Abstract
A power line communication system includes a power distribution device connected to two power lines, a plurality of power line communication devices and a first coupler device electrically connected between the first power line and the second power line. The first coupler device is configured at the last end of the power line communication system. Before a transmitting device transmits data to a receiving device, the first coupler device determines whether to couple the power lines with each other according a first signal quality between the transmitting and the receiving device when the power lines are not coupled with each other and a second signal quality between the transmitting and the receiving device when the power lines are coupled with each other.
