I've never done it, but UBNT has some gigabit 24V A+B POE injectors for
AirFiber.  You should just be able to split it out on both sides so A POE
powers one and B POE powers the other.  If the topside devices cant take
power on the data pins, you would need to pick the power off with gigabit
power taps and put it back onto the power pins.  Much (1000X) easier to
just use a Netonxi 6 min in one of their little plastic od enclosures.
