With the development of science and technology and the construction of 4G network, the requirements for transmission rate are getting higher and higher, and people's speed of signal network is getting higher and higher. Therefore, there is a need for a high-speed transmission equipment product, which results in a 10G optical module. Many people are actually relatively unfamiliar with optical modules. In short, an optical module is an integrated optical transceiver module consisting of optoelectronic devices, functional circuits and optical interfaces, including transmission and reception. That is, an integrated optical transceiver module. To put it bluntly, the optical module is the conversion of electricity to light. Optical-to-electrical electronic products can convert signals into optical signals, making the transmission distance more transportable. So what are the types of optical module fiber interfaces?

　　1. Liquid level connector.

　　Duplex LC connector.

　　Duplex LC connectors are suitable for the connection of dual-fiber optical modules, such as 1.25 gigabit dual-fiber optical modules, 10g 10G dual-fiber optical modules, 25g dual-fiber optical modules, 40g/100g single-mode, etc.

　　Single station connector.

　　Simplex LC connectors for single-fiber optical modules, such as 1.25g gigabit single-fiber LC interface optical modules (with SC interface and LC interface), 10g 10-gigabit single-fiber optical modules, 25g single-fiber optical modules, etc.

　　2. SC connector.

　　SC connectors are mainly used for the connection of monofilament bidirectional optical modules, such as 1.25g gigabit fiber SC interface optical modules.

　　3. MPO connector.

　　MPO connectors are used to connect 40G/100G optical modules such as 40GSR4.100GSR4. MPO connectors are available in 8-core, 12-core, 24-core and other specifications, and are generally used for 40GSR4.100GSR4 and 12-core fiber optic patch cords.
