Diseño de una red de acceso de fibra óptica para proveer video e internet y evaluar el funcionamiento de la red en el sector de Huambaló.

Abstract

The aim of this study was to design a fiber-optic access network to provide video and data services, test the operation of the network in the Huambaló sector. This was done with a quantitative approach since surveys were taken as a starting point to collect information on the current state of the area and subsequently, the information gotten was tabulated. With the maps of the sector, a network was designed adapted to the standards of Optical Network with Gigabit Capacity (GPON). Advantages and disadvantages with the current network, some possible clients, the distance of the most distant and near the user, were analyzed. Based on these antecedents a map of a converging optical network with single-mode fiber was designed, which contains the networks: feeder, distribution, and dispersion. Using the OptiSystem software, the network was simulated with the two most critical cases testing the technical transmission parameters: attenuation, bit error rate (BER), and quality factor Q. The first case corresponds to the closest user 1.34 Km with minimum losses and maximum power, the second case to the farthest user 4.2 Km with maximum losses and minimum power of the OLT equipment. It was got: -17.43dBm and -22.57dBm in attenuation, 16.61 and 6.03 of Q factor and 2.57e^(-62) y 8.13e^(-10) of BER for the first and second case correspondingly, as a result, the values of both cases are within the ITU G.984.2 class C+, being the most optimal, since it has a greater margin of minimum and maximum sensitivity in the OLT as in the optical network terminal (ONT). It is recommended that the equipment to be used complies with the technical characteristics of the regulations for the correct operation of the network.
