FAQs

Q: What fiber and connector do I need?
A: Use SMF with an MPO‑16 APC trunk/cassette; ensure polarity and pinning match your patching system.

Q: Does my switch need special support for breakout?
A: Yes. The 800G port must support 2x400G breakout and appropriate FEC. Check your platform release notes.

Q: Can I connect to two separate 400G DR4 ports?
A: Yes. Each 400G DR4 interface can home to a separate device or two ports on the same device.
