Procedimento prático para a elaboração de uma rede GPON FTTH balanceada

Abstract

Introduction: Communication systems based on coaxial metallic cables reached close to their theoretical limit of transmission, accelerating research related to fiber optics, since the requirement for bandwidth by the users made the metallic communication systems obsolete. For this reason, telecommunications company are seeking to focus their investments on the deployment of optical fiber (FO) networks, as they provide increased opportunities for service offerings, greater reliability, and significantly lower operating expenses. Gigabit Passive Optical Network (GPON) technology is the most used in access networks that are based on FTTX (Fiber To The X = Home, Building, Curb, etc.) concepts to deliver tripleplay services (data, voice and video) to subscribers using FO from the provider to the clients' properties. Goals: The objective of the work is to design a balanced GPON FTTH system to serve a city located in Piauí Brazil, thus providing guiding subsidies to those who need to work with this type of project. In addition, it aims to demonstrate the steps for the elaboration of a balanced GPON FTTH project, characterize the basic elements that make up a passive network and analyze the economic viability of the proposed study. Methodology: The study is divided in 6 chapters, the first of which places the reader on motivation and goals. In the second one the light and the equipment that compose the optical network is conceptualized, in the third it is exposed on the different types of network, focusing on the passive ones. In the fourth is debated about attenuation and measurement equipment. The fifth chapter is the case study carried out and in the sixth is presenting the result and the conclusion obtained. Results: It believed that the work fulfilled the objectives presented because a practical procedure for the elaboration of a balanced GPON FTTH network was described. It was possible to verify that in the elaboration of the FTTH network it is necessary to know the location in which the system will be installed, to trace the service regions, the positioning of the CTOs and CEOs, the path of the backbone and the distances between the equipments. Considerations: In addition, it can be verified that the financial return to the provider that uses optical network is short, mainly because the demand is great, the system is safe, the transmission can be realized at great distances without use of active elements, characteristics that make the economically viable system against traditional active networks.
