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

SKU CH-4TQ8-Z4BYB

NVIDIA-certified QSFP to QSFP112 cable delivers 400GbE throughput for DGX Spark clustering with a 400mm LSZH jacket

  • NVIDIA-certified stacking cable for trusted DGX Spark clustering
  • QSFP to QSFP112 connectivity links AI systems directly
  • 400GbE high-speed throughput accelerates distributed workloads
  • 32AWG LSZH jacket reduces smoke emission in dense racks
  • 400mm (1.3ft) length keeps cable runs short and tidy

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.

Questions about this item

Will this 400mm QSFP112 cable reach between adjacent DGX Spark units in a standard rack?

At 400mm (1.3ft) the cable is built for tight node-to-node links inside a DGX Spark cluster; measure your rail spacing to confirm fit.

How can I confirm the link is running at 400GbE after I connect the QSFP112 ends?

Check the switch or OS port statistics — they should report a 400GbE active link with zero errors on the NVIDIA-certified cable.

Does the box include any transceivers or do I only receive the 32AWG LSZH cable?

You receive the complete QSFP-to-QSFP112 direct-attach cable; no separate transceivers are required or supplied.
