Evaluating Characteristics of 2.5 Gbps GPON using Various Distance and Wavelength

Abstract

Abstract In this paper, a discussion has been made to analysis is the performance of a Gigabyte Passive Optical Network (GPON) receiver for various distances and wavelengths with a constant power equal to 5 dB in a system having four users on the transmitter side and four in the destination. We will measure the Q-factor for four wavelengths downlink Optical-receiver to decide which wavelength has the best performance and cover the longest distance. Among the two data format, we used Return to Zero (RZ) and Non-Return to Zero (NRZ). Then prove how RZ gives higher effectiveness in the contras to NRZ and longer distance to cover specialty the wavelength (1310) followed with (1270) that it could reach 60 km with Q-factor (7.48) and (6.77) respectively.
