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。
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, fas- cilitating hybrid deployment of access systems and providing an option for the convergence of the two technologies.
