LENOVO Mellanox® 01PG736 (MFS1S00-H020E) Active Optical Cable: This is a fixed-length integrated cable assembly, not a transceiver with a detachable patch cord. Engineered for large-scale enterprise data center deployments, this 20-meter Active Optical Cable (AOC) delivers robust 200Gb/s throughput using QSFP56 connectors. It leverages advanced VCSEL optical technology integrated directly into the connector shell, enabling high-bandwidth HDR connectivity over distances that far exceed the physical limitations of passive copper cabling.
🔧 Technical Specifications
OEM: Lenovo (Licensed from NVIDIA/Mellanox)
Lenovo P/N: 01PG736 (FRU)
NVIDIA/Mellanox Model: MFS1S00-H020E (Ref P/N: 980-9I45A-00H020)
Connector Type: QSFP56 to QSFP56
Data Rate: 200Gb/s HDR (4x 50G PAM4)
Length: 20 Meters
Power Consumption: < 3.5W per end (Platform Dependent)
🌐 Engineering Context: The 01PG736 is the "Row-Bridging" solution for Lenovo ThinkSystem infrastructures. At 20 meters, it allows for the interconnection of server racks in distinct zones or aisles. Compared to equivalent copper solutions (which fail beyond 3m at these speeds), this AOC offers significantly lower weight (reducing stress on the QSFP cage), enhanced flexibility for complex routing, and total immunity to Electromagnetic Interference (EMI), ensuring "Bit-Perfect" transmission in electrically noisy environments.
🧠 Typical Use Cases
Inter-Row Connectivity: Connecting Lenovo ThinkSystem servers in one row to core switches in another (up to 20m).
Storage Aggregation: Linking distributed NVMe-oF storage arrays to centralized compute clusters.
Campus-Scale Fabrics: Enabling high-speed, low-latency backbones for large-scale HPC or AI deployments.
 
✅ Compatible With: Lenovo and NVIDIA InfiniBand Ecosystems.
Lenovo Hardware: ThinkSystem Servers (e.g., SR630, SR650, SR850) and DB Series Switches.
Switching: NVIDIA Quantum (QM8700/QM8790) HDR InfiniBand Switches.
Protocol: Optimized for InfiniBand HDR. Supports Ethernet (200GbE) if the port configuration allows (VPI).
❌ NOT Compatible With: Legacy and Passive Constraints.
Legacy 40G QSFP+: This cable uses PAM4 signaling and is not backward compatible with NRZ-based 40G ports.
Passive Copper Applications: This is an active device requiring power from the switch port to operate the internal optical engine.
 
🌡️ Thermal & Installation Guidelines
Slack Management: 20 meters is a significant length. Use "figure-8" loops or fiber management trays to handle excess length. Do not coil tighter than a 30mm radius to avoid signal loss.
Connector Handling: The optical engines are integrated. Always use the pull-tab for insertion and removal. Do not pull on the cable jacket.
Airflow: The thin profile of the AOC (~3mm) minimizes airflow obstruction in the rack, helping to maintain optimal cooling for high-density server deployments.
