The module converts 4 input channels of 25Gb/s electrical data to 4 channels of CWDM optical signals and then multiplexes them into a single channel for 100Gb/s optical transmission. Reversely on the receiver side, the module de-multiplexes a 100Gb/s optical input into 4 channels of CWDM optical signals and then converts them to 4 output channels of electrical data. The central wavelengths of the 4 CWDM channels are 1271nm, 1291nm, 1311nm and 1331nm as members of the CWDM wavelength grid defined in CWDM4 MSA. The high-performance uncooled CWDM DFB transmitters and high-sensitivity PIN receivers provide superior performance for 100-Gigabit Ethernet applications up to 10km links.



Data center Ethernet requirements are driven by two of the most important considerations: energy efficiency and cost. Areas related to data center development include the development of the cloud and the Leaf/Spine matrix network architecture. As to further improve the server performance, also as within the data center from the leaf to the spine, and upgrade to 100GBPS layer connection in the server from the existing 10GBPS to 25GBPS / 50 GBPS upgrade has very realistic significance: because 10 g Ethernet speed standards often can't meet the demand, and 100g is too expensive, the emergence of 25g and 50g Ethernet standard is just made up for the inadequacy of the two. In addition, 25Gbps and 50Gbps per channel technologies will be the basis of future 100Gbps(4 25Gbps) and 400Gbps(8 50Gbps) Ethernet standards, so the industry is generally looking to use 25G transmission rates to replace the current 10Gbps rates.
