← ScienceWhich outcome occurs when injecting incoherent electromagnetic pulses into optical fiber?
A)Reduced signal transmission distance✓
B)Increased stimulated Raman scattering
C)Enhanced four-wave mixing efficiency
D)Suppressed polarization-mode dispersion
💡 Explanation
Reduced signal transmission occurs because incoherent pulses lack consistent phase relationships, therefore destructive interference dominates rather than constructive, preventing long distance propagation of the guided wave induced by the fiber's waveguide.
