← ScienceWhich outcome occurs when a fiber optic cable suffers microbend deformation?
A)Increased intermodal dispersion occurs✓
B)Polarization mode dispersion increases
C)Chromatic aberration distortion decreases
D)Refractive index contrast is amplified
💡 Explanation
Microbends introduce imperfections that cause constructive and destructive interference, thus increasing intermodal dispersion; because the modes interfere, the signal degrades, therefore increased dispersion rather than constant polarization or decreases in refraction.
