Simulation and Analysis of Chromatic Dispersion in Finite-Length Single-Mode Optical Fibres for Efficient Signal Transmission

Abstract: Dispersion is an important design parameter in optical fiber communication systems because it severely limits the maximum transmission distance and data rate due to pulse broadening and Inter-Symbol Interference (ISI). This work is a simulation of the effect of chromatic dispersion on the performance of single mode optical fiber based on LIGHTSIM simulation tool. The simulation examines the relationship between pulse spreading, fiber length, source spectral width and the resulting dispersion-limited length. The results highlight the importance of efficient dispersion control techniques to improve the transmission reach and overall system performance. These results can be very useful for the design and optimization of long-distance, high-speed optical communication networks.
