Pny Dgx Spark Connect X 7 Connector Cable 40 Cm

NVIDIA DGX Spark approved stacking cable | QSFP112 passive DAC | 400G-rated | 40 cm direct-attach copper | No switch required

The PNY DGX Spark Connector Cable is a QSFP112 passive direct-attach copper (DAC) cable purpose-built for connecting two NVIDIA DGX Spark systems — or compatible GB10-based units — directly through their ConnectX-7 QSFP ports, with no switch, transceivers, or additional adapters required. At 40 cm in length, it is the ideal reach for two compact desktop AI systems placed side by side. NVIDIA lists this cable as one of only two approved options for DGX Spark stacking, making it the straightforward, verified choice for a dual-node interconnect. The cable is rated at 400G (4 x 100G lanes) with QSFP112 connectors on both ends; on DGX Spark and OEM GB10 platforms the link operates at up to 200 Gb/s per port, as the ConnectX-7 QSFP port is the determining factor. Plug in and connect — no configuration complexity, no compatibility guesswork.
