波長分割多重伝送における、種々の変調符号に対する最適な単一伝送速度を計算機シミュレーションにより評価した。最適な単一伝送速度は変調符号によらず、25Gbps~40Gbpsであった。また、最適な単一平均信号電力はOdBm~2dBmであった。%Characteristics of wavelength division multiplexing transmission systems were numerically analyzed to estimate optimal capacity per channel for several modulation formats. The optimal capacity per channel were found to be between 25Gbps/ch and 40Gbps/ch in each format. The optimal average power were found to be between OdBm and 2dBm in each format.
