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.
How to buy the cheap XENPAK-10GB-LR module ? The XENPAK-10GB-LR is also the fiber optic transceiver which belongs to the series of Cisco. Compared with the XENPAK-10Gb-SR module, their data rate is both 10Gbps and XENPAK-10GB-LR and ENPAK-10Gb-SR are both SC interface. However, the working wavelength of XENPAK-10GB-LR is 1310nm and the transmission distance is 10km which is much longer than XENPAK-10Gb-SR module. In addition, the XENPAK-10GB-LR is the single-mode optical module. Of course, since the data rate is 10G, the XENPAK-10GB-LR also can be used in 10G Ethernet. Currently, the price of the XENPAK-10GB-LR module is different in the market. Usually, we need to
There are a variety of ways to classify SFP fiber optic transceiver according to each parameter of the SFP module. Firstly, SFP fiber optic modules can be divided into 155M, 622M, 1.25G, 2.5G and 4G optic modules according to the data rate. Secondly, if according to the working wavelength, there are 850nm SFP modules, 1310nm SFP modules, 1490nm SFP fiber optic transceiver and 1550nm SFP modules commonly. Thirdly, SFP fiber optic modules also can be divided into LC SFP modules, SC SFP modules and RJ45 SFP modules according to the types of interfaces. Lastly, we will classify many types of SFP modules on the basis of the transmission distance from 550nm to 120km.
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
