OK, so we’re trying to figure out why CAT-5 cable requires a centric and linear layout (one twisted pair is split outside the center twisted pair, the outer pairs are laid out in linear fashion) into an RJ-45 connector and they can’t just be inserted linearly, most specifically for PoE runs. I’m guessing it has something to do with the magnetic field of each twist but I can’t find anything definite. Anyone know the reason behind the inclusion of a centric layout for the center two twisted pairs?
