NVIDIA Mellanox 400GbE QSFP112 to QSFP112 Passive Copper DAC Cable

The NVIDIA Mellanox MCP1660-W001E30 is a 400GbE passive direct-attach copper (DAC) cable engineered for ultra-high-density data center interconnect. It features QSFP112 connectors on both ends, enabling seamless integration with Mellanox Spectrum switches and compatible server network adapters without requiring active signal conditioning or external power.

This passive copper implementation delivers line-rate 400 gigabit throughput over a 1-meter span, optimizing for short-reach switch-to-server and switch-to-switch deployments typical in modern enterprise and hyperscaler fabric architectures. The cable's passive design minimizes latency while reducing operational complexity and heat generation compared to active alternatives.

Ideal for

• High-performance compute cluster interconnect within enterprise data centers
• Top-of-rack (ToR) switch to server blade connectivity in dense server environments
• Switch fabric aggregation for multi-petabyte parallel storage systems
• Low-latency financial trading infrastructure requiring sub-microsecond fabric delays
• AI/ML training clusters demanding sustained 400GbE throughput between compute nodes
• Research and scientific computing environments with tightly-coupled distributed workloads
