针对无源光网络(PON)的传统监测方案存在的成本高、系统复杂,以及无法实现在线监测等问题,提出了一种改进的基于调频连续波的PON网络监测方案。采用VIP和Matlab协同仿真,研究了该方案对业务通信性能的影响,结果表明:调频连续波频率变化基本对下行业务信号无影响,调制指数越高对下行业务信号的影响越大,如果调制指数控制在0.05以内,则可忽略其对下行业务信号的影响。
Aiming at the problems of high cost, complex system and inability to realize on-line monitoring in traditional PON monitoring scheme, an improved PON network monitoring scheme based on FM continuous wave is proposed. The simulation results show that the frequency variation of the FM continuous wave has no effect on the downlink service signals. The higher the modulation index, the greater the impact on the downlink service signals. If the modulation index Control within 0.05, you can ignore the impact of the downlink traffic signal.
