OPTICAL TRANSMISSION METHOD AND OPTICAL TRANSMISSION SYSTEM
摘要
In this optical transmission method in which a plurality of channels are respectively wavelength multiplexed and transmitted, data transmitted on each of the wavelength-multiplexed channels is configured from inter-channel independent data areas and inter-channel non-independent data areas. The data patterns of the inter-channel non-independent data areas are set so as to be variable, and the time period at which polarized wave states between the plurality of channels correlate is shortened to reduce nonlinear optical effects generated between channels, and suppress deterioration in signal quality at the reception end.
