Zusammenfassung:	A SYSTEM (100) AND METHOD FOR DIAGNOSING FAULTS IN A LONG-REACH PASSIVE OPTICAL NETWORK (LR-PON) HAS BEEN DISCLOSED. THE SYSTEM (100) COMPRISES AT LEAST ONE OPTICAL LINE TERMINAL, OLT (104) PLACED AT A CENTRAL OFFICE NODE (CO) OF A SERVICE PROVIDER, THE OLT (104) COMMUNICABLY COUPLED TO A PLURALITY OF OPTICAL NETWORK UNITS, ONUs (112) THROUGH AT LEAST ONE OPTICAL DISTRIBUTION NETWORK, ODN AND AT LEAST ONE OPTICAL FIBER PHYSICAL LINK. THE SYSTEM (100) FURTHER INCLUDES AT LEAST ONE NETWORK MANAGEMENT UNIT, NMU (114) TO MEASURE AT LEAST ONE PERFORMANCE PARAMETER OF THE LR-PON, AT LEAST ONE OPTICAL AMPLIFIER (106); AND A DIAGNOSTIC UNIT (102) COMMUNICABLY CONNECTED TO THE OLT (104) AND THE NMU (114), CONFIGURED TO RECEIVE AT LEAST ONE PERFORMANCE PARAMETERS FROM THE NMU (114); ANALYZE PERFORMANCE TREND OF THE AT LEAST ONE PARAMETER; AND NOTIFY THE NOC (104) IF A FAULT IS DIAGNOSED IN THE LR-PON.
