Abstract
"SISTEMA DE TRANSMISSãO óPTICA, PROCESSO PARA A TRANSMISSãO DE SINAIS óPTICOS, E, UNIDADE DE AMPLIFICAçãO óPTICA". Uma unidade de amplificação óptica (100; 100') para amplificar os sinais ópticos em um sistema de transmissão óptica possui uma banda de comprimento de onda de amplificação com um limite de comprimento de onda inferior superior a 1570 nm e inclui uma entrada (101) para a entrada dos sinais ópticos, uma saída (102) para a saida dos sinais ópticos e um amplificador óptico (104) intercalado entre a entrada (101) e a saída (102) para amplificar os sinais ópticos. O amplificador óptico (104) incluir uma fibra de amplificação (108) co-envernizada com érbio e itérbio, pelo menos uma fonte de bomba (109, 110) para gerar a radiação de bomba e pelo menos um acoplador óptico (111, 112) acoplando opticamente as fontes de bomba (109, 110) à fibra de amplificação (108). A unidade de amplificação óptica possui um ganho de energia de pelo menos 31 dB quando os sinais ópticos possuem uma energia de entrada de pelo menos 10.5 dBm e comprimentos de onda dentro da banda de comprimento de onda de amplificação."OPTICAL TRANSMISSION SYSTEM, PROCESS FOR THE TRANSMISSION OF OPTICAL SIGNALS, AND, OPTICAL AMPLIFICATION UNIT". An optical amplification unit (100; 100 ') for amplifying optical signals in an optical transmission system has an amplification wavelength band with a wavelength limit of less than 1570 nm and includes an input (101) for the input of the optical signals, an output (102) for the output of the optical signals and an optical amplifier (104) between the input (101) and the output (102) to amplify the optical signals. The optical amplifier (104) includes an amplification fiber (108) co-varnished with erbium and ytterbium, at least one pump source (109, 110) to generate the pump radiation and at least one optical coupler (111, 112) optically coupling the pump sources (109, 110) to the amplification fiber (108). The optical amplification unit has an energy gain of at least 31 dB when the optical signals have an input energy of at least 10.5 dBm and wavelengths within the amplification wavelength band.
