🌟 NVIDIA Mellanox® MCP7Y50-N02A | 800Gb/s to 4×200Gb/s Passive Breakout Cable (DAC) | 2.5m | OSFP → 4×OSFP | Flat-Top | InfiniBand NDR / NDR200
Product Overview
The NVIDIA Mellanox® MCP7Y50-N02A (P/N 980-9I46U-00N02A) is a 1-to-4 passive splitter cable engineered for InfiniBand NDR/NDR200 environments. It converts a single 800Gb/s OSFP NDR interface into four independent 200Gb/s OSFP NDR200 links—ideal for high-density AI clusters, liquid-cooled platforms, and OSFP-based compute environments requiring multi-node fan-out.
At 2.5 meters, this passive DAC offers an extended reach for complex rack layouts while maintaining full InfiniBand NDR200 signal performance. Its Flat-Top OSFP connector design is optimized for blade chassis, liquid-cooled nodes, or any environment where finned (RHS) heat sinks are not required.
Key Features
🚀 True NDR200 Breakout (800G → 4×200G)
Breaks out eight 100G PAM4 lanes into four independent links:
Each leg = 2×100G PAM4 lanes (200Gb/s NDR200).🔌 OSFP on ALL Ends — Specialized Thermal Deployment
All five connectors (1 input + 4 outputs) are OSFP.
This is used in environments where:
QSFP112 is not supported,
OSFP cages offer greater thermal headroom,
Compute nodes or blades are liquid-cooled,
Uniform OSFP cabling is preferred across GPU trays or midplanes.
⚡ Passive Copper Design (Zero Power, Ultra-Low Latency)
No electronics →
• Zero added latency
• No power consumption
• High reliability
• Lower thermal load vs. ACC/AOC
📏 Extended 2.5m Reach
Perfect for:
Connecting distributed GPU trays
Middle-of-rack to top-of-rack layouts
Pod-level breakout
Mixed cooling zones within liquid-cooled aisles
🔥 LSZH Data-Center-Safe Jacket
Meets low-emission requirements for hyperscale and enterprise environments.
🧊 Flat-Top OSFP Construction
Optimized for non-air-cooled environments.
Not recommended for air-cooled OSFP switch ports requiring RHS/finned modules.

Ideal for mission-critical, bandwidth-intensive AI workloads
Suitable for dynamic, thermally optimized data center designs
⚠️ Passive Cable Routing Advisory
A 2.5m passive 800Gb/s breakout requires thicker copper to maintain signal integrity.
This cable is therefore:
Thick and semi-rigid (much stiffer than standard DAC cables)
Not suitable for tight bending or cable-management arms
Best routed in structured cabling trays
Requires careful strain-relief at both OSFP ends and at the 1→4 breakout junction
Providing this warning helps prevent incorrect installation and premature return requests.
