Description NADDOD Arista QDD-400G-DR4 compatible 400G QSFP-DD DR4 optical module adopts a 1310 nm EML transmitter and PAM4 pulse amplitude modulation. It supports transmission distances of up to 500 m over OS2 single-mode fiber and features an MTP/MPO-12 connector. The module is compliant with the QSFP-DD MSA, IEEE 802.3bs, and 400GBASE-DR4 standards, ensuring broad interoperability.
The 400G QSFP-DD DR4 module is designed for 400G Ethernet data communications. It is typically used to interconnect NVIDIA ConnectX-7 OSFP-packaged 400G NICs with 400G QSFP-DD switches and can also be used as a 4×100G breakout to QSFP-DR 100G. Its combination of low latency and high bandwidth makes it ideal for AI and HPC data center interconnects, cloud networking, and other high-performance computing applications.
