Stacked passive optical network

Abstract

A crescente procura por serviços de banda larga, e diversificação de conteúdos e serviços disponibilizados pela rede tem contribuído fortemente para o que se designa “last mile bottleneck”. Como solução surgiram as redes óticas de acesso passivas, que oferecem elevada largura de banda e uma relação preço por número de clientes servidos muito competitiva. Ao longo deste documento são estudadas as redes passivas de acesso que atualmente têm maior taxa de implementação, EPON e GPON e é proposto um cenário de convivência entre as duas utilizando a mesma fibra de distribuição. Para implementação do cenário proposto, foi estudada e avaliada separadamente a convivência no sentido ONUOLT e OLT-ONU. Na comunicação ONU-OLT a viabilidade estatística da convivência foi comprovada através de simulação e seguidamente corroboração experimental. Na comunicação OLT-ONU diversos mecanismos de conversão de comprimento de onda exclusivamente óticos como modulação de ganho e fase cruzada, e rotação cruzada de polarização, foram avaliados por simulação e comprovados em laboratório.

The increasing demand for broadband services and the diversification of content and services provided by the network has strongly contributed for the so-called "last mile bottleneck". As a solution, the passive optical networks (PON) emerged, offering high bandwidth and a very competitive cost per number of customers served. Throughout this document are studied the passive access networks that currently experience higher deployment rates, EPON and GPON and a coexistence scenario over the same distribution fiber is proposed. To implement the proposed scenario and due to incompatibility between the two referred standards, upstream and downstream communication directions were studied and evaluated separately. For upstream communication the statistical viability of the network was assessed using simulation and experimental corroboration. In the downstream communication several mechanisms for all-optical wavelength conversion such as cross gain and phase modulation, and also cross polarization rotation were evaluated and tested.
