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.
10G multi-mode short-distance XENPAK module . The XENPAK-10Gb-SR module belongs to the series of Cisco. From the models of the module, we know that the data rate of this XENPAK-10Gb-SR module is 10Gbp/s. The “SR” indicates that it is a multi-mode and short-distance transmission XENPAK optical module whose wavelength is 850nm and transmission distance is 300m. Furthermore, one thing to note is that the Cisco series of the XENPAK module is SC interface. The XENPAK-10Gb-SR fiber optic transceiver is widely applied in 10G Ethernet. With the rapid development of the communications revolution, SOPTO dedicates in the field of optoelectronic devices, painstaking
The Cisco XENKAP with high heat-dissipation performance . From the end user's perspective, the main difference between Cisco XENPAK, X2, XFP is the mechanical dimensions, supporting port-types and 10G protocol (except for 10GE). The Cisco XENPAK is the largest module among these three fiber optic modules. And the Cisco XENPAK module has a multi-functional advantage because of its increased size. From example, more space benefits to the integrated optical networks and electronic components. They will have higher heat-dissipation efficiency and reduce the demand of heat-dissipation. Therefore, Cisco XENPAK supports the widest range of port-types to meet the needs of
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
