Fiber to the home technology

Abstract

RESUMEN: El presente Trabajo Fin de Grado tiene como objetivo profundizar y consolidar conocimientos sobre sistemas de comunicaciones ópticos, más concretamente redes de fibra óptica hasta el hogar. El trabajo se estructura en cuatro bloques. En el primero, se desarrollarán los fundamentos y características principales de la fibra, así como los distintos tipos que se emplean en este tipo de redes. Concluyendo que, actualmente es el único medio de transmisión capaz de abastecer la demanda creciente de ancho de banda. Lo cual, nos muestra la importancia que tiene en la actualidad y sobre todo de cara al futuro. En el segundo bloque profundizaremos en la arquitectura de redes FTTH, basadas en la tecnología GPON, es decir, empleando elementos pasivos. Explicaremos en que consiste la multiplexación de longitudes de onda, tan importante en estos sistemas de telecomunicación, permitiendo el flujo de datos de los canales de subida y de bajada entre OLT y ONT a través del mismo medio de transmisión (fibras bidireccionales). En el tercer capítulo describimos los elementos que componen una red óptica, con el splitter como dispositivo estrella de este tipo de redes, permitiendo compartir el mismo cable en el tramo de aproximación desde la central telefónica a los usuarios, reduciendo así considerablemente los gastos. Por último, nos centraremos en aspectos relevantes a la hora de diseñar una red, diferenciando entre diversas áreas de actuación, que determinará el tipo de arquitectura empleada, así como los tendidos del cableado más adecuados. Diseñar una red, como cualquier proyecto de ingeniería, consiste en hacerlo de la manera más eficiente posible, tratando de dar el mejor servicio al menor coste, por lo que siempre, se tenderá a utilizar infraestructura existente para reducir los enormes costes de inversión que suponen estas redes. En cualquier caso, es necesario realizar un buen estudio de mercado para reducir riesgos, y este entre otras cosas, nos indica que en el futuro cercano los sistemas de comunicaciones se basarán en FTTH, por lo que, tenemos que considerar siempre la posibilidad de que la red vaya a crecer, y anticiparnos a ello, dejándola preparada para posibles ampliaciones futuras. Este aspecto es principalmente el que determina a las redes arboladas generalmente como la mejor opción, debido a su flexibilidad.

ABSTRACT: The purpose of this Bachelor’s thesis is to deepen and to consolidate knowledge about optical communication systems, in particular, fiber-optic networks to the home. The work is divided in four blocks. In the first one the fundamentals and main characteristics of the fiber optic are explained. Additionally, It is also described the different types of fiber used in this type of networks, getting to the conclusion that fiber optic is currently the only transmission medium capable of satisfying the growing demand in broadband. This fact shows us the present and future importance of the fiber optic. In the second block we will get into the architecture of FTTH networks, based on GPON technology, that is, the ones using passive elements. We will explain what is the multiplexing of wavelengths, a technique of high importance in these telecommunication systems because allows the data flow of the up and down channels between OLT and ONT by the same transmission medium (bidirectional fibers). In the third chapter we will describe the elements that form an optical network, with the splitter as the essential device of this type of networks since allows the cable sharing in the approaching section from the telephone exchange to the users, thus considerably reducing expenses. Finally, we will focus on relevant aspects when designing a network. We will distinguish among the different areas of action which determine the type of architecture used, as well as the most appropriate wiring lines. Designing a network, like any other engineering project, must be done in the most efficient way possible, trying to give the best service at the lowest cost. So whenever it is possible, the existing infrastructure should be used to reduce the enormous costs of investment these networks imply. Anyway, it is necessary to conduct a good market study to reduce risks. The market study of this thesis indicates, among other things, that in the near future communication systems will be based on FTTH, so we must always consider the possibility that the network grows, and we must anticipate to this fact by preparing the network for possible extensions. This aspect mainly determines the tree networks as the best option in general due to its flexibility.
