FAQs

Q: Is 7 meters the maximum length for passive DAC?
A: 7 m is a common maximum for passive SFP+ DAC on many platforms. For longer distances, use active DAC or optical transceivers.

Q: Will this work with my switch and server?
A: It works with SFP+ ports that support passive DAC. Refer to your device’s DAC compatibility or qualification list.

Q: Does it need special configuration?
A: No. Insert both ends into SFP+ ports; the link negotiates automatically when supported by the devices.

Q: Is latency lower than optical?
A: Yes. Passive copper provides near-zero additional latency compared to optical transceivers.
