← ScienceWhich degradation results when resonant frequency interference exceeds bandwidth of optical fiber?
A)Modal dispersion limits data rate✓
B)Material fatigue increases fiber brittleness
C)Chromatic dispersion creates signal distortion
D)Rayleigh scattering decreases signal strength
💡 Explanation
Modal dispersion will limit the data because multiple modes arrive at different times due to differing path lengths traveling through the fiber. Therefore the signal degrades, rather than the fiber’s composition because resonant frequency influences wave propagation.
