← ScienceWhich disruptive outcome occurs when multi-mode optical fiber junctions are misaligned?
A)Increased modal dispersion✓
B)Reduced stimulated emission
C)Enhanced Raman scattering
D)Higher refractive index
💡 Explanation
Increased modal dispersion occurs because mode interference causes differential path delays; therefore, signal broadens over distance, rather than enhanced scattering, because interference is destructive when phases vary randomly due to misalignment.
