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. Definition of Intramodal Dispersion. Intramodal Dispersion on The Free Dictionary The Timbercon Fiber Optic Glossary continues to expand and improve. There are two different types of dispersion in optical fibers. The types are intramodal and intermodal dispersion. Intramodal, or chromatic, dispersion occurs in all.
