NVIDIA Mellanox® MFS1S50-H003V 200Gb to 2x100Gb AOC: This active optical splitter cable (AOC) is a high-performance interconnect designed to bridge a single 200Gb/s QSFP56 port into two discrete 100Gb/s QSFP56 endpoints. Engineered for InfiniBand HDR and 200GbE systems, it enables data centers to double their port density by connecting high-bandwidth switches to multiple 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-H003V
Type: Active Optical Splitter (Breakout)
Data Rate: 200Gb/s to 2x 100Gb/s (HDR100)
Connectors: 1x QSFP56 (200G) to 2x QSFP56 (100G)
Length: 3 Meters
Power Consumption: < 5.0W (Source) / < 3.5W (Ends)
🌐 Engineering Context: The MFS1S50-H003V is the architectural solution for "HDR100" deployments. Compared to equivalent copper solutions, AOC offers lower weight, tighter bend radius, and superior long-term signal stability. By utilizing this optical splitter, engineers achieve Deterministic Latency and EMI Immunity over a 3m span, which is vital for maintaining signal integrity in high-density AI clusters where copper crosstalk could compromise performance.
🧠 Typical Use Cases
Connecting one NVIDIA Quantum HDR Switch port to two ConnectX-6 HDR100 Adapters.
Maximizing port density in Top-of-Rack (ToR) switching architectures.
Aggregating dual 100GbE links into a single 200GbE uplink in Spectrum-2/3 fabrics.
High-frequency trading environments requiring stable, low-latency optical paths.
 
✅ Compatible With: NVIDIA Quantum HDR Switches (QM8700/QM8790), 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 QSFP28 100G ports (unless 50G PAM4 support is specified); legacy InfiniBand EDR/FDR systems; 4-way 4x50G to 4x50G splitting (this is a 2-way splitter only).
 
🛠️ Installation & Thermal Management
Logical Mapping: Ensure the switch OS (MLNX-OS / Cumulus) is configured to "split" the 200G port into 2x100G logical interfaces before installation.
Fiber Integrity: Avoid sharp bends at the "Y-junction" (splitter point); the internal MMF fibers are sensitive to mechanical stress at the transition.
Power Management: Each connector contains an EEPROM for SFF-8636 compliant monitoring; ensure firmware is updated to recognize HDR100 AOC power profiles.
