Which limitation arises in wavelength-division multiplexing (WDM) fiber optic systems using stimulated Raman scattering?

💡 Explanation

Channel power imbalances occur in WDM systems because the stimulated Raman scattering mechanism transfers power non-uniformly between channels. Therefore, shorter wavelengths lose power to longer ones, rather than channels maintaining equal power levels through the fiber span.
