摘要： When a signal of weak optical power is received immediately after a signal of intense optical power, input of the signal of intense optical power readily causes saturation, and the influence interferes in the signal of weak optical power to deteriorate receiver sensitivity. Moreover, when a reverse-bias voltage of APD is changed, if a difference between the voltages is large, a next optical signal is received until the receiver sensitivity of the APD becomes stable, so that receiver sensitivity deteriorates. A DBA order is determined so that a difference in reverse-bias voltage is small, and reverse-bias voltage is controlled in line with reception timing from ONU.

摘要： A general object of the present invention is to provide an optical communication system in which an optical transmission power of an optical communication apparatus is controlled to be a required minimum power that apparatuses of all subscribers in the optical communication system meet a prescribed error rate. An optical line terminating apparatus (OLT) transmits data to multiple optical network apparatuses (ONUs) at an optical intensity calculated based on information acquired from the multiple ONUs, which is related to optical intensities of signals that the multiple ONUs receive from the OLT, the optical intensity being calculated so that a minimum optical intensity of the optical intensities of the signals is greater than a predetermined value.

摘要： The present invention provides a network in which the installation of working lines may be enabled based on the required traffic and the high speed switching of the transmission lines may be realized, as well as a transmission equipment used for that network and a method of control thereof. The transmission equipment comprises an APS byte transmitter/receiver for exchanging information on failures with adjacent transmission equipment through a protection line, a monitor for monitoring anomalies on a plurality of the working lines, a Network Table for storing data indicating network structure, a processing unit for determining working lines to be switched based on the data stored in the Network Table and for processing APS bytes. APS bytes are allocated with the working line number, its priority, and the source node number of switching signal. In addition a Network Table is provided to each node for storing connecting state of the network and information on failures, thereby the destination node may be identified. When a failure occurs, the best optimal line switching will be performed by exchanging information on failures by means of the APS bytes.
