FAQs

Q: Does the host need to support 2×400G breakout?
A: Yes. The OSFP port must be capable of 800G split into two 400G ports, and the receiving ports must accept QSFP112 400G.

Q: Is cross‑vendor operation supported?
A: It depends on coding and platform policies. Confirm compatibility or use platforms that allow third‑party coded DACs.

Q: Is this cable active or passive?
A: Passive. It contains no retimers and provides the lowest possible latency.

Q: What distance is supported?
A: 2 meters, suitable for short intra‑rack or adjacent rack runs.

Q: Any FEC requirements?
A: Follow your platform’s recommended FEC settings for 400GE PAM4 over copper breakout.
