摘要： An optical transceiver apparatus includes a gain medium, a photoelectric converter, at least one AWG, and a partial reflection mirror. The at least one AWG includes two common ports and multiple branch ports. One of the two common ports functions as a signal sending port, and the other functions as a signal receiving port, where bandwidth of the signal sending port is less than that of the signal receiving port. The gain medium and the photoelectric converter are connected to one of the branch ports of the AWG. The AWG and the partial reflection mirror are configured to cooperatively perform wavelength self-injection locking on an optical signal provided by the gain medium, and output the optical signal through the signal sending port. The AWG is further configured to demultiplex an optical signal received by the signal receiving port to a branch port. A WDM-PON system is also provided.

摘要： The present disclosure discloses a method for managing user information in an instant messaging system in order to address the problems of increasing system workload, increasing network overhead and deteriorated system performance in existing technologies due to frequent access of user information management server or servers when user information is searched. According to a disclosed method, an access server obtains and stores information of contacts of a logged-in user; the access server notifies user information of the logged-in user to other access servers; the access servers that receive the notification store the user information of the logged-in user upon determining that contact(s) is/are found locally therein; and when the access server needs to obtain the information of the contacts of the user, the access server performs a search either locally or in other access servers. Furthermore, a communication system is also provided. The disclosed method and system are believed to result in greatly reduced frequency of searching user information in the user information management servers, reduced workload of the user information management servers, improved performance of searching user information and reduced network overhead of the system.
