Cheetah 400G QSFP112 Passive Direct Attach Cable (DAC Cable) for nVidia DGX Spark – 0.5 Meters

Original price was: ₹25,000.00.Current price is: ₹15,000.00.

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.
