All ethernet ports are connected to center-tapped transformers, to isolate the noisy cable lines from the very sensitive integrated circuits of the ethernet controller chipset.
The interesting thing is that the center-tapped transformers used in gigabit ports can be used to extract phantom power from the ethernet data lines.
The Ubiquiti AirFiber 24Ghz uses the following standard:
(+) = Pair 1/2 & 4/5 = Orange & Blue pairs
(-) = Pair 3/6 & 7/8 = Green & Brown pairs
