  • dispersion The separation of a beam into its various wavelength components. In an optical fiber, dispersion occurs because the differing wavelengths propagate at differing speeds. Also called chromatic dispersion.
  • dispersion-flattened single-mode fiber A type of glass optical fiber that provides low pulse dispersion over a broad portion of the light spectrum and as a result can operate at 1300-nm and 1550-nm wavelengths simultaneously.
  • chromaticity The qualities of color associated with hue and saturation, but not brightness or lightness.
  • optical fiber A thin filament of drawn or extruded glass or plastic having a central core and a cladding of lower index material to promote total internal reflection (TIR). It may be used singly to transmit pulsed optical signals (communications fiber) or in...
