Can the ends of the 200Gb/s QSFP56 DAC cable be compatible with different brands of equipment?

Yes, it is possible to match the ends of the cable with corresponding compatible devices based on the specific equipment.

Can 200G QSFP56 products be used with a 400G QSFP-DD port?

In general, 400G QSFP-DD ports are backward compatible with QSFP56, so they can be used together.

Can a DAC cable be provided for a transmission distance of 5m?

The maximum transmission distance for a 200G DAC cable is 3m. For distances exceeding 3m, it is recommended to choose AOC (Active Optical Cable) or utilize modules and fiber patch cords.

Questions & Answers

Ask a Question

What is the main application scenario for the 200Gb/s QSFP56 DAC cable?

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.

Can I directly interconnect two DGX Spark systems?

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.

What is the AWG (American Wire Gauge) of the 200Gb/s QSFP56 direct attach passive copper cable? Is it 26AWG or 30AWG?

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.

I specifically bought two of these 0.5m 200G DAC cables to connect my two DGX Spark units. I use one DAC for daily use, and the other as a backup. The single DAC delivers excellent stability and fast connectivity—no issues at all. The materials feel sturdy, and this redundancy setup gives great peace of mind. If you want reliable connectivity for your DGX Spark, grabbing two is a smart choice!

We built a compact inference cluster using DGX Spark and M3 Ultra Mac, and the overall performance exceeded expectations. The DGX Spark handles the prefill stage, delivering up to 100 TFLOPS (FP16) of compute power for high-throughput model processing, while the M3 Ultra manages the decode stage, leveraging its 819GB/s memory bandwidth for efficient KV cache handling. Although the DGX Spark’s memory bandwidth is one-third of the M3 Ultra’s, its floating-point performance is four times higher. Inspired by the VR200 NVL144 CPX design, this architecture achieves a cost-effective yet well-balanced distributed inference solution.
