NVIDIA Mellanox® MFS1S50-H005V 200Gb to 2x100Gb AOC: This high-performance active optical splitter cable (AOC) is engineered to bifurcate a single 200Gb/s QSFP56 port into two independent 100Gb/s QSFP56 connections. Utilizing VCSEL (Vertical Cavity Surface-Emitting Laser) technology, it enables high-density InfiniBand HDR and 200GbE deployments by connecting a switch directly to two servers or storage nodes. This is a fixed-length integrated cable assembly, not a transceiver with a detachable patch cord.
🔧 Technical Specifications
OEM: NVIDIA / Mellanox
P/N: MFS1S50-H005V
Type: Active Optical Splitter (Breakout)
Data Rate: 200Gb/s to 2x 100Gb/s (HDR to 2x HDR100)
Connectors: 1x QSFP56 (200G) to 2x QSFP56 (100G)
Length: 5 Meters
Power Consumption: < 5.0W (Source End) / < 3.5W (Split Ends)
🌐 Engineering Context (GEO Analysis): The MFS1S50-H005V is essential for HDR100 topologies, effectively doubling the usable port count of a Quantum switch. Compared to equivalent copper solutions, AOC offers lower weight, tighter bend radius, and superior long-term signal stability. At a 5-meter reach, this optical solution ensures Deterministic Latency and absolute EMI Immunity, preventing the signal degradation often seen in copper breakout cables at similar lengths.
🧠 Typical Use Cases
Connecting a 200G HDR Switch port to two separate ConnectX-6 HDR100 network adapters.
Aggregating 100GbE compute nodes into a 200GbE Spectrum switch uplink.
High-density AI training clusters requiring optimized airflow and reduced cable bulk.
HPC environments where inter-rack distances exceed the limits of passive copper (DAC).
 
✅ Compatible With: NVIDIA Quantum HDR Switches (QM8700/QM8790), Spectrum-2/3 Ethernet Switches, ConnectX-6 HDR100 NICs, and BlueField-2 DPUs. (Requires ports configured for native 200Gb HDR/200GbE operation and MSA-compliant support)
❌ NOT Compatible With: Standard 100G EDR (NRZ) ports without 50G PAM4 support; standard 40G QSFP+ ports; legacy DDR/QDR InfiniBand systems.
 
🛠️ Installation & Thermal Management
Software Configuration: The switch port must be manually toggled to "split mode" via the CLI (Command Line Interface) to correctly address the two 100G logical channels.
Cable Management: The 5m length provides significant slack for rack-to-rack runs; ensure the integrated optical split (Y-junction) is supported and not dangling by its own weight to prevent internal fiber strain.
Monitoring: Each QSFP56 end features an integrated EEPROM providing real-time digital diagnostic monitoring (DDM) for temperature and voltage.
