When it comes to PoE transmission distance, it is necessary to understand the key factors that determine the distance. In fact, using standard Ethernet cable (twisted pair) to transmit DC power can transmit far, which is far greater than the transmission distance of data signals. Therefore, the distance of data transmission is the key.
