FAQs

Q: Is the 5m length passive or active?
A: This is a passive twinax DAC.

Q: What standard is supported?
A: IEEE 802.3ba 40GBASE-CR4 with MSA/SFF-8436 compliance.

Q: Will this work between any two QSFP+ ports?
A: It is standards-based, but verify that both ports support passive DAC and the 5m length.

Q: Is it hot-pluggable?
A: Yes, it is hot-pluggable with compatible hardware.

Q: When should I choose optics instead?
A: If you need distances beyond 5m or non-twinax pathways, consider optical transceivers and fiber.
