Abstract
The present invention relates to a device for transmission by power-line communication () between two items of equipment () on board an aircraft (), comprising a transmission cable () configured to simultaneously transmit a power supply current and a data signal. This cable () comprises two twisted pairs of conductors (). The device comprises a data sender () comprising a COFDM coupler () configured to modulate a signal by carrier modulation according to a COFDM mode, and a data receiver () comprising a COFDM coupler () configured to demodulate a signal modulated by carrier modulation according to a COFDM mode. The data sender () is configured to send a test signal by carrier modulation according to a COFDM mode, while the data receiver () is configured to detect signals corresponding to the test signals sent, and to analyze the carriers of the detected signal in regard to the signal sent and deduce therefrom the state of the transmission cable ().
