Here are some things I've learned over the years about making cable, and some ways I try to ensure I don't screw it up:

1) Be VERY careful not to nick the inner wire insulation when removing the PVC sheath
2) My technique is to unravel about 1" of each twisted pair, get the conductors in order, then cut off the excess to make a perfectly straight line. This ensures all 8 conductors go all the way to the wall of the RJ45 plug before crimping
3) Visually confirm that all 8 conductors make it to the wall of the plug
4) Visually confirm that the jacket extends into the plug about 1/8" beyond the crimp body
5) Be very careful pulling the cable from the box, so that you don't kink the cable anywhere.

This has worked very well for me over the years. Also, as another stated, make sure you get the pinout right according to 562A/B.

I'm having some issues with a new box of 1000' cat5e cable and was wondering if anyone on here could provide some advice. I know this isn't exactly a Linux question but it's general networking and I figured it would be in the same ballpark for many of you :)

Anywhoo, a lot of the patch cables I am making is failing to light up the 'link' lights when I plug them into various devices. I have made a couple successful ones that work but the majority of them are a huge headache and are not working. The weird part is we have two cat5 network cable testers here, both of them confirm that all my lines match up and that both ends of the cable are identical (one of the devices even gives me an accurate reading of the cable lengh). Still though I have issues plugging these into devices. At this point I'm wondering if there's something wrong with the cable, or wrong with the RJ45 end pieces, or a weird combination of both. Do Cat5e cables require a different rating/class/whatever of RJ45 ends than cat5 cables? I don't seem to have this issue when I'm making traditional cat5 patch cable...

Thanks in advance for any pointers.
