Abstract

dispositivo de derivação com função de oadm e sistema de rede óptica de multiplexação por divisão de comprimento de onda e método associado a presente invenção não requer controle e via de comutação por equipamento de estação terminal e previne a deterioração da qualidade do sinal quando ocorre uma falha do cabo. um dispositivo derivando comprimento de onda conectado com três ou mais estações monitora um sinal de uplink recebido de cada estação, e quando detecta a ausência de um sinal de uplink recebido de qualquer uma estação, emite luz provisória em vez do sinal ausente, realiza multiplexação/desmultiplexação para a luz provisória e um sinal de uplink recebido a partir de uma estação excluindo a dita qualquer estação, e emite o sinal multiplexado/desmultiplexado. todos os ditos processos são realizados dentro do dispositivo de derivação de comprimento de onda.
