Technical advantages of the 25G SFP28 optical module. What are the common 25G SFP28 optical modules?

The 25G optical module belongs to the low-speed optical module in the optical module market. The appearance of the 25G optical module compensates for the defect that the high-speed optical module is too expensive and the 10G optical module cannot meet the user's demand. So, what are the technical advantages of the 25G SFP28 optical module? What are the common 25G SFP28 optical modules? In this article, infiberone mall will give you a detailed introduction.

The 25G SFP28 optical module is an optical module with a transmission rate of 25 Gbps. It is mainly used for interconnection of data center servers and switches. It is a new Ethernet standard with various advantages. It was proposed by the IEEE 802.3 working group in July 2014. And in June 2016, all revisions were completed. The biggest advantage that 25G Ethernet technology brings to the data center is the ability to maximize bandwidth and port density, and it can also achieve 100Gb data transmission with 25Gb/s single-channel physical layer technology, and it can provide the most energy-efficient Ways to meet the growing demand for next-generation data center networks.

Why is the 25G SFP28 optical module complementary to the 10G optical module rate and the 100G optical module rate?

Because the optimal input/output (I/O) performance and fiber capacity of a 25G SFP28 optical module is 2.5 times that of 10G Ethernet and has a higher port density, it can also save operations by reducing the number of ToR switches and cables. cost. Compared with 100G optical modules, the loss of 25G SFP28 optical modules is also smaller. In addition, the 25G SFP28 optical module can use 2 fiber channels to achieve 50G transmission rate. Compared with 4 10G fiber channels for 40G optical modules, the 25G SFP28 optical module is a better choice.

Through the above, we already know the birth and advantages of the 25G SFP28 optical module. So, what are the common 25G SFP28 optical modules? Please continue to look down.
