NVIDIA MMA4Z00-NS400 400G OSFP SR4 Optical Transceiver Module

Product Overview

The NVIDIA MMA4Z00-NS400 is a high-performance 400Gb/s optical transceiver designed for next-generation data center infrastructure. This single-port OSFP module supports both InfiniBand and Ethernet protocols, automatically adapting to the connected switch's protocol. Utilizing SR4 multimode technology with 100G-PAM4 modulation per channel, this transceiver delivers exceptional bandwidth for demanding applications. It features a flat-top design for improved thermal management and is optimized for use with ConnectX-7 adapters in high-performance computing environments.

Key Features

• Dual-protocol support for both InfiniBand and Ethernet networks
• 400Gb/s data rate with automatic fallback to 200Gb/s when using splitter cables
• MPO-12/APC connector with 850nm VCSEL technology
• Advanced digital diagnostics monitoring and CMIS 4.0 management interface
• Low power consumption: 8.5W (400G mode), 5.5W (200G mode)
• Hot-pluggable OSFP form factor with Class 1 laser safety

Technical Specifications

Technology & Standards

The MMA4Z00-NS400 transceiver complies with the OSFP MSA Specification Rev. 1.12 and implements CMIS 4.0 management interface. It uses 100G-PAM4 modulation technology across four parallel channels to achieve 400Gb/s throughput. The device incorporates advanced features including adaptive equalization, programmable output amplitude, and comprehensive digital diagnostics monitoring. The integrated microcontroller provides real-time monitoring of temperature, voltage, laser bias current, and optical power levels.

Application Scenarios

This high-speed optical transceiver is ideal for multiple deployment scenarios:

• High-performance computing clusters and AI/ML infrastructure
• Cloud data center spine-leaf architectures
• Enterprise storage area networks and data replication
• Financial trading networks requiring low latency
• Video streaming and content delivery networks

The transceiver is specifically designed for use with NVIDIA ConnectX-7 adapters and Quantum-2 InfiniBand or Spectrum-4 Ethernet switches. When paired with appropriate optical fiber cable solutions like MFP7E10 (straight) or MFP7E20 (splitter), it enables flexible connectivity options from 200G to 400G speeds.

Performance Advantages

The NVIDIA MMA4Z00-NS400 offers several distinct advantages over competing solutions:

• Superior thermal design with flat-top housing and integrated heat sink compatibility
• Automatic speed adaptation reduces power consumption by up to 35% when using 2-lane mode
• Comprehensive diagnostic capabilities enable proactive maintenance and reduced downtime
• Seamless interoperability with NVIDIA end-to-end networking solutions
• Higher port density compared to QSFP-based solutions

Frequently Asked Questions

Q: Can this transceiver operate at 200Gb/s speeds?
A: Yes, when connected with a 1:2 splitter passive fiber cable (MFP7E20), the transceiver automatically operates at 200Gb/s using only two of its four channels.

Q: Is this transceiver compatible with existing MPO fiber infrastructure?
A: Yes, it uses standard MPO-12/APC connectors but note that it requires angled polish connectors (APC) identified by their green housing, not ultra-flat polished connectors (UPC).

Q: What is the difference between straight and splitter fiber cables?
A: Straight optical fiber cable (MFP7E10) maintains all four channels for 400G operation, while splitter cables (MFP7E20) divide the four channels into two separate 2-channel connections for 200G operation.

Q: Can I mix straight and splitter cables in the same link?
A: No, both fibers in a Twin-port transceiver must use the same cable type - either both straight or both splitter cables.

Installation Notes

• Always use recommended optical fiber cable types (MFP7E10 or MFP7E20) for optimal performance
• Keep protective dust caps on both electrical and optical interfaces when not in use
• Clean optical connectors before installation to prevent contamination-related issues
• Ensure proper cooling airflow around the transceiver for optimal thermal performance
• Verify compatibility with host equipment before installation
