Abstract
The phenomenon of four-wave mixing that occurs in passive optical networks with wavelength-division multiplexing of channels has been studied.пResults of modeling the distribution of combination frequencies over the spectrum depending on the number and frequency interval between the channels are given. To suppress crosstalk between the channels at combination frequencies, it is proposed to divide the range into two bands and select a guard interval between them. The effect of combination frequencies on the signal transmission quality is considered as a function of the power level in the channels, frequency interval, and transmission length.
