FAQs

Q: Is 5 m supported on all platforms?
A: Support for 5 m passive DAC can be platform-dependent; verify your switch/NIC release notes.

Q: Is it passive or active?
A: Passive Twinax DAC—no external power and minimal latency.

Q: What if I experience signal issues at 5 m?
A: Check platform firmware and DAC support lists. If needed, consider shorter DACs or optical SFP28 modules and fiber.

Q: Is it hot-swappable?
A: Yes. Follow best practices for ESD and port disable/enable procedures.

Q: Can this be mixed with breakout cables?
A: No. This is a straight SFP28-to-SFP28 cable; for breakouts use purpose-built 1×25G to 4×10G or similar cables.
