In optical fiber communication carrying dense wavelength division multiplexing (DWDM) signals, which consequence relates to exceeding Raman scattering threshold?

💡 Explanation

Exceeding the Raman scattering threshold causes power transfer between wavelengths, producing channel crosstalk because high optical power induces non-linear effects. Since SBS is independent of Raman and velocity/dispersion are more direct effects, therefore increased crosstalk is the correct answer, rather than the others.
