Which risk increases when unpolarized signals enter fiber optics?

💡 Explanation

Polarization mode dispersion increases because random polarizations entering a fiber experience different refractive indices leading to varying propagation speeds; therefore the signal broadens, rather than amplification or frequency effects happening with stimulated scattering.
