Title: Performance Evaluation of Gigabit Passive Optical Network (Gpon) Access Technology
Author: Altahir, Hiba Altahir Alameen
Abstract: Optical fiber plays an important role in the revolution of communication technologies as one of the most powerful access technologies. Passive Optical Network (PON) is a point to multi point (P2MP) network where an optical line terminal (OLT) at the service provider distributes services to many customers per shared fiber line. Gigabit passive optical network (GPON) is one of Time Division Multiplexing (TDM) PON that consists of Optical Line Terminal (OLT) at the central office, Optical Distribution Unit (ODU) which is passive optical splitter for network connectivity and Optical Network Unit (ONU) that located at the user’s premises. This technology lowers network costs, energy consumption, and lower maintenance requirements. It also provides more bandwidth. This project evaluated GPON bidirectional transmission performance of 32 users by taking different values of transmitted power, fiber cable length and operating wavelengths with multiple scenarios for both upstream and downstream directions. System analyzed depending on values of Bit Error Rate (BER), Q factor and eye diagram from simulation results when using OptiSystem-Optiwave version7.0 software. Observed that power scenario’s affected most at both upstream and downstream results compared to distance’s and wavelength’s scenarios. The project objectives have been successfully met. Some limitations have been discovered in the project and were exposed, and also future suggested work for the project is stated.
