A:AnswerI assume that you're referring to the IEEE T-568 standard. A or B. Oddly enough, it matters so little as to not be a concern except for the most data intensive environment.
As long as both ends are using the same standard, it is a straight through cable. One side in A and the other in B and you have a cross-over cable. Modern equipment does not need a cross-over as it will auto cross.
CAT 6 is good up to 10 GBps for short runs and will easily do 1 GB, 2.5 and possibly 5 GBps for the length of this cable.
A:AnswerProbably nothing. Buttttt i have noticed that the insignia brand grey cables seen quite a bit more heavy duty feeling. So maybe a different braiding in the cables
A:AnswerSame cable different length equal same speed. Different brand and quality cables equals who the heck knows. You'd have to do testing on your own lol
A:AnswerIts a realistic warranty. In a month or less you should know if it works. Most companies are bought out long before "life" so saying they are warranted for that long is a joke. Cost more to send it back for replacement than a new one cost at the store.
A:AnswerI would NOT run this cable around anything unshielded. Definitely not at 100ft either. CAT6( at least this brand-at this price) seems to have less shielding than CAT 5 did. It was giving me static thru my speakers running $5K speaker cables at just 14ft. It says that it is 24 AWG on the side, but I don’t believe that since that is the same as CAT5 cables have and I’ve never had issues
