In this paper a performance analysis of passive optical networks (PONs) topologies is proposed. A powerful software design tool “OptiSystem” is used to analyze the performance and compare between two types of PONs topologies which are tree or star topology and bus topology. The performance analysis and comparison is performed in terms of communication distance, Q-factor, and bit error rate (BER) for each network topology. The proposed results are important to determine the maximum communication distances that can be reached by each topology with certain network parameters.
