So far, traditional pluggable optical modules have been developed in GBIC, SFP, XFP, QSFP, CFP, OSFP, etc. GBIC is an interchangeable product that meets international standards and can be used as a pluggable adapter, which was the most popular optical module packaging technology before 2000, and then it was replaced by the smaller SFP; the size of the SFP is reduced by half compared to the GBIC, but it can be configured with more than double the number of ports, and the transmission speed covers 1.25/2.5/6Gbps, and the upgraded versions such as SFP+, SFP28, and SFP56 have been introduced. SFP is half the size of GBIC but can be configured to more than double the number of ports, the transmission speed covers 1.25/2.5/6Gbps, and then launched SFP+, SFP28, SFP56 and other upgraded versions, respectively, to support 10, 25, 50Gbps transmission speed; XFP appeared in the SFP + before the transmission rate can also reach 10Gbps; QSFP can support 4-channel transmission, so the transmission rate is four times as high as 40Gbps; QSFP can support 4-channel transmission, so the transmission rate is four times as high as SFP+ and can be up to 40Gbps. QSFP can support 4-channel transmission, so the transmission rate is four times that of SFP and can reach 40Gbps, but the volume is only 30% larger than SFP, and later developed QSFP28, QSFP56, QSFP-DD and other upgraded versions, which can support 100, 200, and 400Gbps transmission speeds; CFP is the packaged form developed for 100 Gigabit Ethernet, with a transmission rate of 40/100 Gbps, and later also developed CFP. CFP is a package developed for 100 Gigabit Ethernet with 40/100 Gbps transmission rate. CFP2, CFP4, CFP8 and other upgraded versions were developed later. CFP2 and CFP4 are 1/2 and 1/4 smaller in size, CFP8 is the same size as CFP2, and it realizes 400 Gbps transmission rate through 16 25 Gbps or 8 50 Gbps interfaces; OSFP is the most recent package, which supports 8-channel transmission and reaches 400 Gbps transmission rate. OSFP is the latest package to support 8-channel transmission to achieve 400Gbps, and is smaller than CFP8 but slightly larger than QSFP-DD.
