NVIDIA Mellanox® MCP7Y40-N003 (NVIDIA P/N 980-9I75R-00N003) is a passive copper fanout (hybrid breakout) DAC that splits one OSFP 800Gb/s NDR port into four QSFP112 200Gb/s NDR200 legs. It IS an InfiniBand NDR / NDR200 1-to-4 fanout cable; it IS NOT compatible with HDR (QSFP56), Ethernet QSFP-DD, or AOC connections. Condition: New.

Engineering Context. The OSFP trunk carries 8 lanes of 100Gb/s PAM4 (800Gb/s aggregate). Each QSFP112 leg receives 2 lanes of 100Gb/s PAM4 = 200Gb/s NDR200. Length is 3m, jacket is LSZH, pulltab color is black. Passive copper construction means no host power draw on the cable assembly and no signal-conditioning electronics. 3m is at the upper edge of practical passive copper reach for 100Gb/s-per-lane PAM4, so cleanly routed paths and adequate strain relief at the OSFP head and Y-junction are recommended.

Deployment & Use Cases. Used to fan one OSFP 800G port on an NVIDIA Quantum-2 NDR switch out to four ConnectX-7 NDR200 endpoints, increasing effective port radix by 4x without adding switches. Typical workloads: AI training fabrics with NDR200 GPU/compute nodes, dense leaf-to-compute fanout in InfiniBand fabrics, and pod-scale or rack-scale NDR200 deployments.

Technical Specifications.

  • Cable type: Passive copper fanout DAC (twinax)
  • Topology: OSFP (NDR) to 4x QSFP112 (NDR200)
  • Aggregate data rate: 800Gb/s
  • Per-leg data rate: 200Gb/s NDR200
  • Signaling: 100Gb/s PAM4 per lane
  • Protocol: InfiniBand NDR / NDR200
  • Length: 3m
  • Jacket: LSZH
  • Pulltab color: Black
  • NVIDIA Part Number: 980-9I75R-00N003

Compatibility & Constraints. Compatible with NVIDIA Quantum-2 NDR OSFP switch ports on the trunk side and QSFP112 NDR200 endpoints (e.g., ConnectX-7) on the leg side. NOT compatible with HDR / QSFP56 / ConnectX-6 systems (HDR200 is electrically different despite the shared 200G headline), 400GbE QSFP-DD Ethernet ports, or any non-InfiniBand fabric. 3m is the upper edge of passive copper reach for NDR200; for poorly managed routes consider ACC or AOC alternatives.
