Link two DGX Spark units via their high-speed interfaces for seamless compute pool expansion up to 405B parameter models.

Switch-Based Desktop AI Clusters: Connect multiple DGX Spark workstations to a centralized 400G Ethernet switch to scale out edge AI applications and autonomous agent validation.

High-Throughput Local Dev Environments: Deliver stable, high-bandwidth data transmission for local generative AI pipelines, fine-tuning, and RAG architectures.

The Cheetah 400G QSFP112 Passive Direct Attach Copper (DAC) Cable is a premium high-speed interconnect solution explicitly validated for the NVIDIA DGX Spark Personal AI Supercomputer. Purpose-built for localized high-performance AI clustering, this 0.5-meter (50cm) passive copper assembly provides an optimal physical link between two DGX Spark systems or between a DGX Spark unit and a 400G high-speed Ethernet switch.

By leveraging the integrated NVIDIA ConnectX-7 400G network interfaces on the DGX Spark, this cable transmits data over four 105G PAM4 channels to unlock the full 400Gb/s theoretical bandwidth. This makes it the perfect hardware solution for establishing a dual-node desktop AI cluster, enabling developers and researchers to scale out local workloads from 200-billion-parameter models to massive 405-billion-parameter AI models without cloud latency or data privacy concerns.

Key Features

NVIDIA DGX Spark Validation: Tailored for seamless plug-and-play interoperability with the high-speed 400G QSFP network ports driven by the Grace Blackwell GB10 architecture.

Dual-Node Scale-Out Interconnect: Enables direct point-to-point, zero-configuration linking of two DGX Spark units via NVIDIA Sync to form a high-bandwidth local AI development cluster.

Ultra-Low Latency for Distributed AI: Delivers the near-zero latency, low insertion loss, and minimal crosstalk essential for performance-sensitive parallel computing, multi-node inference, and distributed training workloads.

0.5-Meter Optimized Desktop Layout: The 50cm ultra-short length is perfectly sized for side-by-side or stacked desktop configurations, avoiding messy cable slack, reducing rack clutter, and maximizing cooling efficiency.

Passive Power Efficiency: Consumes less than 0.03W of operating power, requiring zero external energy and adding no active thermal load to the compact 150mm desktop chassis.

High-Speed Connectivity: 400G QSFP112 passive cable assembly delivers ultra-fast data transfer for demanding network environments.
Wide Compatibility: Designed to meet the needs of next-generation 2X100G switches, servers, routers, and other network applications.
Passive Design: Passive cable assembly ensures low power consumption while maintaining reliable high-bandwidth signal transmission.
Future-Ready Performance: Built to support next-generation network infrastructure requirements with advanced PAM-4 modulation technology.
