Attenuation-limited fiber length based on power budget equation / Nor Najwa Ismail

This project is to identify the best fiber length between Optical Line Terminal (OLT)and Optical Network Unit (ONU) in Passive Optical Network (PON) architecture for tree topology with 64 users based on the power budget equation. Parameters such as the number of connectors, splices and splitters should be considered since it will affect the system performance. Besides that, the transmission rates and types of photodetector also need to be considered. The simulated analysis of power loss, Bit Error Rate (BER) and Quality Factor (Q factor) evaluates the improvement of the performance. The simulation results are obtained by using Opti system 7.0. The simulated results indicated the transmission rates 4.8Gbit/s with APD photodetector can be used for farthest fiber length.
