Abstract: The present invention discloses a method, device and system for managing information of an optical node in an optical distribution network, relates to management of information of an optical node in an optical distribution network, is capable of solving the problem of manual entry of information of an optical node being cumbersome, and is not limited by installation locations of the optical node. The method for managing information of an optical node in an optical distribution network includes: obtaining an identity code of an optical node; querying a pre-established optical node information table according to the identity code of the optical node, wherein the optical node information table comprises the identity code of the optical node and the installation location information of the optical node. The present invention is suitable for management of information of an optical node in an optical distribution network.

Abstract: An optical element module, an optical node, an optical distribution system, and a management method are disclosed. The optical element module includes: at least one passive optical element, at least one fiber adapter, a power interface, and a state detecting unit, where the passive optical element is configured to distribute and/or process an optical signal that can proceed even without power supply; the fiber adapter is configured to connect a fiber connector and provide a fiber port to couple a fiber; the power interface is connected to a power cable or a power bus and configured to feed power from the power cable or power bus to the state detecting unit; and the state detecting unit, if powered, is configured to respond to a connection state change of the fiber in the fiber adapter and output a state indication that indicates the state of the fiber port.

Abstract: The present invention relates to a system and a method for handling link failure of broadband access devices in the field of communication technology. Said system for handling link failure of broadband access devices installs a status monitoring module and a failure handling module, which are used to monitor the working status of the uplink for a broadband access device and provide clients accessing said device with an emergency communication channel by enabling IP layer functions or the Internet layer-2 interoperability functions of the Ethernet when said link is interrupted. The present invention solves the problem of legacy broadband access devices being unable to provide emergency communication channels for clients accessing said broadband access device in case the connection between said broadband access device and its upper layer network fails.
