Abstract

Las realizaciones de la presente describen un método y aparato para detectar una ONU y un sistema de redes ópticas pasivas. El método incluye: detectar un código de identidad de una ONU en una ventana vacía de enlace de subida abierto o una ranura de tiempo vacía y determinar que una ONU que corresponde al código de identidad de la ONU es una ONU furtiva de acuerdo con el código de identidad de la ONU. También se presentan un aparato y sistema de redes ópticas pasivas correspondientes en las realizaciones de la presente. En el sistema de redes ópticas pasivas, se detecta y determina una ONU furtiva de manera rápida y eficiente y se reduce el efecto sobre un servicio de enlace de subida.
