NVIDIA Mellanox 400Gb/s NDR InfiniBand OSFP Passive Copper DAC Cable

The NVIDIA Mellanox MCP4Y10-N002 is a passive copper Direct Attach Cable (DAC) engineered for NDR (Next Data Rate) InfiniBand interconnects operating at 400 Gb/s. Utilizing OSFP (Octal Small Form Factor Pluggable) connectors, this 2-meter cable delivers high-speed GPU-to-GPU and GPU-to-switch connectivity with minimal latency and power consumption, eliminating the need for active signal conditioning on short-reach deployments.

Designed for high-volume AI and HPC cluster environments, the passive copper construction provides a cost-effective alternative to active optical solutions while maintaining full NDR InfiniBand protocol compliance. The cable supports standard network operating temperatures and is optimized for dense rack deployments where thermal efficiency and signal integrity are critical.

This DAC cable integrates seamlessly into NVIDIA GPU compute platforms and Mellanox NDR InfiniBand fabric architectures, enabling predictable, low-latency communication patterns essential for distributed deep learning, molecular simulation, and large-scale scientific computing workloads.

Ideal for

• GPU cluster interconnect for distributed AI/ML training at datacenter scale
• High-performance computing (HPC) node-to-node communication in supercomputing environments
• NVIDIA DGX and HGX GPU system fabric connectivity within 2-meter rack distances
• InfiniBand switch-to-GPU direct attachment in enterprise AI infrastructure
• Latency-sensitive numerical simulation and finite element analysis clusters
• Real-time collaborative rendering and visualization workload acceleration
