NVIDIA MMS4X00-NS 800Gb/s Twin-port OSFP 2xDR4 Optical Transceiver

NVIDIA MMS4X00-NS is an industrial-grade 800Gb/s Twin-port OSFP 2xDR4 single-mode parallel optical transceiver engineered specifically for high-density InfiniBand NDR and high-speed 400G/800G Ethernet infrastructures. It is primarily deployed on the switch side (e.g., Quantum-2 or Spectrum-4 switches) to interconnect infrastructure nodes across shorter data center lengths.
