WebThe transmission of information along optical fibers is normally achieved by sending out a sequence of pulses of light energy. However, as an individual pulse propagates, it spreads out, due to the dispersive properties of the fiber. Clearly if this spread becomes sufficiently large the pulse will overlap with adjacent pulses, leading to a ... WebGraded Index Fibres: The refractive index of the optical fibre decreases as the radial distance from the fibre axis increases. The classification based on the materials used is as follows: Plastic Optical Fibres: The polymethylmethacrylate is used as a core material for the transmission of light.
