Which outcome occurs when a fiber optic cable suffers microbend deformation?

💡 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.
