Which outcome increases during optical fiber transmission under dispersion?

💡 Explanation

Pulse broadening increases due to group velocity dispersion, affecting **coherence** between the carrier and sidebands, because spectral components travel at varying speeds. Therefore, pulse width increases, blurring the signal rather than improved signal integrity under idealized signal conditions.
