Optical fiber connector refers to the removable, movable and repeatedly inserted connecting device that connects one optical fiber to another optical fiber and also known as optical fiber movable connector.It can realize low loss connection between optical fiber or between optical fiber and cable and effectively reduce the influence of optical fiber connection on signal.Optical fiber connector is mainly composed of four parts: pin, connector body, optical cable and connection device.
Fiber optic connectors need to meet many requirements in terms of characteristics, including the insertion loss of fiber optic transceivers less than 0.5dB and return loss greater than 25dB.The tensile strength of optical fiber connector is greater than 90N.The operating temperature range of optical fiber transceiver is -40℃~70℃, and the frequency of plugging and unplugging is more than 1000 times.
According to the different transmission media, optical fiber connector can be divided into single-mode optical fiber connector and multi-mode optical fiber connector.According to the connector structure.It can be divided into LC fiber connector, SC fiber connector, FC fiber connector, ST fiber connector, MPO/MTP fiber connector, mt-rj fiber connector, MU fiber connector, DIN fiber connector, E2000 fiber connector and so on.
LC optical fiber connector is developed by bell research institute. The size of its pin and sleeve is 1.25mm, which is half of SC/FC optical fiber transceiver. It adopts the latch fastening mode of socket (RJ) and is generally applied to high-density optical fiber distribution frame.
The SC fiber optic connector is developed by NTT company in Japan. Its shell is rectangular, the pin size is 2.5mm, and the bolt is fastened by the plug and pull pin. The insertion method is simple and convenient.
FC fiber optic connector is also developed by Japanese NTT company, and the pin size is 2.5mm. However, the pin size of FC fiber optic connector is relatively short, and its surface adopts metal sleeve and screw fastening mode. The biggest feature of this fiber optic connector is that it is not easy to fall off after installation.
MPO/MTP fiber connector is a kind of fiber connector specially made for multi-fiber ribbon cable, with 4/6/8/12/24 core and other kinds of fiber models. MPO/MTP fiber connector has the characteristics of small size and many cores, generally used in high-density fiber link.
MPO/MTP fiber connector is a kind of fiber connector specially made for multi-fiber ribbon cable, with 4/6/8/12/24 core and other fiber models. MPO/MTP optical fiber connector has the characteristics of small size and large number of cores, which is generally used in high-density optical fiber links.
In the connector use, it is very important to clean the connector end face, so as to ensure the connector to maintain a better working state.The commonly used cleaning method of the end face of optical fiber connector is contact type and non-contact type.As an indispensable component in the integrated wiring project, optical fiber connector, though small, makes a great contribution to the whole network.
