FAQs

Q: Is this cable passive or active?
A: Passive Twinax DAC; no external power required.

Q: Will it interoperate with different vendors’ SFP28 ports?
A: It follows MSA for SFP28, but platform DAC whitelists can apply—confirm support on your target device.

Q: What’s the best alternative for longer runs?
A: Use optical SFP28 transceivers and fiber (e.g., SR over OM4 up to ~100 m) for longer distances.

Q: Is it hot-swappable?
A: Yes, follow your platform’s recommended hot-swap procedure.

Q: Any bending or routing precautions?
A: Maintain a bend radius ≥10× cable diameter and avoid crushing or kinking the Twinax.
