  • Bidirectional optical fiber auto-notifier test system
    Patent number: 10432302
    Abstract: Optical fiber communication systems include monitor filters that permit OTDR or other monitoring signals to co-propagate or counter-propagate on link fibers. OTDR measurements are periodically triggered, and acquired OTDR signatures are compared with store signatures to locate faults. The monitor filter can be used in single direction, dual OTDR bidirectional, or signal OTDR bidirectional (loopback) monitoring.
