The module converts 4 input channels of 28Gb/s electrical data to 4 channels of LAN-WDM optical signals and then multiplexes them into a single channel for 112Gb/s optical transmission. On the receiver side, a 112Gb/s optical signal is input into the SOA, and then the module de-multiplexes the signal into 4 channels of LAN-WDM optical signals and then converts them to 4 output channels of electrical data. The central wavelengths of the 4 LAN-WDM channels are 1295.56nm, 1300.05nm, 1304.58nm and 1309.14nm as members of the LAN-WDM wavelength grid defined in IEEE 802.3ba.
The module is a multi-rate optical transceiver with data rate up to 28Gbps per channel. The high-performance cooled LAN-WDM EML integrated TOSA and PIN integrated ROSA with SOA provide superior performance for Telecom and Datacom applications up to 40km links.
