FAQs

Q: Does this module support Ethernet (400GbE)?
A: No. It is for InfiniBand NDR fabrics and is not intended for Ethernet.

Q: What cable should I use?
A: Use OM4 or OM5 MMF with MPO‑12 APC connectors and Type‑B polarity for SR4.

Q: Is the MPO interface pinned?
A: The module presents an MPO‑12 APC female (no pins); use pinned male cables.

Q: Maximum distance?
A: Up to 50 m on OM4/OM5, subject to link budget and cabling quality.
