← ScienceWhich mechanism reduces clarity within fiber optic cables?
A)Modal dispersion causes signal blurring✓
B)Chromatic aberration creates color distortion
C)Fresnel reflection diminishes light intensity
D)Rayleigh scattering weakens transmission power
💡 Explanation
Signal blurring rises because multi-path interference causes modal dispersion between propagating light modes. It broadens pulses thereby reducing transmission clarity within fiber optic cables, therefore the clarity is reduced, rather than the others which are losses.
