What Is SFP Module?
fiber SFP types means small form-factor pluggable. It's a compact and hot-pluggable transceiver which is commonly used in telecommunication and data communication. SFP is often called mini-GBIC (Gigabit Interface Converter). It is with a smaller size and it has already taken the place of GBIC modules in most 1Gb applications. Currently, most SFP module types is fiber optic SFP types and most of them are used for gigabit and 10G devices. 100M SFP modules are still in some needs, but it's decreasing. Optical SFP modules are designed with a wide range of transmitters and receivers for multiple distance needs. They are also applied with various wavelengths to meet different optical signal transmission. There are also SFP modules designed for Ethernet ports, they can convert fiber ports into RJ45 ports.
