How to set up this card from terminal or general?

Hi
Follow the download link for SLE 15 SP2 and download the source tarball, extract and rebuild the src rpms in the SRPMS directory as your user, not root!

Have you idea how to get https://www.ebay.com/itm/1-Meter-MPO-MTP-to-8XLC-Type-B-Breakout-Fiber-Otpic-Cable-OM3-40GbE-Patch-Cord/123696194054? to works from linux?

Or its only Intel XL710, 10/40GbE. that works with connect many fiber to one MPO connectior?
