Design and Development of GUI for the Mitigation of Chromatic Dispersion: A New Approach
Sukkur IBA Journal of Emerging Technologies, 2022 Chromatic Dispersion (CD) is the important effect that is considering for optical communication system design as it broadens the pulse during the propagation along channel resulting in pulse overlapping and ultimately bit errors raises. The increment in
