[QUOTE="PBC_1966, post: 114284, member: 7302"] No more so than between the transmit and receive sides of the same link in a single cable which are running on adjacent pairs, or between long runs of bundled cables to different jacks. The reason for the different number of twists per inch in each pair in data cable is to minimize the capacitance between the conductors to reduce crosstalk, but with the relatively low impedances involved, it's unlikely to be a problem. It's a useful trick if you need to add a second data jack at a specific location and running another cable would be very awkward. Just leave the O/W and G/W pairs on the original jack and use the B/W and BN/W pairs for the second jack (remembering to punch them down on what would normally be the O/W and G/W pairs on that jack, of course).
