Diseño y simulación de una red de acceso con tecnología ITU G987.X para la parroquia de Zámbiza en la cuidad de Quito.

Abstract

This study aimed to design and simulate an access network with ITU G987.X technology for Zambiza parish in Quito city to improve internet services through theoretical foundations and characteristics of access networks study and G987.X (XG-PON) standard passive optical networks' evolution study. First, the potential demand was determined by applying a survey to the parish inhabitants, both in residential and commercial areas. Then, based on the results obtained, the capacity required to cover the needs of the network's current efficiency and future subscribers was estimated and calculated. In addition, the equipment that meets the technical parameters to operate with the XG-PON technology was determined, and an equitable location was established by layout. Moreover, a referential budget was prepared for the technological implementation costs. Finally, a simulation of the network scheme was carried out using the OptiSystem software to check the operation of the passive elements of the network and the optical fiber. It was possible to verify the optimal functioning of the network and the quality of the signal transmitted in it based on the results obtained in the calculations and the simulations. Consequently, the simulation graphs show that the quality of the communication system signal will not suffer significant degradations that affect the proposed design when there are changes or growth in the network. It is recommended to use the ITU-T G987 most current publications regulations because they are still under development the same as the review of corrections in previous standards and the compatibility parameters.
