FAQs

Q: When should I choose passive vs active DAC?
A: Choose passive for shortest links and lowest power/latency. Use active for longer copper reaches where additional signal conditioning is needed.

Q: Do I need separate SFP+ transceivers?
A: No. The SFP+ connectors are built into the cable.

Q: Is 1 meter enough for TOR to server?
A: Yes for most in-rack deployments where devices are in the same cabinet.

Q: Will this work across different vendor devices?
A: It can, but vendor-specific EEPROM coding may be required. Verify compatibility for both ends.

Q: Can I use this for storage and vMotion traffic?
A: Yes—10GbE passive DAC is commonly used for storage, vMotion, and server interconnects within a rack.
