🌟 NVIDIA Mellanox® NDR200 Quad-Fanout DAC
OSFP 800Gb/s → 4×200Gb/s OSFP | 2m | InfiniBand NDR200
Model: MCP7Y50-N002 | NVIDIA P/N: 980-9I46G-00N002The NVIDIA Mellanox® MCP7Y50-N002 is a passive copper quad-fanout (hydra) cable designed for InfiniBand NDR200 fabrics that remain OSFP-based end-to-end.
It converts one 800Gb/s OSFP NDR port into four independent 200Gb/s OSFP links, enabling high-density switch-to-switch, switch-to-line-card, or modular fabric fan-out without changing connector families.
This model is optimized for 2-meter deployments, offering excellent signal margin, low latency, and manageable stiffness—ideal for in-rack and short cross-rack OSFP fan-out topologies.

Signaling: PAM4
Length: 2 meters
Conductor: 28 AWG

Pulltab Color: Black
Condition: As listed (New / Refurbished per item)
🧠 Lane Physics (Why This OSFP→OSFP Fanout Works)
800G OSFP = 8 × 100G PAM4 lanes
Each 200G OSFP leg = 2 × 100G PAM4 lanes
Result: 1 × 800G → 4 × 200G (perfect electrical symmetry)
This is true NDR200, not HDR.
No lane remapping, no speed mismatch, no protocol conversion.
⚠️ Important Disambiguation: NDR200 vs HDR200
| 200G Type | Connector | Lane Structure | Compatible |
|---|---|---|---|
| HDR 200G | QSFP56 | 4 × 50G | ❌ |
| NDR200 | OSFP / QSFP112 | 2 × 100G | ✅ |
🔴 This cable is NDR200 ONLY
🔴 Not compatible with HDR / QSFP56 / ConnectX-6 hardware
📐 Radix & Scaling Insight
1 × 800G OSFP port → 4 × 200G OSFP ports
Enables 4× port density without adding switches
Common in modular Quantum-2 fabrics and OSFP-based inter-switch fan-out
🔁 Directionality (Explicit)
Upstream: OSFP 800G NDR (switch or fabric port)
Downstream: 4× OSFP 200G NDR200
This is a fan-out cable, not aggregation.
📦 Routing & Deployment Notes (2m Passive Advantage)
At 2 meters, this passive DAC:
Has better signal margin than 3m variants
Is less stiff and easier to route
Suitable for in-rack and short inter-rack paths
Still requires reasonable bend radius discipline
