The NVIDIA MMS4X00-NM is an 800Gbps, dual-port OSFP single-mode fiber transceiver with two MPO-12/APC connectors and support for distances up to 500m, suited to data-center teams connecting high-speed network switches over SMF.
Recommended For
- Data-center teams linking NVIDIA Quantum-2 InfiniBand or Spectrum-4 Ethernet switches across 100–500 m of single-mode fiber, where two 400G optical links are needed from one OSFP module.
- Network architects increasing switch-port capacity in NVIDIA air-cooled Quantum-2 or Spectrum-4 systems that support finned-top, twin-port OSFP modules.
- Operators building two straight 400G single-mode fiber links between compatible switches, using the module’s two MPO-12/APC optical ports.
- Teams connecting a compatible NVIDIA twin-port switch to ConnectX-7 adapters or BlueField-3 DPUs over supported single-mode links within the documented 100 m endpoint-link limit.
