Available Options
JTOPTICS® 100Gbps transceiver module designed for optical communication applications compliant to 100GBASE-ER4. The module converts 4 input channels of 25Gb/s electrical data to 4 channels of LAN WDM 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 LAN WDM optical signals and then converts them to 4 output channels of electrical data. The high-performance cooled LAN WDM EML transmitters and high sensitivity PIN+SOA receivers provide superior performance for 100Gigabit Ethernet applications up to 40km links and compliant to optical interface with IEEE802.3ba 100GBASE-ER4 requirements
