what is dispersion in optical fiber
Chromatic dispersion is a phenomenon that is an important factor in fiber optic communications. It is the result of the different colors, or wavelengths, in a light beam arriving at their destination at slightly different times.The result is a spreading, or dispersion, of the on-off light pulses that convey digital information.t is the result of the different colors, or wavelengths, in a light beam arriving at their destination at slightly different times.
