Four pair CAT4, (yes, there was a CAT4) CAT5 and CAT5e was being made way before POE came into use. Still POE is only an extra one pair. Gigabit requires CAT6 and all four pair.

You need the 4 pairs so you can steal two of them for the phone and the fax machine.

Well, that actually may be the reason and BICSI and other butt head IT "authorities" wouldn't hear of it. But I kind of like my idea that the whole thing is BS from the cable manufacturers to get more money out of your pockets. Otherwise they would make 2 pair CAT5e.
