FAQs

Q: Is this an Ethernet 800G module?
A: No. It provides two 400G NDR InfiniBand SR4 links within a single OSFP module.

Q: Do I need two separate MPO trunks?
A: Yes. Each NDR SR4 link uses its own MPO‑12 APC MMF trunk with Type‑B polarity.

Q: Will this fit in any OSFP slot?
A: Use in OSFP ports that support the required thermal and power envelope for finned NDR optics.

Q: Are the two 400G links independent?
A: Yes, each MPO interface presents an independent 400G NDR SR4 link.
