Yes there is a standard but there are also may non-standard implementations.
I was a little worried about the comment regarding "isolation" being
hard to implement. The standard for Ethernet required galvanic
isolation on all Ethernet ports by use of a transformer. So POE
simply buts a DC bias on the wire. I think it can provide 12 Watts of
power
