LENOVO Mellanox® 01PG735(MFS1S00-H015E) Active Optical Cable: This is a fixed-length integrated cable assembly, not a transceiver with a detachable patch cord. Designed for long-reach inter-rack connectivity in high-performance computing (HPC) environments, this 15-meter Active Optical Cable (AOC) delivers 200Gb/s throughput using QSFP56 connectors. It leverages multimode fiber and integrated VCSEL technology to transmit high-bandwidth HDR signals over distances that are physically impossible for passive copper cables.

🌐 Engineering Context: The 01PG735 is engineered for "Cross-Row" or "Core-to-Edge" network topologies. At 15 meters, this cable bridges the gap between separate server rows or connects centralized storage racks to compute clusters. Compared to equivalent copper solutions, AOC offers lower weight (eliminating rack sag), significantly tighter bend radius, and superior long-term signal stability due to "EMI Immunity". It ensures reliable data transmission in electrically noisy data center environments.
🧠 Typical Use Cases
Cross-Row Interconnects: Linking Lenovo ThinkSystem servers in one row to core aggregation switches in another (up to 15m).
Centralized Storage: Connecting high-performance NVMe storage arrays to distributed compute nodes.
Large-Scale Clusters: Facilitating the backbone connectivity for massive HPC or AI training deployments.
 
✅ Compatible With: Lenovo and NVIDIA InfiniBand Ecosystems.
Lenovo Hardware: ThinkSystem Servers (e.g., SR650, SR670) 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 lasers.
 
🌡️ Thermal & Installation Guidelines
Slack Management: Managing 15 meters of cable requires care. Use "figure-8" loops or fiber management trays to handle excess length. Avoid tight coils (< 30mm radius) to prevent signal loss.
Connector Handling: The optical engines are integrated into the connector. Always use the pull-tab for insertion and removal. Do not pull on the orange fiber jacket.
Airflow: The slim profile of the AOC (~3mm) allows for better airflow in the rack compared to bulky copper cables, helping to maintain optimal operating temperatures.
