FAQs

Q: Will this work with QSFP‑DD 400G switch ports from major vendors?
A: Yes, if the ports support 400G short‑reach AOC operation per QSFP‑DD MSA. Check platform release notes for AOC support.

Q: Is any fiber patching required?
A: No. It is a pre‑terminated AOC—plug directly into QSFP‑DD ports on both ends.

Q: Can it be used for 200G operation?
A: It is intended for 400G. Any down‑speeding depends on device capabilities and is not guaranteed—consult your hardware documentation.

Q: What environments is 5 m suited for?
A: Typical top‑of‑rack to spine/aggregation links within the same row or adjacent racks where 3 m is insufficient.
