Abstract
A method and system for identifying faults in a passive optical network (PON). The method comprises acquiring at an optical network terminal of the PON at least one parameter indicative of at least one malfunction in at least one optical network unit of the PON, and identifying each malfunction from the at least one parameter. The parameters measured include, for each ONU, laser power, sync-lock and -unlock time and bit error rates. The information at the OLT is acquired remotely and in digital form, without use of any physical probing of any point or element in the PON. The system includes a temporal measurement module and a power laser measurement module coupled to a central processing unit that can extract fault information from digital data processed in the two modules.
