A fiber optic connector is a detachable, removable, re-plugged connection device that connects one fiber to another, also known as a fiber optic splice. It enables low-loss connections between fibers or between fiber and cable, effectively reducing the impact of fiber connections on the signal. The fiber optic connector is mainly composed of four parts: a pin, a connector body, an optical cable, and a connecting device.
Fiber optic connectors need to meet many requirements in terms of characteristics, including fiber optic transceiver insertion loss of less than 0.5dB, return loss greater than 25dB; fiber optic connector tensile strength greater than 90N; fiber optic transceiver operating temperature range of -40 ° C ~ 70 ° C, more than 1000 insertions and so on.
Depending on the transmission medium, the fiber optic connector can be divided into a single-mode fiber connector and a multi-mode fiber connector; and depending on the connector structure, it can be divided into an LC fiber connector, an SC fiber connector, and an FC fiber connector. ST fiber optic connector, MPO/MTP fiber optic connector, MT-RJ fiber optic connector, MU fiber optic connector, DIN fiber optic connector, E2000 fiber optic connector, and the like.
The LC fiber optic connector was developed by Bell Labs. Its pin and sleeve are 1.25mm in size and are half of the SC/FC fiber optic transceiver. Jack (RJ) latch-fastening is used for general applications. On high-density fiber distribution frames.
The SC fiber optic connector was developed by NTT Corporation of Japan. Its outer casing is rectangular and the pin size is 2.5mm. It is fastened by plugging and unplugging. The insertion method is simple and convenient.

The FC fiber optic connector was also developed by NTT Corporation of Japan, with a pin size of 2.5 mm. However, the FC fiber connector has a relatively short pin, and the surface is made of a metal sleeve and a screw-fastening method. The biggest feature of the device is that it is not easy to fall off after installation.

MPO/MTP fiber optic connector is a fiber optic connector specially designed for multi-fiber ribbon cable. It has 4/6/8/12/24 core and other fiber models. MPO/MTP fiber connector has small size and core. A number of features, etc., generally used in high-density fiber links.

In the use of the connector, it is very important to clean the end face of the connector to ensure that the connector maintains a better working condition. Commonly used cleaning methods for fiber optic connector end faces are contact and non-contact. As an indispensable device in the integrated wiring project, the fiber optic connector is small, but has contributed greatly to the entire network.
