OPTICAL FILTERS PERFORMANCE ANALYSIS WITH DISPERSION COMPENSATION.

Microwave Photonics systems (MWP) have great potential in latest areas, such as 5G networks, Radar, and Internet of things. In order to have low cost with high bandwidth and less complex Photonic solution, the signal transmission system and the data rate, at which transmission is required, need to be highly efficient, however the factors such as dispersion, losses and non-linearity of the system greatly restrict the performance of the system. Dispersion losses are major portion of all losses occuring in transmission. To compensate the dispersion losses, various technique such as optical delay lines, optical filters, Fiber Bragg gratings can be used in transmission circuit. Along with the dispersion compensation in the system, a right type of filter is also required to ensure right signals at receiving with minimum of losses in strength. This paper analyses different optical filters such as Gaussian, Butterworth, Bessel and Fabry Perot to improve overall system transmission performance and suggests using the dispersion compensation system to minimizes the dispersion losses. The parameters Q-factor, BER rate and Eye heights are compared with changes in fiber length and bandwidth to estimate the best optical filter performance range. Further to that, the paper analyses the different methodologies used to compensate the dispersion and proposes the optimal solution to reduce chromatic dispersion in transmission system.
