In a hybrid fiber coax (HFC) cable system (20), data is communicated upstream from user terminals (100) to a headend (240) of the system (20) to realize various interactive services. The user terminals (100) generate analog modulated signals representing the user data, which populate different channels in a reverse passband of the system. In accordance with the invention, the analog modulated signals are transformed to the corresponding digital baseband signals containing the data. The resulting digital baseband signals are optically transmitted to the headend (240), thereby efficiently utilizing the limited capacity of the fiber optical portion of the HFC cable system (20).

Dans un système à câble hybride fibre-coaxial (HFC), les données sont communiquées vers l'amont de terminaux utilisateur à une tête du système pour la réalisation de différents services interactifs. Les terminaux utilisateur produisent des signaux analogiques modulés représentant les données utilisateur, lesdits signaux alimentant différents canaux dans une bande passante inverse du système. Selon l'invention, les signaux analogiques modulés sont convertis en signaux numériques de bande de base correspondants, contenant les données. Les signaux numériques de bande de base obtenus sont transmis par voie optique à la tête du système, ce qui permet une utilisation efficace de la capacité limitée de la partie fibre optique du système à câble HFC.
