Which mechanism inhibits full signal propagation in optical fibers?

💡 Explanation

Stimulated Brillouin scattering generates a backward-propagating wave above a power threshold because optical phonons are excited due to light-matter interaction; therefore signal strength diminishes rather than being amplified or simply altered by dispersion.
