100G QSFP28 CWDM4 2KM optical transceiver is a high-speed QSFP28 module compliant with the 100GBASE-CWDM4 standard. It enables 100Gbps Ethernet data transmission over single-mode fiber (SMF) for distances up to 2 kilometers. Utilizing Coarse Wavelength Division Multiplexing (CWDM) technology, it multiplexes and demultiplexes signals on four specific wavelengths (1271nm, 1291nm, 1311nm, 1331nm). This module provides a cost-effective solution for data center interconnects (DCI) and metro access networks.
