Hoje em dia, existe a percepção de que as novas redes de acesso em fibra óptica conseguem fornecer capacidades ilimitadas; contudo a realidade é diferente, e os aspectos práticos de implementação, as opções arquitecturais e de desempenho de equipamentos de rede levam quase sempre a uma capacidade limitada, embora bastante superior à actualmente disponível pelas redes de cobre. Sendo assim é fundamental continuar a procura de novas soluções que permitam superar estas questões. Neste trabalho é apresentado um estudo das redes de nova geração em termos das opções existentes para combater as limitações actuais, bem como as tendências para os próximos anos, onde se enquadram as redes ópticas coerentes, que são vistas como uma forte possibilidade para cumprir os requisitos de NG-PON2.
Nowadays, there is the perception that new optical fiber access networks can provide unlimited capabilities, but the reality is different. The practicalities of implementation, the architectural options and performance of network equipment almost always lead to a limited capacity. However, optical fiber networks have much greater capacity than the existing copper networks. Therefore it is essential to continue the search for new solutions to address these issues. To make this possible, is presented here a study of next generation networks in terms of options to tackle the current constraints, and to obtain a direction for the upcoming years, where they fit coherent optical networks, which are seen as a strong possibility to fulfil NG-PON2 requirements.
