Which limit restricts data propagation in fiber optics?

💡 Explanation

Modal dispersion limits data rates, because different modes travel various distances through the fiber causing pulse broadening, therefore, the receiver cannot distinguish individual bits, rather than impedance affecting only signal power, because impedance only impacts signal throughput.
