Diseño de una ODN para una red óptica de acceso mediante tecnología GPON para servicios triple play en el sector “La Tolita 1 y La Tolita 2” de la ciudad de Esmeraldas.

Abstract

The purpose of the following research is to design an ODN for an access optical network through GPON technology for triple play services in “La Tolita 1 and La Tolita 2” area from Esmeraldas. The principal GPON access technological characteristics were analyzed as well as the ODN infrastructure description. Some real and concrete data of the population were obtained to make statistical graphics and charts which allowed making the analysis and interpretation of results for each questions, this reflected the prospective demand to the fulfilled; this is 536 users representing 67% of the population studied. On the other hand the possible price accepted by the users to contract the service is 30 dollars. Then the proposal design in AUTOCAD was presented taking into account the technical criteria. For example FTTN as the most efficient architecture in this case, tree-type topology, the existing OLT location which belongs to CNT public company. In order to validate the design, it was necessary to apply Optisystem 7.0 software to analyze the BER(Bit Error Rate) through the eye pattern, since it is the main indicator which guaranties the optic fiber link quality. Finally the economic analysis was presented and the viability of the project was determined. The project has an investment of 90277,10 dollars, which according to the projections will be recovered within six months. It is concluded that GPON networks support 2.4Gbit/s downstream direction nominal rates and 1.2 Gbits/s upstream as well as the ODN maximum length; it is to say that the distance between the OLT and ONT must not exceed 20 km. For this it is recommended to respect the design norms for GPON network which will allow obtaining excellent results.
