Abstract
A power line communication apparatus includes a first power line communication device disposed at a signal transmit end, a second power line communication device disposed at a signal receive end, a power line, a first magnetic ring disposed at the signal transmit end, and a second magnetic ring disposed at the signal receive end. The second power line communication device receives the modulated signal from the power line. The power line includes a wire for transmitting electric energy and a shield layer that wraps the wire for electromagnetic shielding. The wire and the shield layer separately extend from the signal transmit end to the signal receive end. The first magnetic ring and the second magnetic ring are separately coupled to the shield layer, to suppress inductance attenuation of the magnetic ring and improve reliability of the transmitted modulated signal.
