摘要： A method, device and system for automatically discovering optical fiber connection within a network element are provided. In the method, a destination board determines whether it is connected with a source single board for the first time according to a triple group message received within a predefined period and sent by the source single board, and if yes, sends a sextuple group message generated based on its triple group message to an ASON, and stores the sextuple group message in a local database; otherwise, it sends the sextuple group message stored in the local database and corresponding to the triple group message, to the ASON when timing is reached; when receiving the sextuple group message and determining that the sextuple group message is not stored locally, the ASON detects validity of a connection corresponding to the sextuple group message, and locally stores the sextuple group message if the connection is valid, otherwise, displays connection error information to a user.

摘要： Using the conventional OMCI-model for handling stacking of additional ONUs to a main ONU (Optical Network Unit) connected to an OLT (Optical Line Terminal) in a PON (Passive Optical Network), when the main ONU is not provided with any chassis with physical slots for insertion of the additional units. Instead, the main ONU is initialized to be provided with a virtual chassis that includes a number of temporary virtual cardholders for assigning to an unknown connected stacked ONU, and a number of non-temporary virtual cardholders for assigning to a known stacked connected ONU. From a management perspective, the virtual cardholder corresponds to a physical cardholder/slot according to the conventional OMCI-model.

摘要： A position in which an optical signal characteristic is compensated in an optical network can be chosen. An optical network equipment measures an optical signal characteristic for each wavelength, and notifies an optical network equipment on a communication path of an optical signal characteristic index and control necessity determination threshold. In an upstream portion of the communication path, the optical network equipment (a start point or the like of the communication path) that can compensate the optical signal characteristic for each wavelength determines the necessity to eliminate a deviation between wavelengths and the position to eliminate it, using the optical signal characteristic index and the control necessity determination threshold. The equipment determines a compensator to be controlled, and a compensation amount, based on the result, and commands an optical network equipment including the compensator to control the compensator, using a communication path establishment control protocol such as GMPLS-extended RSVP-TE.

摘要： A method for reducing energy consumption of a passive optical network includes optical network units of the network which infer their downstream queue status rather than being explicitly notified by an optical line terminal of the network. Based on the inferred queue status, the optical network units make their own sleep mode decisions without assistance from optical line terminal. Both downstream traffic inference and sleep decision making at the optical network units are based on common information possessed by optical line terminal and optical network units. Accordingly, the optical line terminal can accurately infer the status of each optical network unit if the sleep control scheme implemented at an optical network unit is known by the optical line terminal.
