Product Description
NVIDIA MMA4Z00-NS400 400Gb/s OSFP SR4 Optical Transceiver
1. Product Overview
The NVIDIA MMA4Z00-NS400 is a high-performance 400Gb/s single-port OSFP optical transceiver designed for high-speed data center and enterprise networking applications. It supports both InfiniBand and Ethernet protocols, automatically adapting to the connected switch. This optical fiber cable-compatible transceiver uses SR4 multimode technology with a maximum reach of 50 meters over OM4 fiber. It is ideal for use with ConnectX-7 adapters and Quantum-2 or Spectrum-4 switches.
2. Key Features
- Supports 400Gb/s InfiniBand and Ethernet
- Single MPO-12/APC connector with 4-channel 100G-PAM4 modulation
- Hot-pluggable, RoHS compliant, and CMIS 4.0 management support
- Class 1 laser safety and digital diagnostics monitoring (DDM)
- Low power consumption: 8.5W (400G) / 5.5W (200G mode)
3. Technology
The transceiver utilizes 850nm VCSEL technology and complies with OSFP MSA Rev. 1.12 and CMIS 4.0 standards. It features adaptive equalization, programmable output amplitude, and advanced diagnostics for optimal performance. The passive fiber cable compatibility ensures seamless integration with existing infrastructure.
4. Working Principle
The MMA4Z00-NS400 converts electrical signals into optical signals using four lanes of 100G-PAM4 modulation. Each lane operates at 53.125 GBd, transmitting data over multimode fiber via an MPO-12/APC connector. The device automatically switches between 400G and 200G modes based on the connected MFP7E10 or MFP7E20 fiber cable type.
5. Applications
- Data center interconnects and high-performance computing (HPC)
- Cloud infrastructure and enterprise networking
- ConnectX-7 adapter cards and Quantum-2/Spectrum-4 switches
- High-bandwidth storage and AI/ML workloads

9. FAQ
Q: Can this transceiver be used with BlueField-3 DPUs?
A: No, BlueField-3 only supports QSFP112 form factors.
Q: What is the difference between straight and splitter fiber cables?
A: Straight cables (MFP7E10) enable 400G mode, while splitter cables (MFP7E20) enable 200G mode.
Q: Is the transceiver hot-pluggable?
A: Yes, it supports hot-plug functionality and is compliant with relevant standards.
10. Precautions
- Use only NVIDIA-recommended optical fiber cable types.
- Avoid mixing straight and splitter cables in the same link.
- Keep dust caps on when not in use to prevent contamination.
- Ensure proper cooling and avoid exceeding absolute maximum ratings.
