Dell Q56DD-400G-SR8 Compatible 400G QSFP-DD SR8 PAM4 850nm MTP/MPO-16 OM3/OM4 100m DDM/DOM with FEC Optical Transceiver Module
Dell Q56DD-400G-SR8 Compatible 400G QDD SR8 is a high-performance, cutting-edge transceiver that delivers up to 70m on OM3 or 100m on OM4. It is compliant with IEEE P802.3bs, RoHS, and is capable of reaching up to 100m via MTP/MPO-16 connectors. This transceiver is designed to support PAM4 and 400GAUI-8/CEI-56G-VSR-PAM4, and is compliant with the MSA (Multi-Source Agreement), which is ideal for all your data center needs. Get the most out of your Ethernet networks with the 400G QDD SR8.
400G QDD SR8 meets the 200G QSFP56 switch/NIC interconnection solution and also supports interconnection with 2x200G QSFP112 NICs, effectively enabling a smooth network upgrade from 200G to 400G.Under the same network architecture of NIC-to-switch and switch-to-switch connections, offers a lower cost than 400G QDD SR4.
400G QDD SR8 delivers up to 100m transmission distance, enabling high-speed interconnects between adjacent racks and supporting horizontal scaling for AIDC (AI Data Center) /DCN (Data Center Network).
NADDOD 400G optical transceiver has great advantages in increasing data throughput and maximizing data center bandwidth and port density. 400G QSFP-DD has been tested and recognized by the global market as we are the first brand to complete the commercial order delivery of 400G data center optical modules.
NADDOD has a full range of professional testing equipments for testing various parameters of products to ensure high performance and quality of optical transmission stability.
