LENOVO Mellanox® 01PG7411 200Gb to 2x100Gb AOC: This high-performance active optical splitter cable (AOC) is a Lenovo-certified Field Replaceable Unit (FRU) designed to bifurcate a single 200Gb/s QSFP56 port into two discrete 100Gb/s (HDR100) connections. Optimized for Lenovo ThinkSystem environments and NVIDIA Quantum HDR switches, it provides an efficient, long-reach solution for maximizing port density in high-performance computing (HPC) clusters. This is a fixed-length integrated cable assembly, not a transceiver with a detachable patch cord.
🔧 Technical Specifications
OEM: Lenovo (Mellanox Original)
P/N (FRU): 01PG741
Cross-Reference: MFS1S50-H005V / NVIDIA 980-9I969-00H005
Type: Active Optical Splitter (Breakout)
Data Rate: 200Gb/s to 2x 100Gb/s (HDR to 2x HDR100)
Length: 5 Meters
Power Consumption: < 5.0W (Source End) / < 3.5W (Split Ends)
🌐 Engineering Context: The Lenovo 01PG741 is the preferred interconnect for HDR100 topologies where switch port conservation is vital. Compared to equivalent copper solutions, AOC offers lower weight, tighter bend radius, and superior long-term signal stability. The 5-meter optical reach ensures Deterministic Latency and total EMI Immunity, making it indispensable for AI/ML training clusters where copper cables would suffer from excessive signal attenuation and electromagnetic interference.
🧠 Typical Use Cases
Connecting a single port on a Lenovo ThinkSystem NVIDIA Quantum HDR Switch to two separate HDR100 adapters.
Expanding server connectivity in Lenovo ThinkSystem SD530/SD650 high-density nodes.
Data center interconnects requiring 5-meter spans where passive DAC limits are exceeded.
Aggregating dual 100G links into a single 200G uplink in Lenovo/Mellanox-based fabrics.
 
✅ Compatible With: Lenovo ThinkSystem HDR Switches, ConnectX-6 HDR100 Network Adapters, and NVIDIA Quantum QM8700/QM8790 switches. (Requires ports configured for native 200Gb HDR operation and MSA-compliant support)
❌ NOT Compatible With: Standard 100G EDR (NRZ-based) ports without 50G PAM4 support; legacy 40G/56G InfiniBand hardware; non-HDR compliant Ethernet-only switches.
 
🛠️ Installation & Thermal Management
FRU Validation: As a Lenovo FRU (01PG741), this cable is fully recognized by Lenovo XClarity management software, allowing for native monitoring of optical levels and thermal health.
Bend Radius: Maintain a minimum static bend radius of 60mm. The 5m length requires proper cable management to prevent internal fiber strain, particularly at the Y-splitter junction.
Port Configuration: Ensure the switch port is set to "split" mode via the CLI to enable the 2x100G logical interface mapping.
