Abstract

"SISTEMA DE COMUNICAçãO óPTICO, E, PROCESSO PARA OTIMIZAçãO DO DESEMPENHO DE UM SISTEMA DE COMUNICAçãO óPTICO WDM". Um sistema de comunicação óptico (1) compreendendo: um primeiro aparelho para suprir pelo menos três sinais ópticos, cada um possuindo um comprimento de onda predeterminado selecionado a partir de uma primeira faixa de comprimentos de onda <30><sym>; uma linha de transmissão óptica (1000), conectada opticamente ao dito primeiro aparelho, para a transmissão dos ditos pelo menos três sinais ópticos, a dita linha de transmissão óptica (1000) compreendendo por sua vez; i. pelo menos um sistema de amplificação óptica (11) possuindo um espectro de ganho predeterminado que, na dita primeira faixa comprimentos de onda <30><sym>, possui um máximo e um mínimo de ganho (expressos em dB), a diferença entre o dito máximo e o dito mínimo de ganho sendo <30>G~ tot~; e ii. pelo menos um filtro (100), associado ao dito pelo menos um sistema de amplificação óptica (11), e capaz de alternar a energia dos ditos pelo menos três sinais ópticos de acordo com uma curva de atenuação predeterminada como uma função do comprimento de onda, a dita curva de atenuação possuindo, na dita primeira faixa de comprimentos de onda <30>L; e um segundo aparelho para receber os ditos pelo menos três sinais ópticos caracterizado pelo fato da dita energia dos ditos pelo menos três sinais ópticos ser associada com uma pré ênfase pré selecionada e o dito <30>L ser pelo menos 0,5 dB maior do que o dito <30>G~ tot~.
