ABSTRACT:
A device including an element for receiving an electrical signal comprising a high-frequency data signal component and a low-frequency power supply component. The electrical signal is conveyed in an electrical cable of an electrical installation. The device further includes impedance matching operative in a band of frequencies of the high-frequency signal component, the impedance matching being determined as a function of one or more characteristics of the electrical cable. Such a device can be integrated into a socket outlet or an electrical device or take the form of a socket adaptor.
