FAQs

Q: Is this cable active or passive?
A: It is a passive twinax DAC; it has no active electronics.

Q: Will it work in an SFP28 25G port?
A: Some SFP28 ports support 10G operation with DACs, but this is platform-dependent. Check your device documentation.

Q: When should I use a DAC instead of fiber?
A: Use DACs for very short, in-rack links where lowest latency, cost, and power are preferred.
