Which undesirable consequence arises when dispersion becomes excessive in single-mode fiber optic data transmission?

💡 Explanation

Excessive dispersion broadens optical pulses via chromatic dispersion, blurring the signal because different wavelengths travel at different speeds in silica. Therefore, the data becomes unreadable over long distances, rather than maintaining signal integrity benefiting efficiency.
