Lenovo 03GX911 (MCP7Y40-N002) InfiniBand NDR200 OSFP to 4xQSFP112 Passive DAC Breakout Cable, 2m: This is a 2-meter passive copper hybrid breakout cable that splits a single 800Gb/s OSFP switch port into four individual 200Gb/s QSFP112 compute endpoints. It is a Lenovo-branded version of the NVIDIA Mellanox MCP7Y40-N002, with identical electrical specifications. The "Hybrid" designation refers to the OSFP-to-QSFP112 connector transition. This is a fixed-length integrated assembly. This unit is New.
Engineering Context
The 03GX911 is Lenovo's OEM-labeled equivalent of the NVIDIA MCP7Y40-N002 (reference P/N: 980-9I80B-00N002). At 2 meters, this cable provides a mid-range passive copper option between the 1.5m and 3m variants, allowing network architects to choose optimal reach for their rack topology. As a passive device, it consumes zero power and provides deterministic latency with complete EMI immunity via shielded twinaxial construction.
Deployment & Use Cases
Connecting Lenovo ThinkSystem AI servers or NVIDIA Quantum-2 switches (OSFP) to ConnectX-7 adapters (QSFP112) within the same or adjacent racks. High-density AI racks splitting 32 OSFP ports into 128x 200G links. HPC nodes requiring sub-microsecond latency. Environments minimizing active component thermal output and power consumption.
