The invention discloses a uniform network managing system and method with optical receivers built in an all-in-one machine, and relates to the field of optical receives for optical access networks. A head end device of the system is provided with a plurality of private network managing interfaces suitable for the different optical receivers. The optical receivers are connected with the head end device through the private network managing interfaces. Private protocols are configured between the head end device and the optical receivers and used for obtaining or configuring necessary network managing information of the optical receivers. All the optical receivers are provided with uniform MIBs with network management items. The head end device is used for obtaining and configuring the MIBs with the network management items of the optical receivers. The optical receivers are used for returning an inquiry and configuration result to the head end device. An NMS is used for uniformly managing the head end device and the optical receivers. By means of the uniform network managing system and method, the running states of modules such as the head end device and the optical receivers are monitored easily and conveniently in real time, the network failure diagnosis is facilitated, the network topology is simple, the system and method can be conveniently used by people, and the application range is wide.
