Abstract

Patente de Invenção: "MéTODOS, SISTEMAS E APARELHOS DE PROTEçãO óPTICA". Os sistemas ópticos da presente invenção incluem pelo menos um amplificador óptico configurado para fornecer uma amplificação dividida ao longo da faixa de comprimentos de onda de sinal que carregam as informações entre os nodos de processamento de sinais ópticos. O amplificador óptico está configurado para dividir o ganho fornecido para uma pluralidade de grupos de comprimento de onda de tal modo que o ganho em um grupo de comprimento de onda é somente parcialmente interdependente, ou independente, do ganho nos outros grupos de comprimento de onda. O sistema óptico está ainda configurado para transmitir as informações utilizando os comprimentos de onda de trabalho e um ou mais comprimentos de onda de proteção em diferentes grupos de comprimento de onda. As informações podem ser transmitidas simultaneamente para proporcionar uma proteção do tipo 1+N de fibra única. Similarmente, as informações podem ser chaveadas do primeiro comprimento de onda para o segundo comprimento de onda quando de uma falha para fornecer uma proteção do tipo M:N de fibra única. Este esquema de proteção pode ser utilizado em ambos os sistemas uni e bidirecional para fornecer uma proteção para informações que estão sendo transmitidas sobre uma ou mais fibras ou percursos de fibra.
