The inventive communication device for converting a baseband data signal to a baseband signal for a coaxial cable, comprises at least one first input terminal for receiving an incoming baseband data signal, at least a first output terminal for outputting an outgoing baseband data signal, a first input/output terminal for connecting to a coaxial cable for communication of a duplex signal, first rebalancing means for converting said incoming baseband data signal to a balanced input signal, subtraction means for subtracting the balanced input signal from the duplex signal to obtain a balanced output signal, second rebalancing means for converting the balanced output signal to said outgoing baseband data signal.
