AAAwave NVIDIA Certified QSFP-QSFP112 400GbE 32AWG LSZH 400mm 1.3ft DGX Spark Cable

NVIDIA Certified DGX Spark Cable

This cable is an NVIDIA certified stacking interconnect built for DGX Spark AI systems. It provides a direct QSFP to QSFP112 link between nodes for distributed training and data synchronization. The 1.3ft length keeps the signal path short inside dense rack configurations. It is not suited for longer runs or non-DGX Spark equipment.

400GbE Throughput and 32AWG Construction

The assembly supports 400GbE high-speed throughput across its 400mm span. The 32AWG conductors with a low-smoke zero-halogen jacket meet strict data-centre fire safety requirements. Headroom is defined by the certified 400GbE rate; workloads exceeding that bandwidth will require additional links or a different interconnect class.

Thermals Noise and Power Draw

As a passive copper assembly, the cable draws no power and generates no audible noise during operation. Heat dissipation is limited to minimal resistive loss across the 400mm length under full 400GbE load. No active cooling or airflow management is required for normal use in a DGX Spark cluster.
