Performance tier: High-performance
Uses: DGX Spark stacking, AI system interconnects, dual-node connections, GB10 system connectivity, high-speed data links Overview
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.
Description
The PNY DGX Spark ConnectX-7 Connector Cable provides a direct, high-speed connection between NVIDIA DGX Spark systems and compatible GB10-based AI platforms. Its passive DAC design keeps the setup simple, requiring no additional transceivers or network switch for a direct node-to-node connection.
With QSFP112 connectors on both ends and a 400G-rated design supporting four 100G lanes, the cable is built for high-bandwidth AI networking. When used with DGX Spark and other GB10 systems equipped with ConnectX-7 QSFP ports, it can operate at up to 200 Gb/s per port.
The compact 40 cm length is particularly well suited to desktop AI workstations positioned next to each other, helping avoid unnecessary cable length while keeping the connection neat.
Features
NVIDIA DGX Spark Stacking Cable
This PNY cable is one of only two options listed by NVIDIA as approved for stacking DGX Spark systems. It offers a straightforward way to create a high-speed link between two compatible systems without introducing additional networking hardware.
The cable is suitable for a range of GB10-based platforms, including:
- NVIDIA DGX Spark
- HP ZGX Nano AI Station
- Dell Pro Max with GB10
- ASUS Ascent GX10
High-Speed QSFP112 Direct Connection
The passive direct-attach copper construction is designed for simple point-to-point connectivity. Both ends use QSFP112 connectors, allowing the cable to connect directly to compatible ConnectX-7 QSFP ports.
There is no requirement for an external switch, optical transceivers or additional adapters when establishing a compatible direct connection. This makes the cable a practical choice for compact dual-system AI deployments where a dedicated high-speed link is required.
