Concepts and Fundamental Theories of Optical Fibre Dispersions

In optical communication, there are different types of distortion that cause the received optical pulse shape to deform in irregular manner. This distortion which is mainly due to dispersion could degrade the phase of light wave signal and reduce the capacity in digital networks. Multimode fibre and single-mode fibre inherently lead to broadening of pulse, which is caused by three basic forms of fibre dispersion, namely, intermodal, chromatic and polarization-mode dispersions, respectively.
