Abstract(s)
O interesse pelas redes óticas tem crescido à medida que aumentam as necessidades dos consumidores disporem de uma crescente largura de banda, em virtude dos serviços serem tecnologicamente mais avançados. A exigência de cada vez maiores larguras de banda tem captado o interesse pelo desenvolvimento das redes óticas. O sucesso das redes óticas é visível por parte dos operadores de telecomunicações, pela oferta de diversas soluções desde o cliente residencial ao empresarial. Além disso, as empresas associadas à indústria de telecomunicações apercebem-se do enorme potencial de construírem redes óticas que permitem distribuir os dados mais longe e mais rápido do que alguma vez antes.
Atendendo ao crescente interesse das redes óticas, é importante o dimensionamento destas. Por isso são necessárias ferramentas de simulação para identificar atempadamente o comportamento da ligação ótica antes da sua implementação.
Nesta dissertação foi desenvolvida uma ferramenta de simulação, simples e robusta para estudo de ligações óticas ponto a ponto numa rede de telecomunicações. É formada por diversos blocos, como por exemplo, o emissor, o recetor, o amplificador e a fibra. O utilizador deve selecionar um desses blocos e posteriormente interligá-los de forma a estabelecer a ligação ótica pretendida. Depois de desenhar a ligação ótica é possível adicionar novos equipamentos ou eventualmente eliminá-los em caso de necessidade. Por último, o utilizador inicializa a simulação ao clicar no botão e no fim são produzidos os resultados através de ficheiros localizados na pasta “Value”. Os resultados produzidos permitem analisar as limitações da ligação ótica.
De acordo com os inputs introduzidos pelo utilizador são produzidos pela ferramenta os resultados da atenuação, dispersão e das penalidades de potência ao longo da ligação ótica, sendo comparado esses resultados com os conceitos teóricos. Assim, esta ferramenta é simples, robusta e apresenta ao utilizador os principais parâmetros que permitem avaliar o desempenho da rede.
Para o desenvolvimento da ferramenta foi utilizada o programa Matlab, pois trata-se de um software interativo de alta performance vocacionado para o cálculo numérico.
The interest in optical networks has grown as consumers need an increasing bandwidth, since the services are technologically more advanced. The demand for increasing bandwidth has captured the interest in the development of optical networks which success is visible by telecommunications operators, by offering different solutions from the residential customer to the business customer. In addition, companies associated with the telecommunications industry are realizing the enormous potential of building optical networks that allow them to distribute data further and faster than ever before. Considering the growing interest of optical networks, their dimensioning is important. Therefore, simulation tools are needed to identify the behaviour of the optical connection before its implementation. In this dissertation, a simple and robust simulation tool was developed to study point-to-point optical connections in a telecommunications network. It consists of several blocks, for example, the emitter, the receiver, the amplifier and the fiber. The user must select one of these blocks and then interconnect them in order to establish the desired optical connection. After designing the optical connection, it is possible to add new equipment or eventually eliminate it if necessary. Finally, the user starts the simulation by pushing on the button and in the end the results are produced through files located in the “Value” folder. The results produced allow to analyse the limitations of the optical connection. According to the inputs, the results produced are returned by the tool, which are compared with the theoretical concepts. This tool is simple, efficient and presents the user with the main parameters of an optical network. For the development of the tool, it was used the Matlab software, because it is a high performance interactive software dedicated to numerical calculation.
