NVIDIA MMA4Z00-NS400 400Gb/s OSFP SR4 Multimode Transceiver
Single-Port 400G NDR InfiniBand/Ethernet Optical Module for ConnectX-7, MPO-12/APC, 50m Reach on OM4 Fiber
NVIDIA MMA4Z00-NS400
The NVIDIA MMA4Z00-NS400 is a 400Gb/s single-port OSFP SR4 multimode transceiver designed for NVIDIA ConnectX-7 adapters and Quantum-2 / Spectrum-4 switches. It supports both InfiniBand and Ethernet protocols with automatic protocol detection. Utilizing 4 channels of 100G PAM4 modulation, it delivers up to 50 meters reach over OM4 multimode fiber via a single MPO-12/APC connector. The flat-top design integrates with the riding heatsink on ConnectX-7 cages for optimal thermal performance.
Product Overview
The MMA4Z00-NS400 is a key component in NVIDIA's end-to-end 400G InfiniBand and Ethernet ecosystems. It is specifically engineered for use with ConnectX-7 OSFP-based host channel adapters (HCAs) and connects to twin-port OSFP transceivers in NVIDIA Quantum-2 or Spectrum-4 switches. The module features 4 independent transmit and receive channels using 850nm VCSEL technology. When paired with a 1:2 splitter fiber cable (MFP7E20 series), only two channels are activated, automatically reducing the speed to 200Gb/s (NDR200) and lowering power consumption to 5.5W. The transceiver is CMIS 4.0 compliant and supports advanced digital diagnostics monitoring (DDM).
Key Features
- Dual-Protocol Support: Seamlessly operates in both InfiniBand (NDR) and Ethernet (400GbE) environments with automatic protocol detection.
- High-Speed Optics: 4 channels of 100G PAM4 modulation with 850nm VCSEL arrays.
- Extended Reach: 50 meters over OM4 multimode fiber, 30 meters over OM3.
- Intelligent Power Scaling: Automatically reduces power from 8.5W to 5.5W when operating in 200G mode (2-channel mode).
- Flat-Top OSFP Design: Optimized for thermal management with the riding heatsink on ConnectX-7 adapter cages.
- Angled Polish Connector: MPO-12/APC (green shell) minimizes back reflection; not compatible with UPC (aqua) connectors.
- Comprehensive Diagnostics: Supports Tx/Rx power monitoring, bias current, voltage, and temperature via DDM.
- Regulatory Compliance: Class 1 laser safety, RoHS compliant, OSFP MSA and CMIS 4.0 compliant.
Optical & Electrical Technology
The MMA4Z00-NS400 leverages 100G per lane PAM4 modulation technology. The electrical host interface consists of 8 differential pairs (4 Tx, 4 Rx) operating at 53.125 Gbaud. The optical engine uses 850nm VCSELs with integrated driver and TIA arrays. The module includes adaptive Tx input equalization, programmable Rx output amplitude, and pre-/post-cursor tuning for signal integrity optimization. Built-in PRBS generator and checker enable in-system link validation without external test equipment.
Typical Deployments & Use Cases
- Switch-to-HCA 400G Links: Connecting a Quantum-2 or Spectrum-4 switch (using twin-port transceivers) to a ConnectX-7 OSFP adapter via straight MFP7E10 fiber cables.
- 200G Fan-Out Configuration: Using MFP7E20 1:2 splitter cables to connect one twin-port switch transceiver to four ConnectX-7 adapters operating at 200Gb/s each.
- Switch-to-Switch Uplinks: Direct attachment to twin-port transceivers in switches for 400G or 800G aggregation.
- High-Density AI Clusters: Enabling low-latency, high-bandwidth connectivity in GPU-accelerated environments with BlueField-3 DPUs (via QSFP112 adapters).
Note: This OSFP module is not compatible with BlueField-3 DPUs, which require QSFP112 form factor.
Compatibility
- Adapters: NVIDIA ConnectX-7 OSFP-based Host Channel Adapters.
- Switches: NVIDIA Quantum-2 InfiniBand switches (with twin-port OSFP), NVIDIA Spectrum-4 Ethernet switches.
- Fiber Cables: NVIDIA MFP7E10 series (straight, 4-channel MPO/APC to MPO/APC) and MFP7E20 series (1:2 splitter, 4-channel to dual 2-channel MPO/APC).
- Protocols: InfiniBand NDR (400Gb/s) and NDR200 (200Gb/s); Ethernet 400GbE and 200GbE.

Frequently Asked Questions
Q: Can the MMA4Z00-NS400 be used in a BlueField-3 DPU?
A: No. BlueField-3 adapters only accept QSFP112 form factor modules. This OSFP module is designed for ConnectX-7 OSFP adapters and switches.
Q: What is the difference between the green and aqua MPO connectors?
A: Green indicates an Angled Polished Connector (APC) used in this transceiver. Aqua indicates Ultra-polished Connector (UPC). They are not compatible due to different polish angles.
Q: How does the transceiver automatically switch to 200G mode?
A: When an MFP7E20 splitter cable is inserted, only two of the four fiber channels are physically present. The transceiver detects this and activates only two lanes, reducing speed and power.
Q: What is the typical power consumption at 400G?
A: Typical power is 8.0W, with a maximum of 8.5W. In 200G mode, typical power drops to 5.5W.
Handling & Installation Precautions
- Always use dust caps on optical ports when not connected. Save the caps for future use.
- Clean both the transceiver receptacle and the fiber connector before insertion. Contamination is a leading cause of link failure.
- Avoid exposure to static discharge. Follow ESD-safe handling procedures.
- Do not mix UPC and APC connectors; verify connector type (green shell = APC).
- Ensure the host device (adapter/switch) supports the OSFP form factor and the required firmware version.
