1. A method of correcting faults in a passive optical network (PON), comprising:

  • transmitting a communications signal including a bit error rate (BER) test data pattern via an optical communications path from a first optical network node to a second optical network node in a passive optical network;

    acquiring from the second optical network node a status indicator representative of an operating state at the second optical network node responsive to the test pattern;

    determining if a fault condition exists as a function of the status indicator; and

    performing an action to correct the fault condition in an event a fault condition exists.
