Which impairment arises when multiple wavelengths combine in a fiber optic cable, surpassing the optical power threshold?

💡 Explanation

Four-wave mixing interference becomes significant at high optical powers because it is a third-order nonlinear effect whereby multiple wavelengths interact creating new frequencies. Therefore, signal distortion increases rather than simpler effects caused by single wavelength interactions or waveguide imperfections.
