In fiber-optic communications, wavelength-division multiplexing (WDM) is a technology which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths (i.e., colors) of laser light. This technique enables bidirectional communications over a single strand of fiber (also called wavelength-division duplexing) as well as multiplication of capacity.
To explain the coherent crosstalk due to FWM, we can consider that a single FWM product is created at the same wavelength as the signal channel fi. Assuming that the power of the FWM
