Title (EN) ETHERNET COMMUNICATION DEVICE ON COAXIAL CABLE
(FR) DISPOSITIF DE COMMUNICATION ETHERNET SUR CABLE COAXIAL
Abstract:
(EN) 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 (3a) for receiving an incoming baseband data signal, - at least a first output terminal (3b) for outputting an outgoing baseband data signal, - a first input/output terminal (20) for connecting to a coaxial cable (18) for communication of a duplex signal, - first rebalancing means (21) for converting said incoming baseband data signal to a balanced input signal, - subtraction means (27, 29, 31) for subtracting the balanced input signal from the duplex signal to obtain a balanced output signal, - second rebalancing means (23) for converting the balanced output signal to said outgoing baseband data signal.
(FR) La présente invention concerne un dispositif de communication qui permet de convertir un signal de données de bande de base en un signal de bande de base pour câble coaxial, lequel dispositif comprend: au moins un premier terminal d'entrée (3a) qui reçoit un signal de données de bande de base entrant; au moins un premier terminal de sortie (3b) qui sort un signal de données de bande de base sortant; un premier terminal d'entrée/sortie (20) qui est relié à un câble coaxial (18) afin de communiquer un signal duplex; de premiers moyens de rééquilibrage (21) qui convertissent ledit signal de données de bande de base entrant en un signal d'entrée équilibré; des moyens de soustraction (27, 29, 31) qui soustraient le signal d'entrée équilibré du signal duplex afin d'obtenir un signal de sortie équilibré; de seconds moyens de rééquilibrage (23) qui convertissent le signal de sortie équilibré en signal de données de bande de base sortant.
