Abstract

In this paper, an integrated monitoring architecture base don telephone maintenance networks for the optical CATV networks is proposed for the first time. Part of the field trail result is also shown. The integrated monitoring system includes the element monitoring sub-system (EMS), the RF performance monitoring sub-system (PMS), and the fiber monitoring sub-system (FMS). The EMS can monitor the active devices, including the optical transmitters and optical receivers in optical CATV networks. The PMS can monitor the RF performance of carrier-to-noise ratio, composite second order, composite triple beat, and per channel RF power level. The FMS can monitor the state of the fiber, and locate the fault for the point-to-point and the passive branching fiber networks. Both polling and alarm call-back methods can be executed. All the polling instructions and monitoring data are transmitted through the telephone maintenance networks. These three sub-systems share the common platform based on NT operation system, and user can access these three sub-systems just from a terminal. This integrated monitoring system not only provides the surveillance function, but also offers the administration function with user-friendly interface.
