Estudio y diseño de una red de planta externa de fibra óptica GPON para proveer servicios de voz, video y datos aplicado a la ciudad de Alausí para la CNT Empresa Pública Riobamba.

Abstract

This research is intended to study and design an access network to the GPON (Gigabytes Passive Optic) technology external plant in Alausí, to improve the National Telecommunication Corporation (NTC) services there. It accounts for a real need of Alausí population in regarding the results of a survey applied to locals which was addressed to assess the population’s acceptance of the GPON access network. The GPON access network design and implementation criteria lay not only on the International Telecommunication Union (UIT) standards and recommendations but also on the National Legislation for Telecommunication Corporation and the its institutional norms. The fiber optic cable type to be used for the feeder network and for the distribution network design is the G.652D and for the dispersion network design is the G.657A1 (Drop). The optic line terminal (OLT) was set in the Alausí central station, which will supply an existent service demand of 1257 local users as well as a service projected demand of 1350 local users. The study results also embrace the presupposed optic calculus for the linkage minimal and maximum distance which accounts for 23, 15 dB and 22, 92 dB respectively. On the other hand, the economic cost analysis for both the feeder network and for the distribution network design was carried out accounting for $ 42505, 66 in this section the project cost-benefit analysis was also detailed, which reveals that the investment can be recovered by CNT in a term of 6 months. This study proposal design reaches the nominal downstream speed taxes of 2, 4 Gigabytes and upstream speed taxes of 1,2 Gigabytes. Therefore, it is advisable that National Telecommunication Corporation (NTC) considers the GPON access network design of this study for a forward implementation in Alausí city.
