AFAIK, both are exactly the same electrically, only the polarity

B or A to A it is straight through. Wire A to B then it is a
cross-over.
Actually, not at all. Swapping green and orange swap whole pairs,
not
swap wires within each pair.
I think the difference is in the number of twists per foot in the
green and orange pairs (orange has more). If the TPF match the
blue
or brown pairs, you get more crosstalk, so using the correct pairs
may
result in less crosstalk.
No question we have to do a full analysis of all factors! bg
I'm going to be doing a 200+ ft run in a month or so to the new
garage, and will try both ways and see if one is more reliable
than
the other (I've got four cables run, only need one of them...)
Here is a LCOM link that would help on lighting protection.

Lighting protection?
Surge devices are not for "Lightning Protection" as a lightning
stroke
would indeed make it all the way into your product if it hit.
Surge protection devices are just that. Protection from surges,
and
only then, up to a certain point.
OK show me a lighting arrestor for Cat6(5e).
That is what I said. I said that there is NO SUCH THING.
Do you have reading issues?
No reading issues here, it's just that you never stated that there is
'NO SUCH THING'.
Cheers
What part of "surge devices are not for lightning protection" do you not
understand?
So, yes, you DO have reading problems,because your response treated my
post as if I was stating that lightning does get 'arrested' by such
devices. I never made any such statement. Jeez...learn to read.
