This 100Gb/s transceiver module is designed for optical communication applications, fully compliant with the IEEE P802.3. It converts 4 channels of 25Gb/s electrical data into LAN WDM optical signals for 100Gb/s transmission over distances of up to 10km. On the receiver side, it de-multiplexes the 100Gb/s optical input into 4 electrical channels. The module features cooled LAN WDM DFB transmitters and high-sensitivity PIN receivers, ensuring superior performance. Designed according to QSFP+ MSA, it meets stringent requirements for temperature, humidity, and EMI interference, making it ideal for 100Gigabit Ethernet applications.
