Generic Compatible 400GbE QSFP-DD SR8 PAM4 FEC Optical Transceiver Module (850nm 100m MMF MTP/MPO )
NADDOD Generic compatible 400G QSFP-DD SR8 is a short-reach multimode optical transceiver designed for 400 Gigabit Ethernet data center interconnects. It supports transmission distances of up to 70m over OM3 and 100m over OM4 multimode fiber, using MTP/MPO-16 connectors. The module is compliant with IEEE P802.3bs, RoHS, and relevant MSA specifications, ensuring broad interoperability. Based on PAM4 modulation, the transceiver supports 400GAUI-8 / CEI-56G-VSR-PAM4 electrical interfaces, enabling high-bandwidth, low-latency short-reach connectivity.
400G QSFP-DD SR8 transceiver supports 200G QSFP56 switch/NIC interconnection solution and also supports interconnection with 2x200G QSFP112 NICs, effectively enabling a smooth network upgrade from 200G to 400G. With this flexibility, it delivers ultra-high-density 400 Gigabit Ethernet connectivity for data centers, high-performance computing (HPC) networks, enterprise core and aggregation layers, and service provider infrastructures.
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.
