Lenovo 01PG741 (Mellanox MFS1S50-H005V) 200Gb/s to 2x100Gb/s QSFP56 Active Optical Splitter Cable, 5m: This is a 5-meter Lenovo-branded active optical cable (AOC) that splits a single 200Gb/s QSFP56 port into two 100Gb/s (HDR100) QSFP56 endpoints. Lenovo FRU part number 01PG741, cross-reference NVIDIA MFS1S50-H005V. The cable uses VCSEL optics and is a fixed-length integrated assembly. This is a refurbished unit.
Engineering Context
The 01PG741 is Lenovo's certified interconnect for HDR100 topologies in ThinkSystem environments. As a Lenovo FRU, it is recognized by Lenovo XClarity management software for native monitoring of optical levels and thermal health. The 5-meter reach enables rack-to-rack connectivity where passive copper DAC cannot maintain signal integrity at 200Gb/s PAM4 signaling rates.
Deployment & Use Cases
Connecting Lenovo ThinkSystem NVIDIA Quantum HDR switches to two HDR100 adapters. Expanding server connectivity in ThinkSystem SD530/SD650 high-density nodes. Data center interconnects requiring 5m spans where passive DAC limits are exceeded. Doubling switch port density by splitting 200G ports into two HDR100 connections.
