It is primarily used for short-distance interconnects, within a range of up to 3 meters, between 200G server network cards/switches in data centers and switches.

Yes. With the built-in ConnectX-7 (200GbE), two DGX Spark systems can be directly connected using a 0.5m 200G QSFP56 DAC cable, enabling efficient and power-saving clustering. To streamline warehouse sorting and help users quickly identify its compatibility with DGX Spark, we have exclusively upgraded the packaging of this 0.5m dedicated cable to a custom blue design. The blue packaging complements DGX Spark's iconic green packaging perfectly, making the dedicated accessory instantly recognizable. All other lengths of the same model still use standard packaging.

For cables shorter than 2 meters (0.5/1.0/1.5 meters), the AWG is 30AWG. For cables 2 meters and longer, the AWG is 26AWG.
