FAQs

Q: Do my switch or router ports need to support breakout?
A: Yes. The host OSFP port must support 2×400G breakout and the QSFP112 ports must accept 400G.

Q: Is this cable vendor‑coded?
A: Coding can be vendor‑specific. Ensure compatibility with your platforms or use devices that accept third‑party coding.

Q: Does it require power or optics?
A: No. It is a passive copper cable with no optical components and no external power.

Q: What is the recommended application distance?
A: 1 meter; passive DACs are intended for very short, in‑rack links.

Q: Is special FEC configuration needed?
A: Use the platform’s default FEC for 400GE over copper breakout as recommended by your vendor.
