the impact of system is reduced to the minimum, which is the basic requirement of optical fiber connector. To a certain extent, fiber optic connectors also influences the optical transmission system reliability and performance.


Optical fiber connection classification


1. Fixedly connected. Mainly used in the optical cable lines between optical fibers permanently connected, by welding, but also have the use of the adhesive and mechanical connection. Characteristics of joint loss of small, high mechanical strength. Equipment need welder, probably tens of RMB.


2. Movably connected. Mainly used for optical fiber and transmission system equipment and instrument connection between, mainly through the optical connector plug connection. Characteristics of joint flexible better exchange connection point, convenient, loss and reflectance is the connection mode is insufficient. Now the insertion loss is also very good, dozens of RMB can be, can buy products directly, if you want to spare parts, also need to face polishing and grinding equipment, that is too expensive, suggest a direct buy jumper.


3. The temporary connection. Measuring and metering fiber pigtail coupling connection, generally using this method connection. Characteristics of low cost, convenient and flexible, the consumption demand is not high, the temporary measure when the use of this connection. Can also be used to weld or V type groove with glue.
