NVIDIA Mellanox® MFS1S50-H010V 200Gb to 2x100Gb AOC: This high-performance active optical splitter cable (AOC) is designed to split a single 200Gb/s QSFP56 port into two 100Gb/s (HDR100) endpoints. Utilizing VCSEL-based technology over multi-mode fiber, it allows for high-density interconnects at distances up to 10 meters, far exceeding the reach of passive copper. This is a fixed-length integrated cable assembly, not a transceiver with a detachable patch cord.
🔧 Technical Specifications
OEM: NVIDIA / Mellanox
P/N: MFS1S50-H010V
Type: Active Optical Splitter (Breakout)
Data Rate: 200Gb/s to 2x 100Gb/s (HDR to 2x HDR100)
Connector Type: QSFP56 to 2x QSFP56
Length: 10 Meters
Power Consumption: < 5.0W (Source End) / < 3.5W (Split Ends)
🌐 Engineering Context: The MFS1S50-H010V is the architectural solution for "HDR100" deployments where switches and servers are located in different racks. Compared to equivalent copper solutions, AOC offers lower weight, tighter bend radius, and superior long-term signal stability. The 10m length enables "Middle-of-Row" (MoR) switching topologies while maintaining Deterministic Latency and EMI Immunity, essential for preventing bit errors in high-speed 50G PAM4 signaling.
🧠 Typical Use Cases
Connecting a 200G HDR Switch port to two separate ConnectX-6 HDR100 adapters across different racks.
Aggregating 100GbE compute nodes into a 200GbE Spectrum switch uplink at distance.
High-density AI training clusters requiring optimized airflow and reduced cable congestion.
Inter-rack connectivity where 10m reach is required for complex cable routing.
 
✅ Compatible With: NVIDIA Quantum HDR Switches (QM8700/QM8790), Spectrum-2/3 Ethernet Switches, ConnectX-6 HDR100 NICs, and BlueField-2/3 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; legacy 40G QSFP+ ports; standard 10G/25G networking hardware.
 
🛠️ Installation & Thermal Management
Split-Port Configuration: The source switch port must be logically configured to "Split Mode" (2x100G) via the network operating system (MLNX-OS or Cumulus) to enable traffic across both legs.
Fiber Management: At 10 meters, proper vertical cable management is vital. Ensure the "Y-junction" is not bearing the weight of the 10m cable run to avoid internal fiber fractures.
Bend Radius: Maintain a minimum 60mm static bend radius. Avoid tight zip-ties which can cause "micro-bends" and intermittent link flapping at 50G PAM4 speeds.
