Maximum Distances for Power Sources
Multiple PoE Extenders can be connected every 100 meters to obtain greater distances.
The actual figures depend on operating conditions. The range is over 24AWG or heavier
Cat-5s or Cat-6 cable except where specified.
Examples for medium power PoE devices (that are PoE Class 2 or require less than 6W).

PoE+ switch
(802.3at, output voltage 50V)
30W mid-span
(802.3at, output voltage 50V)
Examples for full power PoE devices (that are PoE Class 0 or 3, or require less than 12W).
