Intramodal Dispersion. Differences of Index of Refraction by wavelength. Learn more about a Refractive Index. See Index of Refraction for more information. The types are intramodal and intermodal dispersion. Intramodal, or chromatic, dispersion occurs in all types of fibers. Intermodal, or modal, dispersion occurs. Due to dispersion when the optical pulses travel along the fiber they broaden as shown in (1) Intra-modal or Chromatic dispersion (present in single mode an.
