Abstract

Ce dispositif de communication comprend un réseau de distribution hybride fibre optique/câble coaxial. Un centre distributeur assure la transmission en aval de la téléphonie et des données de contrôle sur une première largeur de bande du réseau de distribution hybride fibre optique/câble coaxial et la réception de la téléphonie et des données de contrôle en amont sur une seconde largeur de bande. Ce centre distributeur inclut un modem à porteuse multiple permettant de moduler les données de téléphonie en aval sur un grand nombre de porteuses orthogonales de la première largeur de bande de la fréquence, et de démoduler les données de téléphonie en amont modulées sur de multiples porteuses orthogonales de la seconde largeur de bande. Ce dispositif comprend des unités de service dont le fonctionnement est lié au réseau de distribution hybride fibre optique/câble coaxial pour la transmission en amont et la réception en aval des données de contrôle et de la téléphonie. Une méthode et un appareil permettant d'effectuer une transformation de Fourier rapide (TFR) sont également fournis.
