Yes. This SFP+ card is genuine and arrived in excellent condition. Both the card and the modules work well. Installed into Windows 10 machine and it immediately connected to the internet and installed the drivers. Then switched to fibre and now can edit video from my 10GB NAS/switch.
Plug and Play for both Windows and FreeBSD. Manageable heat levels compared to 10 GB BASE-T. The included transceivers works like a charm. Jumbo frames capable and great for home use.
Installed in my pfsense box and it works without a hitch. The only thing that kinda stunk was one of the retention arms on a transceiver snapped off, but that's probably due to my inexperience in working with fiber rather than a problem with the transceiver itself.
