摘要

The Raman crosstalk in wavelength division multiplexing transmission systems is analysed in respect of modulation statistical property and dispersion walk-off effect. Both the mean nonlinear depletions/gains and crosstalk variances experienced by individual channels are found to be asymmetric for intensity-modulated systems. The asymmetry increases with the number of channels and input power.
