Abstract :With the development of technology in recent years, the need for low loss communication systems with high data rates has increased. In this context, optical communication systems promising high data rates are of great interest. Optical communication systems attract the attention of many sectors, from internet service providers to military communication system designers, with the possibility of communication at the speed of light. In this study, an active optical network operating in 220 THz frequency band is designed using Optisystem 14.0 simulation software. In this designed optical network, the effect of the filter type to be used in the low-pass filter unit, which is used in the end user units and plays a major role in the correct demodulation of the message signals reaching the receiver unit, on the Q factor and eye diagram, which are key parameters in determining the data transmission quality, has been investigated. In this context, performance analysis of Chebyshev, Bessel, Butterworth, Gaussian low-pass filters in active optical networks has been made. According to the results obtained as a result of experimental studies, a Q factor value of 32.1471 was observed in the use of Gaussian low-pass filter in the receiver unit. While the most efficient filter type in the designed system is Gaussian low-pass filter, the filter type with the lowest efficiency has been determined as the Chebyshev filter.
