Abstract

"SISTEMAS DE COMUNICAçãO E DE AMPLIFICAçãO óPTICA E PROCESSO PARA FORNECER UM SINAL DE BOMBA A LASER EM UM SISTEMA DE COMUNICAçãO óPTICA". Melhoramento na confiabilidade de um sistema de comunicação óptica compreendendo duas linhas de fibra óptica, um primeiro transmissor para transmitir pelo menos um sinal da primeira linha óptica, um segundo transmissor para transmitir pelo menos um sinal na segunda linha óptica, pelo menos um amplificador de dois estágios em cada uma das citadas primeira e segunda linha, bombas a laser provendo sinais de bombeamento para os citados estágios dos amplificadores, um primeiro receptor para receber o sinal da primeira linha óptica, e um segundo receptor para receber o sinal da segunda linha óptica, no qual as citadas bombas a laser formam um sistema único que provê um primeiro sinal de bombeamento para pelo menos um estágio de pelo menos um citado amplificador de cada uma das citadas primeira e segunda linha."COMMUNICATION AND OPTICAL AMPLIFICATION SYSTEMS AND PROCESS TO PROVIDE A LASER PUMP SIGNAL IN AN OPTICAL COMMUNICATION SYSTEM". Improvement in the reliability of an optical communication system comprising two optical fiber lines, a first transmitter to transmit at least one signal from the first optical line, a second transmitter to transmit at least one signal on the second optical line, at least one amplifier of two stages in each of the aforementioned first and second lines, laser pumps providing pumping signals for said amplifier stages, a first receiver to receive the signal from the first optical line, and a second receiver to receive the signal from the second optical line, in which the aforementioned laser pumps form a unique system that provides a first pumping signal for at least one stage of at least one said amplifier for each of the aforementioned first and second lines.
