🌟 NVIDIA Mellanox® MCP7Y50-N003 | 800Gb/s to 4×200Gb/s Passive Breakout Cable (DAC) | 3m | OSFP → 4×OSFP | Flat-Top | InfiniBand NDR / NDR200
Product Overview
The NVIDIA Mellanox® MCP7Y50-N003 (P/N 980-9I46T-00N003) is a high-density 1-to-4 passive breakout cable engineered for InfiniBand NDR and NDR200 deployments. It converts a single 800Gb/s OSFP NDR port into four independent 200Gb/s OSFP NDR200 links, providing exceptional scalability for AI fabrics, HPC clusters, and enterprise compute environments.
With a 3-meter reach, LSZH safety certification, and Flat-Top OSFP connectors, this splitter enables flexible rack layouts where servers, accelerators, and switch ports are positioned farther apart than standard 1m deployments.
Because this is a long-reach passive copper harness operating at 800Gb/s, it is significantly thicker and less flexible than active solutions. Proper cable-routing planning is required.
Key Features
🚀 True NDR200 Quad Breakout (800G → 4×200G)
Each of the four outputs delivers 200Gb/s NDR200, using:
2 × 100G PAM4 lanes per leg (correct NDR200 lane assignment).🔌 OSFP on ALL Ends – Specialized Deployment
Most 200Gb/s nodes use QSFP112, but this cable is designed for environments where:
Compute nodes use OSFP cages
OSFP is preferred for thermal headroom
Systems use liquid cooling or flat-top OSFP modules
Blade and accelerator platforms require uniform OSFP porting
⚡ Passive Copper Design (Zero Power, Zero Latency)
No internal electronics →
No added latency
No power consumption
Higher long-term reliability
Lower thermal load compared to ACC/AOC alternatives
📏 Extended 3-Meter Reach
Ideal for:
Rack-to-rack or pod-to-pod layouts
Distant GPU trays
Liquid-cooled compute clusters
Infrastructure where 1m and 2m cabling is not sufficient
🔥 LSZH Safety Construction
The flame-retardant, low-toxicity jacket meets modern data center standards.
🧊 Flat-Top OSFP Design
For systems where RHS (finned-top) heat sinks are not required.
Not recommended for air-cooled OSFP cages.

Compatibility Notes
✅ Compatible With
• NVIDIA Quantum-2 NDR OSFP switches
• OSFP-based NICs, compute nodes, accelerator trays
• Liquid-cooled or thermally stabilized environments
❌ Not Compatible With
• Ethernet networks (QSFP-DD / OSFP-800GbE)
• InfiniBand HDR (200Gb/s) – electrically different from NDR200
• QSFP112-based servers or NICs
• Air-cooled OSFP cages requiring RHS heat sinks
Cable Routing Advisory (Important)
At 3 meters, a passive 800Gb/s splitter is:
Thick and mechanically stiff
Not suitable for tight bends or CMAs (cable management arms)
Best routed along structured cable trays
Requires careful strain-relief at OSFP heads and the 1→4 breakout junction
