Abstract :
We propose to reduce intrachannel four-wave mixing by using subchannel multiplexing for each wavelength-division-multiplexed channel. We calculate the growth in both signal distortion and noise, and we show that there is a tradeoff between propagation distance and spectral efficiency. The method performs best with strong dispersion management and Raman amplification.
