Abstract: An Ethernet signal coupling device comprises: a primary side comprising TX+, TX−, RX+ and RX− signal terminals; a secondary side comprising TD+, TD−, RD+ and RD− signal terminals; a first transformer comprising a primary coil coupled to the TX+ signal terminal and the TX− signal terminal and a secondary coil coupled to the TD+ signal terminal and the TD− signal terminal; and a second transformer comprising a primary coil coupled to the RX+ signal terminal and the RX− signal terminal and a secondary coil coupled to the RD+ signal terminal and the RD− signal terminal. The primary coils of the first and second transformers are wound by triple insulated wires, or the secondary coils of the first and second transformers are wound by triple insulated wires.
