摘要

针对双模ONU（光网络单元）注册前如何正确识别当前系统的问题

提出了两种双模ONU的切换方法

结合双模ONU可能出现的切换情况

选择适合当前切换场景的切换方法

设计并实现了双模ONU自动识别当前GPON（吉比特无源光网络）/EPON（以太无源光网络）系统的方案

从而解决了运营商采用混合方式部署接入系统的问题

同时也为实现两种技术的融合提供了参考。

Abstract

For correct identification of current systems prior to dual-mode ONU registration

this paper presents two switching methods.In relation to the possible switching conditions for dual-mode ONU

it selects a switching method appropriate for the current switching scenario and designs and realizes an ONU automatical identification for current GPON/EPON systems

fascilitating hybrid deployment of access systems and providing an option for the convergence of the two technologies.
