    How the system works

    the test access modules, the OTDR, and the optical reflectors onto the PON system.

    The OTDR
    scans the distribution lines to detect reflection at the reflectors with no intererence to the service.

    When the line breaks
    the reflection at the ONU can not reach to the OTDR.

    The system operator
    can identify from the remote office whether the cause of the failure is a line breakage or a device failure.
