Remotely Control, Centralized Monitoring and Failure Analyzing in PON

This paper presented a centralized monitoring and failure analyzing approach for passive optical network (PON) using Smart Access Network Testing, Analyzing and Database (SANTAD). SANTAD is developed for downwardly monitoring and failure detection in PON from central office (CO) towards customer premises. SANTAD interfaced with optical time domain reflectometer (OTDR) test module via Ethernet connection for remotely control and operate from CO. SANTAD accumulated every OTDR measurement to be displayed on a single computer screen for centralized monitoring and further data analyzing. SANTAD enable each status of customer premise equipment (CPE) connected line to be displayed a single screen with capability to configure the attenuation and detect the failure simultaneously. The analysis results and information will be delivered to the field engineers for promptly actions. This paper also discussed the uses of laser as optical source in optical fiber communication system as well as the eye safety issues with laser. Key words: SANTAD, downwardly monitoring, failure detection, OTDR, data analyzing
