Abstract:
1. An optical transmission system comprising: an optical transmission path to transmit WDM signals to which optical signals of different wavelengths are multiplexed, the WDM signals including optical signals of different bit rates or optical signals of different modulation formats; a repeater arranged in the optical transmission path, the repeater including a chromatic dispersion compensation unit to compensate chromatic dispersion for the WDM signals; and a network management system including processes of: wherein the network management system variably sets the dispersion compensation ratio in order to be a maximum value of a product of a transmission capacity of the transmission path and a transmission distance of the transmission line, wherein the maximum value is determined on the basis of a range to satisfy a spec of the transmission distance or the transmission capacity for one or more optical signals multiplexed in the WDM signals to be transmitted.
