Long Distance POE
19/08/08 14:38
Today, in one of our municipal implementations we pushed the limit of power-over-ethernet (POE). Using a single, twisted pair CMX Cat 5E cable and high quality RJ45 connectors we were able to run 15 volts of POE through two walls and over a distance of 284.5ft.
A very impressive number indeed, especially with only 15 volts being injected. At the end of our low resistance cabling we experienced a loss of only 1.85 volts.
