Abstract

"SISTEMA DE TELECOMUNICAçãO óPTICO, E, PROCESSO PARA TRANSMITIR SINAIS óPTICOS". Trata-se de um sistema de telecomunicação, que compreende: - uma estação transmissora capaz de emitir um sinal óptico com uma potência de entre 18 a 30 dBm; - uma linha de transmissão de fibra óptica capaz de transmitir o sinal óptico, que compreende uma fibra deslocada por dispersão com um comprimento de entre 100 Km e 1000 Km'; - uma estação receptora óptica, capaz de receber o sinal óptico; o qual compreende, entre a linha de transmissão e o receptor óptico, um compensador de dispersão cromática. De preferência, a linha de transmissão de fibra óptica tem um comprimento de entre 200 e 400 Km.
