Description
The 200G QSFP-DD 2×CWDM4 Optical Transceiver is a high-density 200Gbps optical module designed to provide two independent 100Gbps Ethernet connections over single-mode fiber. Based on dual 100GBASE-CWDM4 links, it converts eight 25Gb/s NRZ electrical lanes into eight CWDM optical channels and supports transmission distances of up to 2km over G.652 SMF. Dual Duplex LC interfaces provide flexible connectivity for 2×100G network deployments, while the QSFP-DD form factor enables high port density and efficient system integration. The module integrates DFB laser transmitters, PIN photodetector receivers, TX/RX CDR circuits with bypass capability, and CMIS V4.0 management functions for stable operation and convenient monitoring. Compliant with QSFP-DD MSA and CWDM4 MSA specifications, it is suitable for cloud data centers, high-performance computing networks, enterprise infrastructure, and scalable 200G optical deployments.
