    Dispersion compensation schemes- a system perspective
    (2021) Derias, Nour El Houda; Ben cherif Ikhlef, Djelloul; Zitouni, A. (Supervisor)
    One of the main factors limiting the performance of WDM systems is dispersion. The use of dispersion compensation fiber (DCF) is the most commonly used dispersion compensation method in WDM systems. In this work, the performance WDM systems atfrequency of 193.1THz. with different dispersion compensation schemes using DCF (pre compensation, post compensation and symmetrical compensation techniques) are analysedin terms of BER and Q factor. As a first part of the simulation.In the next part, 4-Channel WDM system is designed and simulated. all channels were discussed as Q factors and eye diagrams dependent on change in different parameters, such as signal input power, bite rate, and variations of both DCF and SMF length each alone. once the simulation is presented without compensation, then DCF technique is added as dispersion compensators in different configurations. Finally, 8-Channel WDM system is designed and simulated and tested under a list of parameters signal input power, bit rate DCF and SMF lengths. The effect of all the previous parameters were studied on different channels then the obtained results are presented.
