Mellanox (NVIDIA Mellanox) MMA4Z00-NS Data Center Optical Module | Product Launch & Key Features

As data center traffic continues to surge toward 800G and beyond, network architects and IT managers face a growing challenge: how to scale bandwidth without compromising port density, power efficiency, or interoperability. NVIDIA has now addressed this with the official introduction of the Mellanox (NVIDIA Mellanox) MMA4Z00-NS, a new-generation data center optical module designed for high-performance InfiniBand and Ethernet fabrics.

Why the MMA4Z00-NS Matters

Traditional 400G solutions often require complex breakout cabling or sacrifice backward compatibility when transitioning to 800G. The NVIDIA Mellanox MMA4Z00-NS eliminates these trade-offs by delivering dual‑mode operation: it functions as a native 800G OSFP SR8 transceiver or as a 2x400G breakout module. This flexibility allows data center operators to protect existing investments while building a clear upgrade path toward higher radix switches and AI clusters.

Built for dense spine-leaf and supercomputing environments, the MMA4Z00-NS 800G OSFP SR8 transceiver supports multimode fiber (MMF) with eight 100G PAM4 lanes. It maintains full compatibility with NVIDIA Quantum-2 and Spectrum-4 switch platforms, ensuring that teams can deploy the module without re‑architecting their current cabling infrastructure.

Key Technical Capabilities

• 800G OSFP SR8 native mode: Delivers aggregate 800Gb/s over eight parallel multimode fiber pairs, ideal for top-of-rack and intra‑cluster connections.
• 2x400G breakout (InfiniBand/Ethernet): The MMA4Z00-NS 2x400G InfiniBand/Ethernet mode allows a single module to feed two separate 400G ports, reducing transceiver count and simplifying cable management.
• Low latency & power efficiency: Optimized PAM4 DSP and passive copper-like thermal profile help maintain switch airflow and energy budgets.
• Management & telemetry: Full support for CMIS 5.0 and NVIDIA’s in‑band monitoring, providing real-time optical diagnostics and link health metrics.

According to preliminary MMA4Z00-NS datasheet and MMA4Z00-NS specifications, the module operates over OM4/OM5 fiber up to 50 meters (800G) or 100 meters (2x400G). It uses a standard OSFP form factor with integrated pull-tab latch, making it hot-swappable across all NVIDIA Mellanox 800G-enabled switches and adapters.

Deployment Scenarios and Availability

For network architects planning AI fabric upgrades or large-scale cloud expansion, the MMA4Z00-NS 800G OSFP SR8 transceiver solution eliminates the need for separate 400G and 800G inventory. In InfiniBand environments, the MMA4Z00-NS 2x400G InfiniBand/Ethernet capability is particularly valuable for connecting dual‑port GPUs or storage nodes without wasting switch port capacity. Early access programs are now open, with general availability expected in the current quarter.

Pricing and volume inquiries are directed to authorized NVIDIA Mellanox distributors. For teams seeking MMA4Z00-NS price and MMA4Z00-NS for sale options, it is advisable to contact regional partners for batch quotes. Compatibility validation extends beyond NVIDIA switches; the module also operates in third-party 800G OSFP ports that follow QSFP-DD800/OSFP CMIS guidelines, though official MMA4Z00-NS compatible lists are maintained for assured performance.

Summary

The Mellanox (NVIDIA Mellanox) MMA4Z00-NS redefines 800G optical economics by combining SR8 and 2x400G breakout into a single OSFP footprint. For IT managers and architects who require a future-proof, easy-to-deploy transceiver that scales from today’s 400G fabrics to tomorrow’s 800G backbones, the MMA4Z00-NS delivers a clear, no-compromise answer.
