Please refer to FIG. 1 , which is a schematic structural diagram of a PoE system (Power over Ethernet system, hereinafter referred to as a PoE system). The PoE system includes a Power Supply Equipment (PSE) 110 and a Powered Device (PD) 120, which are connected to each other through a network route (described by the RJ-45 specification). The equipment is in compliance with the IEEE-802.3 specification. The network route has eight wires, wherein the first and second pins of the mesh route are used by the network power supply device 110 to transmit data to the network power receiving device 120, and the third and sixth pins of the network route are used by the network power receiving device 120 to transmit data. To the network power supply device 110. The network power supply device 110 includes a power supply module 111 and two transmission transformers 112. The two transmission transformers 112 are disposed at the transmission end (the first and second wirings) and the receiving end of the network power supply device 110 (the third and sixth wirings). The power supply module 111 is connected to the two transmission transformers 112 and provides a power signal to the central portion of the induction coil of the transmission transformer 112 to transmit the power signal to the network power receiving device 120 in a manner that does not hinder data transmission.
