NVIDIA OSFP Module

Introducing the NVIDIA OSFP Module — a high-performance, hot-swappable 400G optical transceiver designed to meet the demands of modern data centers and cloud-scale networks. Featuring the Mma4z00-ns-flt SKU, this OSFP module enables dense, scalable 400G Ethernet connectivity across NVIDIA networking platforms, including switches, routers, and NICs that support OSFP form factors. Built for hyperscale environments, the module combines multi-lane performance with advanced diagnostics, energy efficiency, and proven reliability to reduce total cost of ownership while delivering ultra-low latency and high throughput for spine-leaf fabrics, AI workloads, and storage networks. Whether you’re upgrading an existing infrastructure or architecting a new fabric, the NVIDIA OSFP Module is engineered to deliver consistent, predictable performance in demanding 24/7 operations.

• OSFP form factor for maximum density — The Open Small Form-factor Pluggable design allows data centers to pack more 400G ports into compact hardware, improving port density in high-performance switches and servers and enabling scalable growth without hardware sprawling.
• 400G performance through four 100G lanes — Designed to deliver aggregated bandwidth of up to 400 Gbps by steering four parallel 100G lanes, this transceiver is ideal for modern fabric topologies that require high-throughput interconnects with low latency and minimal switch-to-switch congestion.
• Hot-swappable and enterprise-ready reliability — Built to support live replacement in compatible platforms, the module minimizes downtime and maintenance windows, allowing operators to swap, reseat, or upgrade without a complete maintenance outage when the host supports hot-swapping.
• Digital diagnostics and health monitoring — Equipped with digital diagnostics monitoring (DDM) capabilities and real-time signaling health checks, providing visibility into optical power, transceiver temperature, bias currents, and other metrics to prevent unexpected failures and optimize performance.
• Energy-efficient design for cooler operation — Optimized power management and thermal characteristics reduce cooling requirements in dense deployments, helping data centers lower total energy consumption while preserving peak optical performance.

How to install NVIDIA OSFP Module

• Prepare your equipment and workspace. Have appropriate ESD precautions in place and ensure you have a clean, lint-free environment for handling optical components.
• Check your platform’s specification for hot-swapping capability. Many NVIDIA OSFP-enabled devices support hot-swappable modules, but always follow vendor guidelines to prevent damage or voided warranties.
• Power-down the host or confirm hot-swap policy is active if your platform supports live replacement. If hot-swapping is supported, verify that there are no critical ongoing tasks on the interface to avoid traffic disruption.
• Identify the correct OSFP slot intended for the NVIDIA module. Align the module with the slot, ensuring that the connector edge and guides engage properly.
• Gently insert the module until it seats with a secure click. Do not force the module, and avoid tilting or bending the connector.
• Connect the fiber optic cables or copper DAC/optical cables to the module’s connectors, taking care to keep connectors clean and free of debris. Use proper ferrules and cleaning procedures as recommended by your network administrator.
• Secure cables to prevent strain on the module and verify that cabling is routed away from fans and hot areas to maintain optimal cooling. Power on the device if required by your platform and observe the status indicators.
• Access the device management interface to confirm link establishment. Use the management software to verify that the transceiver has recognized the module, and review Digital Diagnostics Monitoring (DDM) data for optical power, temperature, and other health metrics.
• Run a basic connectivity test, such as a throughput or loopback test, to ensure the link is stable and performing within expected ranges before placing the system into production.
