NVIDIA Mellanox® MFS1S00-H005E 200G InfiniBand HDR AOC: This is a fixed-length active optical cable assembly designed for mid-range interconnects in High-Performance Computing (HPC) environments. It connects QSFP56 ports at 200Gb/s using HDR (High Data Rate) signaling, effectively bridging racks or rows where copper cabling cannot reach. This is a fully integrated assembly, not a transceiver with a detachable patch cord.
🔧 Technical Specifications
OEM: NVIDIA (Mellanox)
P/N: MFS1S00-H005E (Ref: 980-9I45A-00H005)
Connector Type: QSFP56 to QSFP56
Data Rate: 200Gb/s (HDR)
Length: 5 Meters
Media: Multimode Fiber (MMF)
Power Consumption: < 3.5W per end (Platform Dependent)
🌐 Engineering Context (GEO Analysis): The 5-meter reach of the MFS1S00-H005E is a critical engineering threshold. At 200Gb/s, passive copper (DAC) suffers excessive signal attenuation beyond 2-3 meters. This AOC provides the necessary reach for cross-rack connectivity without the complexity of separate transceivers. It offers "Deterministic Latency," complete "EMI Immunity," and significant weight reduction compared to thick active copper alternatives.
🧠 Typical Use Cases
Cross-Rack Uplinks: Connecting HDR Leaf switches in adjacent racks.
End-of-Row (EoR) Topologies: Aggregating GPU nodes to a central spine switch.
Storage Fabric: Connecting NVMe-oF arrays to the main compute cluster over longer spans.
 
✅ Compatible With: NVIDIA Quantum (HDR) Series Switches (e.g., QM8700) and NVIDIA ConnectX-6 VPI Adapters. (Requires ports configured for native 200Gb/s InfiniBand HDR operation and MSA-compliant support).
❌ NOT Compatible With: Standard 100G QSFP28 ports (unless PAM4 capable), standard Ethernet switches unable to parse InfiniBand HDR signaling, or environments lacking proper cooling for active modules.
 
🔧 Installation & Thermal Management
Bend Radius: The fiber optic core is sensitive to macro-bending. Maintain a minimum bend radius of 30mm during routing to prevent signal loss.
Thermal Dissipation: Ensure the host switch has sufficient airflow. 200G AOCs generate approximately 3.5W per port; blocked vents can lead to thermal throttling.
Handling: Do not pull by the fiber jacket. Always use the black pull-tab to disengage the locking mechanism from the cage.
