NVIDIA/Mellanox Compatible 400G QSFP-DD LR8 PAM4 8LWDM Lanes MUX/DEMUX design Optical Transceiver Module ( Duplex LC 10km SMF with FEC DDM)
NADDOD NVIDIA/Mellanox QDD-400G-LR8 compatible optical transceiver module features duplex LC connectors and supports transmission distances of up to 10 km over single-mode fiber. It is fully compliant with IEEE 802.3bs and 400GAUI-8 / CEI-56G-VSR-PAM4 standards. This transceiver adopts PAM4 modulation, a QSFP-DD form factor, and an integrated DSP chip, delivering high-performance, reliable 400G optical connectivity.
Designed for high-bandwidth applications, the 400G QSFP-DD LR8 module is widely deployed in 400G telecom networks, data center interconnect (DCI), metro and long-haul networks, as well as high-performance computing (HPC) environments. It is also well suited for data center Ethernet switching and routing, storage area networks (SANs), and emerging applications such as 5G mobile networks, high-speed video streaming, AI, and cloud computing.
400G Data Center Interconnect (DCI) solutions provide 400G port speeds and effectively minimize the cost of interconnecting data centers. NADDOD's optical connectivity products enable long-distance metropolitan area network expansions and facilitate fast migration of massive data between data centers. This solution eliminates bandwidth bottlenecks, significantly enhances bandwidth, and improves the utilization rate between data centers.
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.
