传统的信道状态监测方法采用离线测试的形式,增加监测延迟量,不能及时反映信道状态.因此,文章设计光时域反射仪(Optical Time Domain Reflectometer,OTDR)下的无源光网络通信信道状态监测方法.利用OTDR接收监测信号,缩短监测的时延,并对监测数据进行抗干扰处理,以便准确反映通信信道的状态.一旦发现信道状态异常,就发出安全预警.实验结果表明,该方法对于6个样本监测延迟的最大值仅为0.47 ms,稳定性较好.
Research on Intelligent Monitoring Method of Passive Optical Networks Channel State under OTDR
The traditional channel state monitoring method adopts offline testing,which increases the monitoring delay and cannot reflect the channel state in a timely manner.Therefore,the article proposes a passive optical network communication channel state monitoring method using an Optical Time Domain Reflectometer(OTDR).Using OTDR to receive monitoring signals,reducing monitoring latency,and performing anti-interference processing on monitoring data to accurately reflect the status of the communication channel.Once an abnormal channel status is detected,a security warning will be issued.The experimental results show that the maximum monitoring delay of this method for 6 samples is only 0.47 ms,indicating good stability.
