What Voltage Is A Poe Switch

The standard POE power supply voltage is set to 48V. The power supply voltage ranges from 44 to 57V. If the voltage on the supply side is not enough, or if the voltage is 40V, the transmission distance of the data signal will be greatly reduced, maybe only 30 or 40 meters.
Since the use of POE power supply is definitely for convenience and the transmission distance is expected to be longer, the power supply voltage should not be too low.
