← ScienceWhich limit restricts data propagation in fiber optics?
A)Modal dispersion causes pulse broadening✓
B)Impedance mismatch creates signal reflection
C)Chromatic aberration causes image blurring
D)Fresnel Equations limit incident angles
💡 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.
