摘要
PON ODN网络由于无源特性导致对其质量监控较为困难,并严重影响着PON业务的稳定运行。针对PON ODN网络质量问题,首先描述了影响PON ODN网络质量的几种可能因素,然后总结了PON ODN网络质量监控方法并对比了几种方法的应用场景,最后探讨了点到多点网络中光路诊断的工程应用。监控诊断方法只有和具体网络相结合,才能有效地实现业务质量提升和保障网络稳定。
Because of the passive characteristics, it is hard to monitor the quality in PON ODN networks. It also seriously threatens the PON service. It firstly summarizes several behaviors and possible causes of interference. Then several monitoring methods of PON ODN quality are introduced and different application scenarios are compared. Finally, engineering application of optical diagnosis in the P2MP network is discussed. Only when the monitoring and diagnosis methods are combined with the specific network, the service quality and network stability can be guaranteed.
