A method and system provide a unique communication and protocol between an optical line termination device and a plurality of optical network units sitting at different distances from the optical line termination device. The OLT determines the distances between it and each ONU (302) and then requests communications from the ONUs in ascending order from the nearest to farthest (306, 308). The OLT also determines a time delayed period between the nearest ONU and the farthest ONU and awaits that time delay period (312) before initiating subsequent ONU communication with the ONUs.
L'invention concerne un procédé et un système permettant d'obtenir une communication et un protocole uniques entre un dispositif de terminaison de ligne optique ou OLT (optical line termination) et plusieurs unités de réseau optique ou ONU (optical network unit) se trouvant à différentes distances du dispositif de terminaison de ligne optique. L'OLT détermine les distances entre celui-ci et chaque ONU (302), puis demande des communications provenant des ONU dans l'ordre ascendant, du plus proche au plus éloigné (306, 308). L'OLT détermine également un retard entre l'ONU la plus proche et l'ONU la plus éloignée, et laisse passer ce retard (312) avant de lancer la communication ONU suivante avec les ONU.
