Análisis técnico comparativo de las redes de acceso ng-pon1 versus ng-pon2.

Abstract

The purpose of this study is to establish a comparative technical analysis between the new generation optical access networks NG-PON1 and NG-PON2, whose purpose is to supply the growing demand for bandwidth in Internet access by end users. Chapter one is based on a compendium of introductory topics on optical technologies that also includes a brief historical overview of the developed PON standards up to the most recent PON technologies. In the second chapter, an analysis of the technical characteristics for NG-PON1 and NG-PON2 will be presented. This analysis will be based on the recommendations of the FSAN (Full-Service Access Network) standardized by the ITU (International Telecommunication Union) to establish the parameters that each technology maintains in terms of the physical layer (PMD: Physical Medium Dependent), transmission convergence layer (TC: Transmision Convergence) and the combinations of the ONU management and control interface (OMCI, ONT Management and control interface). In the third chapter, a synthesis and comparative analysis of technical parameters that define the performance of the optical communications system of each technology is established, such as: power budget, splitting level, transmission speed, link distance, spectral flexibility, communication techniques. data transport etc. In addition, scenarios will be proposed that will allow the migration and coexistence between new generation technologies NG-PON1 and NG-PON2 with the infrastructure inherited from GPON (Gigabit-Capable Passive Optical Network). Finally, will present a synthesis of the conclusions and recommendations obtained during the development of this work.
