Evaluación de la técnica de modulación DPSK en sistemas DWDM de 40 Gbps para transmisión de largas distancias con esquemas de compensación de dispersión.

Abstract

This document presents the development of the degree work called “Evaluation of the DPSK modulation technique in 40 Gbps DWDM systems for long distance transmission with dispersion compensation schemes”. The first chapter describes the research work in which the problem, justification, general and specific objectives are defined. The second chapter presents the theoretical foundations of optical communications systems, types of modulations and multiplexing. Chapter 3 presents the research development aimed at evaluating the differential phase shift keying (DPSK) modulation technique in a passive optical network (PON) based on dense wavelength division multiplexing (DWDM) systems with a transmission capacity of 40 Gbps for long distance links. The performance of the proposed system was evaluated in terms of the quality factor Q and bit error rate (BER), progressively increasing the transmission distance to cover larger areas.
