Nvidia MCP7Y10-N003Compatible with 800G OSFP to 2x400G QSFP112 DAC Cable, 3m(10ft)

• 800G to 2x400G Breakout Connectivity

Splits a single 800G OSFP port into two independent 400G QSFP112 links. It delivers 800Gbps aggregate bandwidth for NDR InfiniBand and 800G/400G Ethernet solutions, maximizing port utilization in AI and HPC clusters.

• Passive Design for Zero Latency & Ultra-Low Power

Built as a direct-attach copper cable with no active electronics, it achieves near-zero latency and OSFP ends each consume 0.1 Watts. This makes it ideal for latency-sensitive workloads like AI training, offering superior efficiency over optical solutions.

• Seamless NVIDIA Ecosystem Integration

Features a Twin-port OSFP connector for Quantum-2/Spectrum-4 switches and two QSFP112 connectors for ConnectX-7 adapters and BlueField-3 DPUs. Supports CMIS-based auto-negotiation for hot-plug and dual-mode (InfiniBand/Ethernet) operation.

• Rack-Optimized Deployment

The 1.5-meter length and 26AWG gauge are engineered for flexible in-rack server-to-switch connections. Its lightweight design simplifies cable management in high-density data center environments.

• Cost-Effective High-Speed Interconnect

For short-reach applications under 3 meters, this DAC provides the lowest total cost of ownership compared to optical transceivers, making it the budget-friendly choice for building NVIDIA DGX systems and GPU compute pools.
