Abstract: This invention provides an active solution for the problem of remote power feeding on only one pair of communication wires. The invention is an active system of one power transmitter and one or more power receivers. Unlike mains power distribution networks, in this invention, both power transmitter and power receivers maintain low impedance in the power pass band frequencies and high impedance in other communication bands with a sharp slop of impedance transition between bands. This behavior allows a parallel connection of the transmitters and receivers to an existing communication line with a negligible loading of communication signals. The system can be implemented with any type of pair of wires: twisted pair, parallel pair, coax etc.
