CAT6 protection is almost always going to be a gas discharge tube protector
on each pair. They sell the "tubes" such that each will protect one
pair. So 4 components plus a circuit board with a ton of engineering to
be able to hopefully not break CAT6 specs when doing it.

Yep, usually crosstalk.
The problem is that they've started to spec inter-pair crosstalk. That's
why cat6 has the interior plastic spacer. Which gets cut out, the 3&6 pair
gets split and the twists in the twisted pair are eliminated through the
connector.
No modern high speed design engineer
Yes, the splitting of 3&6 causes acres of trouble. But what does a good PCB do
if the jack causes the test to fail. I don’t recall which test it is, but most
jacks fail it. Might be a crosstalk.

That makes me wonder if the other guys’ “10gig” surge suppressor is going to
break what I plug into it.
I’ll tell you, compared to any other ethernet surge suppressor the 10gig model
they sell has almost nothing in it. If it works, it’s got to be the most
minimal protection imaginable.
Ahh, I quickly glanced online and somehow misread the gige as cat6. Which
is why I was confused.
I've been neck deep in the 10 gig E spec for midspan injection off and on
for the last couple of months. Not a fun read or design. Considering
going to 6 or 8 layers so I can meet some of the
Why not test for 2.5, 5 and 10g ethernet? Good marketing material if they
work?

I have not. It is nearly impossible for a surge suppressor to pass full CAT6
standards. The jacks are not even able to pass with no components.

Have you played with multi-gig ethernet?
A certain “brand T” has a model of 10gig surge suppressor and it has very few
components compared to their prior models. I was wondering if 10G is too
sensitive to put more components in the line.

All CAT6 in our product line are 100% GDT. Anything that says GIGE has solid
state and GDT. I would recommend CAT6 for everything.

Which of the MTC CAT6 surge suppressors that fit in the APC racks are
recommended for general use?
I see a Gas discharge and semiconductor diode version on the website.
Guessing the GDT version is more robust and less likely to cause errors at
the expense of reaction time.
