← ScienceWhich consequence results when signal reflections during long-distance fiber optic propagation increase beyond a threshold?
A)Reduced stimulated Brillouin scattering
B)Increased four-wave mixing efficiency
C)Signal power fading intensifies✓
D)Chromatic dispersion effects mitigate
💡 Explanation
Increased reflections create interference causing signal degradation, because constructive and destructive interference alters amplitudes due to the superposition principle–specifically Signal Power Fading. Therefore, increased fading is true, rather than Brillouin scattering reduction which requires specific optical powers.
