A real-time optical network monitoring system named Smart Access Network _ Testing, Analyzing and Database (SANTAD) that combined remote controlling, centralized monitoring and troubleshooting, fault detection, optical switching as well as protection and restoration features is introduced for delivering high quality of services (QoS) for passive optical network (PON). The implementation of SANTAD in PON shows its contribution on obtains the high accuracy in detecting any occurrence of fault and addressing the failure location within 30 seconds. The main advantages of this work are to assists the network operators to manage the PON network system more efficiently, reduce hands on workload, minimize network downtime, and rapidly restore failed services when problems are detected and diagnosed.
