Devido à sua importância, tais redes necessitam constantemente de supervisão. Diversas técnicas vêm sendo empregadas para supervisão de redes ópticas, dentre as quais se destacam as que utilizam reflectometria, pois agregam vantagens, tais como: baixo custo, em comparação com outros métodos de supervisão, e não exigência de intervenção na casa do usuário. Esta dissertação apresenta uma estratégia capaz de quantificar, por meio de simulações, o impacto que a técnica de reflectometria no domínio do tempo gera como interferência em transmissões típicas de uma rede WDM-PON. / Passive Optical Networks are increasingly diffused as a broadband access technology. Due to their importance, such networks demands continue supervision scheme. Different techniques could be employed for Optical Network Supervision, among them those using reflectometry have highlighted, because it offer low cost when compared with other monitoring methods and do not require intervention in the user’s home. On the other hand, when doing monitoring, it is expected that this action does not influence the information signal transmitted to the subscriber. In this context, this work aims to quantify, through simulations, how the technique of time domain optical reflectometry interferes on the transmission of a WDM-PON network.
