I've used 10G copper.... DACs. I won't buy a RJ45 10G server, switch,
AP, whatever. Ever. SFP+ or I'll buy something else.

The new Ignitenet stuff can do 2.5gig over copper, but I can't imagine
there's much demand for 10 gig in the wireless world... maybe in
enterprise wifi type products.
But I suspect there are uses for surge suppressors that don't involve
wireless...

My line of APC surge suppressors got invented because someone got
hit by a storm at their NOC and everything was fried. And
everything was protected by the APC rack mount surge suppressor.
They sent me the cards and asked me to see why they didn’t work.
I was already in the surge suppressor business at that point and I
did analyze the card and sent them a report. They asked me if I
could make one of the same form factor that actually did work. I
did that the rest is history.
I have been working hard to edge closer to something that is
functional on 10 Gbps circuits. I test every design on a TIA
CAT6A Perm Fixture test. Getting dangerously close to passing
that spec. In doing so, all the traces are now balanced
differential pair RF striplines with controlled impedance and
length matching etc. It has not been easy.
I recently purchased the latest APC surge protector that some
sites claim to be good to 10 Gbps. I discovered little has
changed since the early days and there is no way in hell it can do
10 Gbps. The return loss and NEXT are horrible at the higher
speeds. I am surprised it even works well at 1 Gbps.
I really want to have a comparison chart on my website comparing
my stuff with theirs. But I worry about several items:
The testing is not done by an independent third party.
(I might be fudging the data...)
I don’t want any product slander letters from their lawyers.
I really don’t want them to re-design the product so it works
(better).
I guess I can publish the technical test specs with a comparison
to an un-named similar product.
That seems silly as there are only two manufacturers that I know
of that makes cards that fit that rack.
