← ScienceWhich outcome results when mismatched fiber optic cables form an air gap?
A)Increased signal phase interference✓
B)Signal frequency bandwidth broadening
C)Reduced modal dispersion effects
D)Enhanced stimulated Raman scattering
💡 Explanation
Increased signal phase interference occurs because of Fabry-Pérot interference. Reflections at the air-glass interfaces within the gap create interfering waves. Therefore, increased interference reduces light transmission, rather than alternatives like scattering that occur due to impurities within the material.
