The SFPPlaza NVIDIA/Mellanox MMS1X00-NS400 Compatible 400G DR4 QSFP112 Optical Transceiver Module is designed for high-performance 400Gb/s InfiniBand NDR and Ethernet data center interconnects. Operating at a 1310nm wavelength, it uses four 100G PAM4 optical lanes to deliver an aggregate bandwidth of 400Gb/s over single-mode fiber (SMF) with a transmission distance of up to 500 meters.
Featuring a QSFP112 form factor and a single MPO-12/APC optical connector, this transceiver provides a high-density, pluggable connectivity solution for next-generation data center networks, high-performance computing (HPC), and AI infrastructure. Its flat-top housing is designed for compatible QSFP112 adapter cages, including supported NVIDIA ConnectX-7 and BlueField-3 platforms.
The 400G DR4 architecture enables high-speed parallel optical transmission over single-mode fiber. With four independent 100G PAM4 lanes, the module supports 400Gb/s connectivity through a single MPO-12/APC interface. Digital Diagnostic Monitoring (DOM) provides access to key operating parameters, helping network administrators monitor module status and maintain link performance.
For switch-to-adapter connectivity, the MMS1X00-NS400 QSFP112 transceiver can be deployed on supported ConnectX-7 or BlueField-3 adapter ports and connected to compatible OSFP-800G-2xDR4 modules on NVIDIA Quantum-2 switches, including QM9700 and QM9790 platforms. A compatible MPO-12/APC single-mode fiber link is required, and the host port configuration must support the intended connection.
Built for demanding InfiniBand NDR and high-speed Ethernet environments, the MMS1X00-NS400 offers a practical optical connectivity solution for AI clusters, HPC systems, cloud data centers, and large-scale data center networks. Each module is tested for compatibility and optical performance to help ensure reliable operation on supported platforms.
