🌟 NVIDIA Mellanox® MCP7Y40-N003 | 800Gb/s to 4×200Gb/s Passive Breakout Cable (DAC) | OSFP to 4×QSFP112 | 3m | InfiniBand NDR200
Product Overview
The NVIDIA Mellanox® MCP7Y40-N003 (P/N: 980-9I75R-00N003) is a high-density 1-to-4 passive breakout cable designed for InfiniBand NDR200 deployments. It converts a single 800Gb/s OSFP NDR port into four independent 200Gb/s QSFP112 (NDR200) links, enabling efficient multi-node fan-out from a single switch port.
With a reach of 3 meters, this cable supports flexible rack-to-rack or top-to-bottom connectivity in AI clusters, HPC systems, and modern data center fabrics where high bandwidth and maximum port utilization are required.
Because this is a long-reach passive DAC, the cable is significantly thicker and less flexible than short NDR DACs. Proper routing planning is recommended for best performance and mechanical reliability.
Key Features
1. True NDR200 Breakout (800G → 4 × 200G)
Provides four dedicated 200Gb/s NDR200 connections from a single OSFP NDR port, increasing port efficiency and infrastructure density.
2. High-Density 1-to-4 Connectivity
Designed for topologies where a single NDR switch port must service multiple servers, accelerators, or storage endpoints—ideal for scale-out AI clusters.
3. Passive Copper Architecture
Zero-power, zero-latency design ensures optimal performance, reduced thermal footprint, and improved long-term reliability.
4. LSZH Jacket for Data Center Compliance
The Low Smoke Zero Halogen design supports stringent fire-safety requirements found in modern enterprise and hyperscale facilities.
5. Extended 3-Meter Reach
Suitable for wider rack layouts, cross-cabinet wiring, and distributed computing pods where 1-meter or 2-meter cables are insufficient.

Application Scenarios
This breakout cable is commonly used to:
• Connect one switch port to four servers or GPU nodes
• Expand NDR switch connectivity without additional switching hardware
• Build high-density AI and HPC clusters
• Deploy rack-scale or pod-scale NDR200 infrastructures
• Enable efficient leaf–compute fan-out in InfiniBand fabrics
Compatibility
Compatible with:
• NVIDIA Quantum-2 NDR switches (OSFP)
• NVIDIA ConnectX-7 QSFP112 adapters (200Gb/s)
• NDR200-capable compute, GPU, and storage nodes
Not compatible with:
• Ethernet QSFP-DD (400GbE)
• QSFP56 HDR devices
• Any non-InfiniBand systems
Routing Advisory
Due to its 3-meter passive copper construction, the cable is:
• Significantly thicker and stiffer than shorter NDR DACs
• Not recommended for tight bends or cable management arms (CMAs)
• Best suited for planned, straight-path routing across racks or within structured cabling trays
Proper strain relief is advised at the OSFP head and the quad-branch Y-junction.
