← ScienceWhich optical distortion occurs when high-bandwidth signals propagate through optical fibers?
A)Intermodal dispersion interference broadens pulses✓
B)Chromatic aberration reduces signal clarity
C)Rayleigh scattering attenuates signal power
D)Fresnel reflection produces ghost signals
💡 Explanation
Intermodal dispersion occurs when light takes different paths, thus causing constructive and destructive interference. Because signals travel at varyingspeeds, broadending signal pulses are created across long distances rather than sharp arrival, therefore impacting data transmission.
