Chromatic dispersion, английский
- Расширение светового импульса, вызванное разницей скоростей распространения волн различной длины, составляющих данный импульс (см. также коэффициент преломления)
- The frequency dependence of the phase velocity in a transparent medium
- Wavelength-dependent pulse spreading in optical fibers, measured in pico seconds (of pulse spreading) per nanometer (of source bandwidth) per kilometer (of fiber length). it is the sum of waveguide and material dispersion. reduced fiber bandwidth caused by different wavelengths of light traveling at different speeds down the optical fiber. chromatic dispersion occurs because the speed at which an optical pulse travels depends on its wavelength, a property inherent to all optical fiber. may be caused by material dispersion, waveguide dispersion, and profile dispersion.
