  • Detection system for identifying faults in passive optical networks
    Patent number: 7800744
    Abstract: A detection system that performs in a passive optical network is disclosed. The detection system uses a central office to provide detection signals to corresponding fiber branches for obtaining different reflected signals based on different optical network models. Hence, the central office can determine whether fiber branches in the passive optical network has a fault and where the fault is according to the reflected signals.
    Type: Grant
