Master’s Thesis Discusses Comparative Analysis of Optical Communication Networks

A Master’s thesis in the Electrical Engineering Department at the University of Technology examined the “Study and Comparative Analysis of an Optical Communication Network Systems”. The research, conducted by student Fadheela Thaer Mahmood, proposed exploring beam divergence and the effects of wavelength range on free-space optical communication channels.

The study evaluated quality factors and bit error rates for a 13-kilometer distance using OptiSystem 2015 and an APD detector. It concluded that beam divergence significantly influences system performance, with the 1550 nm wavelength showing superior attenuation characteristics compared to 1310 nm and 850 nm. The thesis also analyzed weather effects and optical amplifier usage based on transmission distance.

The defense committee included Prof. Dr. Jasim Kazem Hamoud as chairman, along with Prof. Dr. Ali Mohidi Hamadi, Asst. Prof. Dr. Ashwaq Qasim Hamid, and supervisors Asst. Prof. Dr. Alaa Hussein Ali and Dr. Alaa Hussein Ali Haider.
