Patent

CA 2219006

A communication network and method is provided to communicate between a central office/head end and a plurality of end-units (EUs). A first transmission medium is connected between the central office and an intermediate node. A plurality of second transmission mediums are connected between the central office and a plurality of mini-fiber nodes. The intermediate node is also associated with each of the mini-fiber nodes such that an analog broadcast service may be sent over the first transmission medium to each of the mini-fiber nodes. Further, switched digital services and digital broadcast services are also sent over the second transmission mediums to each of the mini-fiber nodes. The mini-fiber nodes combine the signals and send the combined signals to a corresponding subset of EUs.

Réseau et méthode de communication permettant de communiquer entre un central/tête de ligne et un certain nombre d'unités terminales (EU). Un premier support de transmission est connecté entre le central et un noeud intermédiaire. Un certain nombre de deuxièmes supports de transmission sont connectés entre le central et plusieurs mini-noeuds optiques. Le noeud intermédiaire est également associé à chacun des mini-noeuds optiques de sorte qu'un service de radiodiffusion analogique peut être transmis sur le premier support de transmission vers chacun des mini-noeuds optiques. En outre, des services numériques commutés et des services de radiodiffusion numériques peuvent être transmis sur les deuxièmes supports de transmission vers chacun des mini-noeuds optiques. Les mini-noeuds optiques combinent les signaux puis les envoient à un sous-ensemble correspondant des EU.
