AN OPTICAL ASSEMBLYMODULE, OPTICAL NODE, OPTICAL DISTRIBUTION SYSTEM AND THE MANAGEMENT METHOD THEREOF

摘要

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. With such architecture, the present invention helps to reduce electromagnetic interference and power consumption, and facilitates state management.
