FAQs

Q: Is this a passive or active cable?
A: It is a passive twinax DAC.

Q: Will it work between different vendors' devices?
A: Yes, if both SFP+ ports support 10G DAC and accept the cable’s coding. Check your device’s DAC compatibility guidelines.

Q: Does it support 1Gbps operation?
A: No. SFP+ DAC is designed for 10GbE links.

Q: When should I choose DAC over AOC?
A: Choose DAC for very short runs with lowest cost and power; choose AOC when you need longer reach or better EMI immunity.
