Questions about this item

What does the 25Gb Ethernet rating mean when the card is installed in a server?

The adapter provides a single 25Gb Ethernet link over multimode fibre using an MPO/UPC connector, so throughput is limited to 25Gb/s per port once cabled and configured.

Which PCI Express interface does the card use and what bandwidth ceiling does that impose?

The card plugs into a PCI Express slot; the practical ceiling is the lane width and generation of that slot, which together cap the maximum host-to-card data rate.
