Dispersion Analysis in Single Mode and Multimode Fiber

Abstract

A cylindrical-shaped dielectric waveguide is what an optical fibre is. The core cladding interface confines electromagnetic energy in the form of light within its surface and directs light through a number of internal reflections if the angle of incidence is larger than the critical angle c. The dispersion of the transmitted optical signal causes distortion in both digital and analogue transmission across optical fibres. When optical fibre transmission is widely employed and some sort of digital modulation is applied, dispersion mechanisms inside the fibre cause the transmitted light pulses to broaden as they move along the channel.
