For the limitations of vibration signals caused by non-stationary autoregressive (AR) model which can not effectively describe the signal characteristics, it is presented a fault diagnosis based on autoregressive conditional heteroskedasticity (ARCH) model. This method firstly uses ARCH model to fit various fault signals and regard the proceeds of the model parameters as the characteristics of fault...
We propose a novel in-service fault localization scheme combined and monitored simultaneously. Fiber fault and automatic protection switching in ONUs are monitored in real-time at central office (CO) without interrupting customer service.
