Q: Why dual MPO‑12 connectors?
A: Each MPO‑12 services an independent 400G DR4 link, simplifying routing to separate panels or devices.

Q: Is polarity important for DR4?
A: Yes. Ensure Type‑B (key‑up to key‑up) polarity and proper pinning per your cabling design.

Q: Can I mix this with MPO‑16 cabling?
A: No. This model uses dual MPO‑12; use MPO‑12 trunks/cassettes for compatibility.
