Embodiment 1
[0039] figure 1 is a schematic diagram of the network architecture of the present invention, and the embodiment of the present application can run on figure 1 On the network architecture shown, the system of the present invention also includes: EMS100, OLT200, ODN300, ONU400, wherein,
[0040] EMS100 is used for configuration, management and maintenance of OLT200 and EPON network; EMS network management maintains and manages historical information of OLT200 and ONU400 as well as related alarm and notification messages. And can complete the judgment and location of specific abnormal information according to relevant alarm and notification messages;
[0041] OLT200, manages and controls ONU400, completes the registration and authentication of ONU400 when the optical path quality is normal, and completes the data forwarding;
[0042] ODN300 is used to connect different numbers of ONU400 under OLT200, as a direct physical connection channel between OLT200 and ONU400, with PON po...
