four-wave mixing

A phenomenon that occurs in WDM and DWDM systems when three closely spaced signal wavelengths near the zero-dispersion wavelength interact with each other, producing a fourth wavelength that interferes with the original signal. A moderate amount of dispersion can be designed into some systems to ensure that this effect does not take place.
