Home Electronics Adapters & Cables NVIDIA Mellanox MCP4Y10-N00A 800G NDR Passive DAC Cable

NVIDIA Mellanox MCP4Y10-N00A 800G NDR Passive DAC Cable

Brand:
NVIDIA Mellanox

The NVIDIA Mellanox MCP4Y10-N00A is a 0.5-meter passive direct-attach copper cable for NDR InfiniBand connectivity, supporting up to 800Gb/s through a twin-port 2×400Gb/s OSFP-to-OSFP configuration. It is designed for short, high-bandwidth connections in AI, GPU, HPC, and data-center fabrics. NVIDIA lists the cable as a mass-production NDR product.

OVERVIEW

  • The MCP4Y10-N00A is a 0.5m passive copper DAC for twin-port NDR InfiniBand, delivering up to 800Gb/s through OSFP connectivity. Compatibility: intended for supported NVIDIA NDR InfiniBand platforms using compatible OSFP interfaces. Model comparison: the N001, N01A and N002 variants provide 1m, 1.5m and 2m lengths. Choose N00A when very short rack connections are required.

USE CASES

  • AI GPU clusters - Short 800G copper links help connect high-performance compute infrastructure within the same rack.
  • NDR InfiniBand fabrics - Provides a direct OSFP-to-OSFP copper connection for supported NDR deployments.
  • HPC clusters - Supports high-bandwidth interconnect requirements between compute and fabric components.
  • GPU server networking - Useful where servers and InfiniBand switches are positioned close enough for a 0.5m DAC.
  • NVIDIA Quantum-2 environments - Provides a compatible cable option for supported NDR switch architectures.
  • High-density data centers - The 0.5m length helps avoid unnecessary cable slack in short rack interconnects.
  • Rack-scale AI infrastructure - Supports compact cabling between adjacent networking and compute equipment.
  • NDR fabric expansion - Enables additional short-distance links as GPU and HPC infrastructure scales.

Why Choose This Product?

  • 800G-class NDR connectivity – Provides up to 800Gb/s aggregate bandwidth for demanding AI and HPC infrastructure.
  • Purpose-built for short connections – The 0.5m length is practical for adjacent rack components and helps minimize excess cable.
  • Passive copper design – Avoids active optical components for these short-reach connections.
  • Dual 400G architecture – Supports twin-port 2×400Gb/s NDR connectivity through OSFP interfaces.
  • High-density rack deployment – Compact cabling is well suited to tightly packed GPU and InfiniBand environments.
  • NVIDIA-qualified product family – Provides a native NVIDIA cable option for supported NDR platforms rather than relying on generic cabling.
  • Multiple length options – The MCP4Y10 family provides 1m, 1.5m and 2m alternatives when 0.5m is not sufficient.
