Method for realizing optical network unit (ONU) redundancy protection in fiber to the home (FTTH) network, apparatus and system thereof

一种ftth网络中实现onu冗余保护的方法、装置及系统

Abstract

本发明提供一种FTTH网络中实现ONU冗余保护的方法、装置及系统,该系统包括OLT、光分路器和与每个用户连接的主用ONU和备用ONU,当OLT接收到设备告警时,判断设备告警类型是否为触发ONU保护切换的设备告警类型,当该设备告警类型为触发ONU保护切换的设备告警类型时,则打开备用ONU的UNI,通过备用ONU的UNI胃用户提供业务服务。由于在本发明中在用户侧设置有主用ONU和备用ONU,因此,当用户侧ONU出现问题时,可以切换到备用状态,保证业务的实现和恢复,从而提高了业务的安全性和可靠性。
The invention provides a method for realizing optical network unit (ONU) redundancy protection in a fiber to the home (FTTH) network, an apparatus and a system thereof. The system comprises: an optical line terminal (OLT), an optical splitter, primary ONUs and standby ONUs, wherein the primary ONUs and the standby ONUs are connected with each user. When receiving an equipment alarm, the OLT determines whether the type of the equipment alarm is the type of triggering ONU protection switching. When the type of the equipment alarm is the type of triggering ONU protection switching, an UNI of the standby ONUs is opened. Business services can be provided for the user through the UNI of the standby ONUs. In the invention, the primary ONUs and the standby ONUs are arranged on a user side. When the ONU of the user side goes wrong, a standby state can be switched into, realization and recovery of the service can be guaranteed. Therefore, security and reliability of the service can be raised.
