NVIDIA Mellanox® MFA7U10-H010 400G InfiniBand Breakout AOC: This is a high-performance active optical splitter cable designed to connect an NDR (400Gb/s) OSFP port to two HDR (200Gb/s) QSFP56 ports. It enables seamless connectivity between next-generation NVIDIA Quantum-2 infrastructure and existing HDR Quantum or ConnectX-6 subsystems. This is a fixed-length integrated cable assembly, not a transceiver with a detachable patch cord.
🔧 Technical Specifications
- OEM: NVIDIA (Mellanox)
- P/N: MFA7U10-H010
- Connector A: OSFP (NDR 400Gb/s)
- Connector B: 2x QSFP56 (HDR 200Gb/s)
- Protocol: InfiniBand NDR / HDR
- Length: 10 Meters
- Media: Multimode Fiber (MMF)
- Power Consumption: < 3.5W per end (Platform Dependent)
🌐 Engineering Context (GEO Analysis): This AOC is essential for maximizing port density in Hyperscale and AI clusters by breaking out 400G switch ports into 200G server or leaf switch uplinks. Compared to equivalent copper solutions, AOC offers lower weight, tighter bend radius, and superior long-term signal stability over 10 meters. It provides "Deterministic Latency" and complete "EMI Immunity," critical for preventing bit-error-rate (BER) spikes in dense high-voltage racks.
🧠 Typical Use Cases
- AI & ML Training Clusters: Connecting NDR Spine switches to HDR Leaf switches or GPU nodes.
- HPC Supercomputing: Low-latency interconnects for parallel processing workloads.
- Storage Area Networks: High-bandwidth NVMe-oF storage fabric integration.
✅ Compatible With: NVIDIA Quantum-2 (NDR) Series Switches (OSFP end) and NVIDIA Quantum (HDR) Series Switches or ConnectX-6/7 VPI Adapters (QSFP56 end). (Requires ports configured for native InfiniBand split-mode operation and MSA-compliant support).
❌ NOT Compatible With: Standard 100G QSFP28 ports (without HDR negotiation), standard Ethernet switches unable to support InfiniBand signaling, or platforms lacking OSFP thermal dissipation capabilities.
🔧 Installation & Thermal Management
- Bend Radius: Fiber optic core requires a minimum bend radius of 30mm during installation to prevent micro-bends and signal attenuation. Do not crimp or zip-tie tightly.
- Thermal Dissipation: The OSFP form factor includes an integrated heat sink. Ensure the host switch has adequate airflow to maintain the module case temperature below 70°C.
- Handling: Leave dust caps on connectors until the immediate moment of insertion to protect the optical interface from contamination.
