Transceiver Module : NVIDIA MMS4X00-NS Twin-port Transceiver, 800Gbps, 2xNDR / Ethernet, OSFP Form Factor, Dual MPO-12/APC Connectors, 1310nm Single-Mode Fiber (SMF), 2xDR4 Optics, Up to 100m Reach, Finned Top Shell
The NVIDIA MMS4X00-NS is an original 800Gb/s (2x400Gb/s) Twin-port OSFP optical transceiver designed for high-density, low-latency AI supercomputing and hyperscale enterprise networks. Supporting both NVIDIA NDR InfiniBand and 400GbE Ethernet protocols, this parallel single-mode transceiver features two independent 4-channel 100G-PAM4 engines delivering aggregate throughputs of up to 800Gbps over single-mode fiber (SMF) up to 100 meters.
Engineered with a Finned-Top OSFP shell, the MMS4X00-NS provides thermal management for air-cooled switch environments such as NVIDIA Quantum-2 (QM9700/QM9790) NDR InfiniBand switches and Spectrum-4 Ethernet platforms. Utilizing dual MPO-12/APC optical connectors, it supports flexible interconnect topologies including direct 800G switch-to-switch links, dual 400G straight connections to ConnectX-7 / BlueField-3 DPUs, or 1:2 breakout configurations connecting up to four 200G NDR200 endpoints.
Key Features
- 800Gbps Twin-Port Architecture: Operates as two independent 400Gb/s (2x400G) optical ports within a single OSFP form factor using 8-channel 100G-PAM4 modulation.
- Dual MPO-12/APC Optical Interface: Equipped with two 4-channel MPO-12/APC optical connectors for precise single-mode alignment and low return loss.
- Finned-Top Thermal Design: Specialized finned OSFP shell optimized for enhanced airflow and heat dissipation in air-cooled Quantum-2 and Spectrum-4 switches.
- Versatile Network Topology: Supports straight 400G connections (MFP7E30 crossover cables) up to 100m or 1:2 splitter cables (MFP7E40) for 200G NDR200 links up to 50m.
- Energy Efficient & Hot-Pluggable: Low power consumption of ≤17W at full operation with a 1.5W low-power sleep mode capability.
- Compliance & Reliability: Class 1 laser safe, RoHS compliant, CMIS 4.0 compliant, and fully validated for end-to-end NVIDIA InfiniBand / Ethernet fabrics.
