I don't think cat7 or cat8 are officially recognized standards. I may be wrong, but I think that means these companies can get away with using these terms for marketing without the cables actually being made to some higher specs or standards.

Also watch out for CCA (copper-clad aluminum) conductors. If it seems like a cable "should" cost more but doesn't, there is usually a good chance you are missing something.

that and the general way they eliiminate crosstalk is having more twists per foot of cable which leads to a thicker cable.


you could run 12 Cat5e in a 1" hole in the top plate vs 4 Cat6a also

Nope. I've been in the cabling business close to 20 years, 6A is the highest recognized standard we use as of now. These are getting better with companies such as General Cable and Commscope coming out with small diameter versions as well as slowly increasing 10 Gig distance.

I think Corning has a Cat 7/7A certified offering but I have heard there are challenges using it.
