The original SFP optical module primarily supports data rates up to 1. 25 Gbps for Gigabit Ethernet and Fibre Channel applications. These transceivers remain widely used for access layer connectivity, legacy backbone links, and specialized industrial equipment. The substantial increase in traffic volume within data centers and backbone networks has driven a surge in demand. An optical module is a typically hot-pluggable optical transceiver used in high-bandwidth data communications applications. Optical modules typically have an electrical interface on the side that connects to the inside of the system and an optical interface on the side that connects to the outside. A 1Mbps optical transceiver is a type of low-speed industrial optical communication module designed not for high-speed Ethernet networks, but for various industrial control systems, serial communication applications, and dedicated equipment data transmission requirements. 1M/100M/155M/622M SFP. With the rapid advancement of AI, HPC, and cloud computing, the demand for high-speed optical modules such as 400G, 800G, and even 1.
