← ScienceWhich effect diminishes in optical fiber when source coherence lessens?
A)Stimulated Brillouin scattering
B)Chromatic dispersion
C)Fiber nonlinearity threshold✓
D)Material attenuation reduction
💡 Explanation
Reduced source coherence raises fiber nonlinearity threshold because Inter-Modulation Distortion experiences lessened constructive interference as optical signals propagate. Therefore, threshold increases rather than dispersion increases under these conditions.
