NVIDIA Mellanox® MCP7Y60-H002 (NVIDIA P/N 980-9I46L-00H002) is a passive copper splitter DAC that breaks one OSFP HDR 400Gb/s aggregate port into two independent QSFP56 200Gb/s HDR ports. It IS an InfiniBand HDR breakout cable; it IS NOT a 400GbE Ethernet cable, an NDR (QSFP112) cable, or an active optical cable. Condition: New.
Engineering Context. The OSFP side carries 8 lanes of 50Gb/s PAM4 (400Gb/s aggregate). Each QSFP56 leg receives 4 lanes of 50Gb/s PAM4 = 200Gb/s HDR. Conductor is 26AWG twinax with an LSZH (Low Smoke Zero Halogen) jacket. Length is 2m. Being passive copper, it draws no power on the host side and adds essentially zero latency relative to the underlying SerDes.
Deployment & Use Cases. Used to fan one OSFP 400G port on an NVIDIA Quantum HDR switch out to two HDR200 endpoints such as ConnectX-6 adapters. Typical workloads: InfiniBand HDR HPC clusters, AI training fabrics with HDR200 GPU nodes, and high-density GPFS/Lustre storage networks where doubling effective port radix matters more than per-link bandwidth headroom.

Compatibility & Constraints. Compatible with NVIDIA Mellanox Quantum HDR OSFP switch ports on the OSFP end and HDR200 QSFP56 endpoints (e.g., ConnectX-6 HDR200) on the leg side. NOT compatible with NDR/QSFP112 ports, 400GbE QSFP-DD Ethernet ports, or HDR100 single-port operation. As a passive copper cable, reach is fixed at 2m; for longer reach use an active or optical equivalent.
