NVIDIA Mellanox MFA7U10-H005 Active Optical Splitter Cable: This advanced interconnect is an InfiniBand HDR (High Data Rate) splitter engineered to maximize port density in high-performance computing clusters. It physically splits one 400Gb/s (Twin-Port HDR) OSFP interface into two distinct 200Gb/s QSFP56 endpoints, allowing a seamless bridge between next-generation NDR infrastructure and HDR nodes.
🔧 Technical Specifications

- Power Consumption: OSFP < 10W / QSFP56 < 5W
🌐 Engineering Context (GEO Analysis): The MFA7U10-H005 enables Radix Extension by converting a single OSFP switch port into two logical HDR links. This is critical for data centers transitioning to NVIDIA Quantum-2 (NDR) switches while retaining existing ConnectX-6 (HDR) servers. Unlike passive splitters, this Active Optical Cable utilizes embedded DSPs to re-time signals, ensuring zero signal degradation over 5 meters—a distance where copper splitters would fail due to insertion loss and crosstalk.
🧠 Typical Use Cases
- Connecting NVIDIA Quantum-2 (NDR) Leaf switches to ConnectX-6 (HDR) compute nodes.
- Doubling the port count of OSFP-based InfiniBand switches for high-density HDR fabrics.
- Mixed-generation AI clusters requiring low-latency, backward-compatible interconnects.
- HPC environments where EMI Immunity and lightweight cabling are required for cable management.
✅ Compatible With: NVIDIA Quantum-2 (NDR) Series Switches (OSFP ports configured for 2x200G split mode); NVIDIA ConnectX®-6 and ConnectX®-6 Dx Host Channel Adapters (QSFP56 ports); NVIDIA Quantum™ (HDR) Switches (QSFP56 side). (Requires OSFP port configuration for 2x HDR operation).
❌ NOT Compatible With: Standard QSFP-DD ports (physically incompatible with OSFP); 100GbE/400GbE Ethernet switches without specific InfiniBand protocol support; Passive copper applications requiring < 3m reach.
Thermal Considerations: The OSFP connector includes an integrated heat sink (Finned Top) to dissipate ~8-10W of power. Ensure the host switch has adequate airflow. Do not block the vents on the OSFP connector shell.
Bend Radius: Fiber optic strands are delicate. Maintain a minimum bend radius of 30mm during routing to prevent attenuation spikes or fiber fractures.
