Now, it's one of the minor signs of quality I look for when purchasing off-the-shelf ethernet cables: are the 1-2 and 3-5 pairs also color pairs, or did they just punch WO-O-WBl-Bl-WG-G-WBr-Br straight across on both ends? (It matters when you have a ton of cables in a small space and want to dampen signal bleed as much as possible)</p>
<p>Hrm. I wonder how much a crimp tool and a bag of RJ45 heads would cost - I'm always snapping the little tab off ethernet cables and dealing taping or holding the cables in.</p>

<p>that was the colour code we used to use when we were still crimping our own network cables. Only the 1-2,3-5 pairs were needed and we sometimes split the cable using the extra 8-7,6-4 pairs, making two-headed cables! THAT was a monstrosity, I don't know how many standards we were violating but it worked. The end of the patch cord with two RJ45 ends went into adjacent ports of the hubs (I don't think we had switches back then), the other end was split at the wall outlets or punching panels.</p>
<p>I learned such tricks from my predecessor, Fran, who knew all the wiring tricks. She single-handedly wired 3 buildings in our department, with cat5 and fibre, always ahead of the times, when many others were still using coax.</p>
<p>Nowadays it is all done by contractors and cables are purchased, no more crimping or punching wires.</p>
