video How to punch down a Cat5E/Cat6 Networking 110 Keystone Jack
We review a classic problem: How to terminate Cat5 cable at a keystone jack. Our speaker, Daniel, takes the viewer through all of the steps and techniques that should be used to complete this tedious, yet important, task. Daniel had no experience with Cat5e cable coming into production of the video, but you can see that with a little practice, even a novice can install Ethernet correctly. What else can I say that the video cant say for itself?

The only pair that would pass inspection was the green and blue as they maintain the standard practice of NO MORE then 1/8th" of untwist. The Brown and Orange are not passable and I would not be able to warranty or certify that jack or any others you had done. The sheath as I can tell from the video meets the jack as required by most factory warranty and certification.
You never untwist pairs unless the jack has separated pairs. Such as a RJ45 crimp ends or older style jacks. Most modern jacks and panels keep the pairs together for this reason. You cannot re-twist the pairs once untwisted either. This is a mathematical science that has years of proven experience since CAT 3 cable and old ATT red green, black yellow, (white blue) cable.
The entire purpose of the twist is to maintain a deflection of EMI.
Home users would benefit from this but for a guarantee of high speed 100 meg (CAT 5) and 1000 meg (CAT 6) the practices you shown are not correct.
This instruct-able shows at the most connectivity but for the serious network this would not pass.
Good try though.
Check out BICSI.ORG for the world leading practices in this industry. One course is $3500.00 which is taught in 1 week (tues - thurs, testing on friday) an the entire industry and every type of jack in use.
I may have to make a Instruct-able about all of this.
