The [Blackmagic UltraStudio 4k Extreme](https://www.blackmagicdesign.com/products/ultrastudio) has some [SFP](https://en.wikipedia.org/wiki/Small_form-factor_pluggable_transceiver) ports.

Is it possible for that device to **record to a network location** like a NAS or SAN directly using a **fibre connection**?

Or is the fibre connection just used as another way to connect to a Mac or PC which would then do the recording?
