DGX Spark 400G QSFP112 Cable

The PNY NJAAKK-N911 is a passive direct-attach copper cable with QSFP112 connectors rated for up to 400Gbps. It measures 40cm and is certified by Nvidia for DGX Spark systems. The short length suits rack-adjacent or intra-chassis links where latency and cable bulk must stay minimal. It ships as a barebone accessory with no additional modules.

Interconnect for Certified DGX Spark Builds

This cable targets integrators and operators assembling Nvidia DGX Spark clusters, including OEM variants from Dell, HP, Lenovo, ASUS, Gigabyte and MSI. Buyers needing longer reach, active optical media, or a different connector standard should look elsewhere. The 40cm limit also rules out cross-rack or row-spanning topologies.

Certified Compatibility Only

Nvidia certification means the cable is validated for signal integrity and firmware handshake on every supported DGX Spark SKU. No driver discs, management utilities or licensing keys are bundled; the product is a passive copper assembly that works once seated in compliant ports.

Questions about this item

What port type must each DGX Spark system provide for this QSFP112 cable to connect?

Each system needs a QSFP112 port because the cable uses QSFP112 connectors on both ends.

Will the 40 cm length reach between adjacent DGX Spark units in a standard rack?

The 40 cm length is designed for close-proximity interconnects and clean routing between tightly spaced DGX Spark systems.

How can I verify the link is running at the rated 400 Gbps after installation?

Check the link status in the DGX Spark management software or OS networking tools; they will report the negotiated speed for the QSFP112 connection.
