What is the difference between SFP+ and SFP
The difference between SFP+ and SFP. The pinout of SFP and SFP+ connectors are identical. However, SFP is data rate of 6Gb/s, whereas SFP+ is designed for 10Gb/s.
The SFP receptacles and plugs are not as well impedance matched as SFP+ receptacles and plugs.
Also SFP+ cable is designed for 10Gb/s whereas SFP cable may not be able to satisfactorily transmit that rate.
SOPTO 1.25G SFP optic transceiver module is suitable for the application of fiber optical communication whose data rate is less than 1.25G. The 1.25G SFP transceiver module integrates the receiving and transmitting circuits with full metal jacket, plastic tail plug shell and LC interface. The 1.25G SFP optical transceiver module has the function of hot-pluggable, which can be plugged and pulled out in the case of the continuous power supply. The 1.25G SFP transceiver module is suitable for the metropolitan area network. SOPTO offers other SFP module with different data rates, such as 2.5G SFP module, 4G SFP optic transceiver module, etc. In addition, there are many
The Pretty Good SFP Modules Price . Although the same SFP modules and the same manufacturer, the price of the SFP module is different at different time. Of course, the price of the SFP fiber optic transceiver is also affected by other factors. The quality of the Cisco module is better than other manufacturers, but its price is very expensive. Nowadays, there are many equipment manufacturers choose the optical modules with compatibility. The domestic technology has been very mature so that many manufacturers supply these SFP modules. Therefore, it is not problem to the SFP modules with compatibility as long as we choose the right manufacturer. So many users recommend
