Análisis comparativo de las técnicas de modulación DPSK y QPSK en una red GPON-FTTH mediante simulación en python.

Abstract

This paper presents the “Comparative analysis of DPSK and QPSK modulation techniques in a GPON-FTTH network using Python simulation”. The topic was proposed in order to demonstrate that it is not necessary to acquire a simulation tool, such as OptiSystem, instead the Python programming language and its OpticomPy library will be used, which allows simulating environments by optimizing communication network parameters and thus provide efficiency in data transmission. In chapter 1, the general description of the degree work is presented, among the most important topics are the definition of the research problem, the general objective, the specific objectives and the research methodology used. Chapter 2 presents the literature review of optical access networks, with their respective standards. In chapter 3, the design of simulation algorithms in Python is presented and a computational package called “OptiComPy”, which is widely used by optical communications researchers, is also used. Furthermore, the results obtained are graphically displayed and analyzed to evaluate the performance of the GPON-FTTH network and to properly choose the modulation format that best suits and shows robustness.
