A power line communication (PLC) signal pass-through device is disclosed. The PLC signal pass-through device includes a PLC adaptor; and a PLC signal transmission line, coupled to the PLC adaptor. The PLC signal transmission line includes a plurality of data wires, the data wires are grouped into a plurality of twist pairs, and the twist pairs transmit a plurality of data streams, respectively. The PLC signal transmission line between the PLC adaptor and the modem includes 4 data wires which are grouped into two twist pairs, and each twist pair transmits a data stream, respectively. Therefore, the PLC signal transmission line may transmit more data streams for improving the transmission efficiency. Besides, because each of the twist pairs is protected by the respective protection element, signals transmitted on the twist pairs may be not seriously interfered or influenced. |
