Abstract
An apparatus for retrieving data from an optical wavelength-division multiplexing (WDM) signal received via a WDM path in a wavelength-division multiplexing transmission system having a plurality of channels associated with different wavelengths, comprises a demultiplexer configured to split the optical WDM signal into a plurality of signals each associated with one of the channels. A calculator configured to calculate data associated with a respective one of the channels based on the signal associated with the respective channel and taking information on determined crosstalk interferences of other channels to the respective channel into consideration. A transmitter for transmitting an optical WDM signal via a WDM path in a WDM transmission system having a plurality of channels associated with different wavelengths, comprises a predistorter configured to predistort data associated with a respective one of the channels by information on determined crosstalk interferences of other channels to the respective channel and a signal source for each channel of the WDM transmission system configured to convert the data associated with the respective channel into an optical signal having a carrier frequency corresponding to the wavelength of the respective channel and to transmit the optical signal through the WDM path.
