Which risk significantly increases when propagation velocity in a fiber optic cable exceeds design thresholds?

💡 Explanation

Increased light speed leads to increased chromatic dispersion, or pulse broadening, because different wavelengths propagate at different rates within the fiber. Therefore, signal fidelity will decline, rather than being maintained absent dispersion management techniques.
