In single-mode fiber only intramodal dispersion exists
Modal dispersion does not exist in single mode fibers. Single mode fibers also exhibit the highest possible bandwidth. The intermodal dispersion results due to propagation delay difference between various. In fiber-optic communication, an intramodal dispersion, is a category of dispersion that occurs within a single mode optical fiber. Since this phenomenon is wavelength dependent and group velocity is a function of wavelength, it is also called as group velocity dispersion (GVD). This causes different spectral components to propagate along an optical fiber with different group velocities.

Application of Optical Circulators in Dispersion Compensation
Dispersion compensation is achieved in an optical communications system by using an optical circulator with first, second, and third ports. The first and third ports are connected to system optical fibers. This grating is made so that faster wavelengths are reflected at the far end of the filter (therefore experiencing a. The 'optocirculator' commonly known as optical circulator is the circulator which is majorly used for optical communication. Normally, dispersion in fiber optic cable includes modal dispersion, chromatic dispersion and polarization mode dispersion.
