SFP optical module package because of the different ports, into RJ45 (COPPER SFP) and SFP. The optical port optical module is RJ45, and the optical port module is called SFP, which is a general SFP.The most common module involved in network communication is the SFP of the optical port, not the
RJ45 (COPPER SFP).Because in a Gigabit Ethernet switch, the SFP port complies with the 1000BASE-T (IEEE 802.3ab) standard and the transmission rate can reach 1000 Mbps. When using the RJ45 port, the SFP optical module must be inserted in the switch first, and then the network cable (Category 5/Super 5/6 network cable) can be used for data transmission.
It can be seen that directly using the SFP port will make the transmission more convenient and save more conversion network cables and modules. When purchasing accessories, you can save a lot of unnecessary costs and save a lot of space.
In addition, the SFP connection requires two SFP electrical port optical modules and one Category 5 network cable, or two SFP optical port optical modules and one fiber patch cord. The RJ45 connection only needs to use a Category 5 network cable.The Cooper SFP must be worn with a network cable.The SFP is paired with fiber optics, and the accessories are different. In order to convert the RJ45 to the SFP port, the converter is required to assist.
Finally, in data center, local area network (LAN) and other applications, the switch's SFP port also has 100/1000Mbps adaptive function.
Based on the above, we found that the performance of the RJ45 port and the SFP port are basically the same, except that the transmission and conversion are different. From a cost perspective, the wiring cost of the SFP port is higher.However, the SFP port still exists, and its utilization rate in real life is particularly high. Because it can support not only SFP electrical port module and SFP optical port module, but also the transmission distance of SFP optical port optical module is farther than RJ45 port, it has higher flexibility in practical applications, so it can be expanded. Sex is also relatively high.
Fiberland Ltd. is currently selling copper SFP and SFP. Currently, the specifications of the cooper SFP are 10/100/1000M and 10G. For more information, please contact us.
