Which outcome occurs when a pulsed electromagnetic wave experiences wave dispersion within a fiber optic cable?

💡 Explanation

Pulse width broadens due to wave dispersion, a phenomenon where different frequency components of the pulse travel at slightly different speeds. Therefore, the pulse spreads out in time, rather than signal amplitude increasing, because dispersion separates frequencies.
