yep. Fiber is the way to go when you need 10Gbit. I was looking in to doing my place with Cat6 or 6a. Not only is 6a incredibly thick (thus, more difficult to run and probably terminate) but you need special tools and knowledge just to make sure the wiring is correct and there are no RF issues going on. It becomes way more about RF crosstalk and science, and less about simple wire connectivity.
