Maximum PoE 802.3af distance 15.4W

I've got a new wiring project coming up shortly that may tax the limits of cat5e standards.

I am having trouble locating documentation that says what a theoretical maximum distance for a 802.3af class 3 device will be.

Has anyone run into problems with voltage loss over long distances? Will I be OK as long as the wire passes a fluke cat5e test?

Hi JP,

The standard 100m ethernet rules (90m drop + 10m patch/cross connect) still apply here. If the cables fall within this standard and pass the testing with good results you should be good to go.

Hope this helps!
