FIBER OPTIC COMMUNICATIONS
personal.utdallas.eduTransmission over fiber is limited by the attenuation and dispersion. Multimode fibers may experience Multimode dispersion: The delayed rays cause pulse spreading Chromatic dispersion: Individual wavelengths may travel at different speeds. Dispersion creates an inherent operational limit defined as EE4367 Telecom.
