摘要： A residual chromatic dispersion target value at a terminal node is set for each wavelength path, and also, candidates of a dispersion compensation amount settable in each chromatic dispersion compensation module on an optical network are set, and further, computation processing is executed for selecting the dispersion compensation amount in each chromatic dispersion compensation module from the candidates so that the sum of errors between the residual chromatic dispersion amounts and the set residual chromatic dispersion target values at the terminal nodes for all of wavelength paths becomes minimum. As a result, for each wavelength path on the optical network, the dispersion compensation amount in each chromatic dispersion compensation module can be designed in optimum so as to satisfy the desired optical signal quality at the terminal node, while considering the residual chromatic dispersion during the transmission.

摘要： A communication system that improves operation and maintenance and controls communication efficiently. A supervisory signal sending control section controls the sending of a supervisory signal for having supervisory control of optical communication and a drive supervisory signal for controlling the driving of an optical fiber amplifier for performing optical amplification by using a non-linear optical phenomenon in an optical fiber. A sending stop section receives a stop signal and stops the sending of the drive supervisory signal. A drive control section receives the drive supervisory signal and controls the driving of the optical fiber amplifier. A stop signal sending section sends the stop signal to a sending unit after the optical fiber amplifier being driven.
