Lenovo 01PG736 (MFS1S00-H020E) InfiniBand HDR 200Gb/s QSFP56 Active Optical Cable, 20m: This is a 20-meter active optical cable (AOC) engineered for 200Gb/s InfiniBand HDR point-to-point interconnectivity. It is a Lenovo FRU-branded version of the NVIDIA Mellanox MFS1S00-H020E, with identical electrical and optical specifications. The cable incorporates VCSEL optical engines directly into the QSFP56 connector shells. This is a fixed-length integrated assembly, not a transceiver with a detachable patch cord. This is a refurbished unit.
Engineering Context
The 01PG736 is Lenovo's OEM-labeled equivalent of the Mellanox MFS1S00-H020E (reference P/N: 980-9I45A-00H020). At 20 meters, it enables inter-row connectivity in large data centers where passive copper at 200Gb/s PAM4 speeds is physically impossible. The cable uses multi-mode fiber and provides complete EMI immunity. Each connector includes integrated EEPROM for SFF-8636 diagnostic monitoring of temperature, optical power, and bias current.
Deployment & Use Cases
Inter-row InfiniBand HDR connectivity within Lenovo ThinkSystem server environments. Connecting Lenovo DB Series or NVIDIA Quantum HDR switches to ConnectX-6 HDR adapters across data center rows. Storage aggregation linking distributed NVMe-oF storage arrays to centralized compute clusters. HPC and AI/ML training clusters requiring 20m reach 200Gb/s links.
