As redes de acesso em fibra ótica têm sido consideradas uma solução definitiva para a necessidade constante de larguras de banda cada vez mais elevadas. Por essa razão, as redes PON (Passive Optical Network) têm tido um crescimento enorme nos últimos anos, oferecendo diversas soluções ao cliente final quer este seja residencial ou empresarial. No entanto, o projeto das redes de acesso é um processo complexo e demorado. Pretende-se com esta dissertação, o desenvolvimento de uma aplicação que, quando usada conjuntamente com o esquemático do projeto realizado no software AutoCad, realize, de uma forma automática, o levantamento dos equipamentos na célula projetada, o cálculo das atenuações, bem como o estudo tecno-económico da rede. Foram realizadas diversas simulações, para testar a viabilidade do software, para a análise da rede para o caso de existir apenas uma operadora, mas também numa situação em que duas operadoras a partilham a mesma infraestrutura. Em termos médios, e com suporte ao software desenvolvido, pode afirmar-se que o custo de implementação de uma célula ronda valores entre 250 000 e 300 000 €. Caso a rede seja projetada para uma operadora, e admitindo uma taxa de penetração de 70%, o tempo de retorno é inferior a dois anos. No caso da rede ser partilha entre operadoras, admitindo uma taxa de penetração da rede de 100%, o tempo de retorno passaria a ser quatorze meses para uma operadora e nove meses para outra, sendo estes valores dependentes da taxa de penetração dos serviços oferecidos.
Fiber optic access networks have been considered a definitive solution to the constant need for increasingly higher bandwidths. For this reason, PON (Passive Optical Network) networks have grown enormously in recent years, offering different solutions to the end customer, whether it is residential or business. However, the project of access networks is a complex and time-consuming process. It is intended with this dissertation, the design of an application that, when used together with the schematic of the project, carried out in AutoCAD software, performs the survey of the equipment in the projected cell, attenuation calculations, as well as the techno-economic study of the network. Simulations were carried out, to test the viability of the software, for an analysis of the network in case there is one or two operators sharing it. In average terms, and with the support of the developed software, it can be said that the cost of implementing a cell ranges from 250,000 to 300,000 €. If the network is designed for an operator, with a penetration rate of 70%, the turnaround time is less than two years. If the network is shared between operators, with a network penetration rate of 100%, the return time would be fourteen months for one operator and nine months for the other, being these values dependent on the penetration rate of the services offered.
