FAQs

Q: Is 3m suitable for passive DAC at 800G/400G?
A: Yes. This assembly is designed for short‑reach passive operation at the specified 3m length on supported NDR ports.

Q: Do I need special drivers or licenses?
A: No licenses are required for the cable; ensure your ports support NDR breakout operation.

Q: Can each 400G leg connect to a different device?
A: Yes. Each leg functions as an independent 400G link to a compatible QSFP112 port.
