What is the NVIDIA/Mellanox equivalent of the Lenovo 03GX909?

The NVIDIA cross-reference is MCP7Y40-N001 (980-9I80B-00N001). The Lenovo 03GX909 is the OEM-branded version with identical specifications.

What lengths are available for this Lenovo NDR200 breakout cable?

Lenovo offers: 03GX909 (1m), 03GX910 (1.5m), 03GX911 (2m), and 03GX912 (3m). All are OSFP to 4xQSFP112 NDR200 passive DAC breakouts with identical specifications except length.

Is the 03GX909 compatible with ConnectX-6 adapters?

No. ConnectX-6 uses QSFP56 with 50G PAM4 signaling. The 03GX909 requires ConnectX-7 QSFP112 ports with 100G PAM4 signaling.

Lenovo 03GX909 (MCP7Y40-N001) InfiniBand NDR200 OSFP to 4xQSFP112 Passive DAC Breakout Cable, 1m: This is a 1-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-N001, with identical electrical specifications. This is the shortest length variant in the Lenovo NDR200 breakout family. This is a fixed-length integrated assembly. This unit is New.

Engineering Context

The 03GX909 is Lenovo's OEM-labeled equivalent of the NVIDIA MCP7Y40-N001 (reference P/N: 980-9I80B-00N001). At 1 meter, this is the shortest standard-length NDR200 breakout DAC, optimized for same-rack deployments where the switch and compute nodes are in immediate proximity. As a passive device, it consumes zero power and provides the lowest possible latency with complete EMI immunity via shielded twinaxial construction.

Deployment & Use Cases

Same-rack connectivity between Lenovo ThinkSystem AI servers or NVIDIA Quantum-2 switches (OSFP) and ConnectX-7 adapters (QSFP112). Maximum port density configurations splitting 32 OSFP ports into 128x 200G links. HPC nodes requiring sub-microsecond latency in tightly coupled configurations. Environments where minimizing cable bulk and thermal output is critical.
