Description NADDOD NVIDIA/Mellanox compatible QDD-800G-2xDR4 is an 800G QSFP-DD optical transceiver based on PAM4 modulation, integrating two independent 400G DR4 optical channels within a single module. Each 400G channel delivers 4×100G PAM4 transmission over an MPO-12 interface, enabling an aggregate throughput of 800Gb/s.
Designed for switches with 800G QSFP-DD ports, the QDD-800G-2xDR4 supports flexible connectivity to either a native 800G optical module or two 400G DR4 QSFP-DD modules using MPO-12 APC fiber cabling, making it well suited for high-density data center and AI network deployments.
