FAQ

What's the maximum distance?

This is a 1m (3ft) passive copper DAC, intended for short in-rack server-to-switch NDR links.

Is it OSFP or QSFP-DD?

It is an OSFP flat-top cable for NVIDIA NDR gear like ConnectX-7 and Quantum-2 switches.

Does it need power or drivers?

No, passive DAC cables draw no power and require no transceiver firmware; they appear as direct copper links.
