Estudio de factibilidad y diseño de una red HFC con estándar DOCSIS 3.1 para proveer servicios triple-play en el sector La Joya de la ciudad Ambato.

Abstract

In this project, a study was carried out on the feasibility of designing a Hybrid Fiber and Coaxial (HFC) network with a Docsis version 3.1 standard in order to provide Triple-Play services for the La Joya sector located in Ambato, To achieve the objective, the investigation of the operation of an HFC network from the headend to the end user was carried out, the topologies that are used in each section and the material that is used as the optical fiber and the coaxial cable in each subnetwork, the transformation of information from optical signals to electrical signals, as well as the Docsis standards that allow transmitting speeds of up to 10 GHz for downloading and 1 GHz for uploading information and finally the compatible equipment that supports these parameters, to verify the viability, a survey was carried out on a sample of 327 users from a population universe of 1,765 homes, in which it was found that 85.15% of users preferred a new network provider because the costs are currently high and in Hybrid networks installation and maintenance costs are reduced, maintaining high speeds. In addition, a reference budget was prepared for the costs of network implementation and its annual maintenance. Finally, the simulation of the network was carried out on the OptiSystem Software in which it was verified that the results obtained are similar to those calculated in the test of the most distant and closest user, allowing to corroborate the correct operation of the network by the power received and by means of the Eye diagram showed that the signal did not suffer considerable degradation. It is recommended to investigate each stage of the HFC network to avoid omitting elements in the power calculation, giving way to obtaining erroneous results.
