CA 2716739

A PON extender disclosed herein includes: an optical amplifier, adapted to compensate optical power for PON signals in a downlink channel; an optical control switch, connected with an ONU and adapted to extract overhead information of the PON signals in the downlink channel, and select one channel of ONU uplink signals as output uplink channel PON signals according to the extracted overhead information; and a regenerating device, adapted to regenerate optical signals for the uplink channel PON signals output under control of the optical control switch. A system and a method for extending a PON are disclosed herein. Through the embodiments of the present invention, a new PON extender is provided for the PON, and therefore, the split ratio of the PON fulfills higher requirements.

L'invention porte sur un dispositif, un système et un procédé d'extension de réseau optique passif (PON). Le dispositif comprend un amplificateur optique pour effectuer une compensation de puissance optique pour les signaux PON dans le canal descendant ; un commutateur de commande optique destiné à être connecté à des unités de réseau optique (ONU) et extraire les informations auxiliaires de signaux PON dans le canal descendant, et sélectionner des signaux montants d'un trajet d'ONU en tant que signaux PON délivrés dans un canal montant sur la base des informations auxiliaires extraites ; un appareil de régénération pour régénérer les signaux PON dans le canal montant qui est délivré sous la commande du commutateur de commande optique afin de produire des signaux optiques.
