<br>
10GBase-T is out of Voltage Spec with SFP+ ; you can get copper SFP+<br>
but they are out of spec... 10GbaseT doesn't really work over Cat5e<br>
more than a couple of meters (if you are lucky) and even Cat6 is only<br>
rated at 30M... there is a reason no-one is producing Home Copper<br>
switches and it's not just the NIC Silicon cost (that was a factor<br>
until Recently obviously, but only part of the equation).<br>
<br>
On the flip side:<br>
Right now I am typing this via a 40gbit network, comprised of the<br>
cheap and readily available Tb3 port - it's daisy chained and limited<br>
to 6 ports, but right now it's easily the cheapest and most effective<br>
port. Pitty that the fabled optical tb3 cables are damn expensive...<br>
so you're limited to daisy-chains of 2m. They seem to have screwed the<br>
pooch on the USB-C network standard quite badly - which looked so<br>
promising, so for the moment Tb3 it is for me at least.<br>
