The optical fibers are the backbone of communication industry and are vastly studied in terms of their materials and propagation properties. These are necessary to decide the signal strength that need to be input so as to retrieve it successfully at the destination end. Among the different properties, dispersion plays a vital role as it spreads the optical pulse as the signal propagates along the length of fiber resulting in the signal delay. This is due to influence of refractive index on wavelengths travelling along the signal. The present work summarizes the different types of dispersion in optical fiber with a special focus on Group Velocity Dispersion or Chromatic Dispersion. The different technologies of dispersion monitoring are also summarized.
