A technique is proposed for estimating the signal-to-noise ratio in fiber-optic transmission systems with spectral multiplexing, multiplexing of orthogonal and non-orthogonal channel subcarriers in the case of cross-channel interference due to four-wave mixing in the fiber. It is shown that it is possible to estimate the signal-to-noise ratio of a system with any number of sub-carriers of channels from the results of measurements of this ratio for a four-channel transmission system.
