Abstract

Esta solicitud proporciona un método de negociación de longitud de onda de una red óptica pasiva de longitud de onda múltiple, que incluye: recibir una tabla de estatus de longitud de onda que es difundida por una OLT a través de cada canal de longitud de onda de enlace descendente de un sistema de PON de longitud de onda múltiple, donde la tabla de estatus de longitud de onda se utiliza para indicar información acerca de las longitudes de onda disponibles del sistema de PON de longitud de onda múltiple y la información estadística de las ONUs registradas de un canal de longitud de onda correspondiente; seleccionar una longitud de onda de transmisión de enlace ascendente y una longitud de onda de recepción de enlace descendente de acuerdo con la tabla de estatus de longitud de onda; y reportar la información acerca de la longitud de onda de transmisión de enlace ascendente y la información acerca de la longitud de onda de recepción de enlace descendente a la OLT de tal forma que la OLT actualiza la tabla de estatus de longitud de onda. Esta solicitud también proporciona un aparato de negociación de longitud de onda de la red óptica pasiva de longitud de onda múltiple y un sistema de red óptica pasiva de longitud de onda múltiple.
