Abstract

filtro de multiplexação por divisão de comprimento de onda a presente invenção descreve um filtro de multiplexação por divisão de comprimento de onda que pode satisfazer requerimentos de coexistência de diferentes sistemas de pon e um sistema de detecção de linha óptica. o filtro de multiplexação por divisão de comprimento de onda compreende uma pluralidade de filtros que são configurados: em uma direção de ligação descendente, para receber um primeiro sinal de pulso óptico produzido por um primeiro sistema de pon, um segundo sinal de pulso óptico produzido por um segundo sistema de pon ou obtido pela acoplagem de um sinal de saída do segundo sistema de pon e um sinal de vídeo, e um terceiro sinal de pulso óptico enviado a partir de um refletômetro óptico no domínio de tempo, e para acoplar o primeiro sinal de pulso óptico, o segundo sinal de pulso óptico e o terceiro sinal de pulso óptico em uma rede de divisão óptica; e em uma direção ascendente, para dividir um sinal de pulso óptico de ligação ascendente de acordo com bandas de comprimento de onda, para transmitir um sinal de pulso óptico em uma primeira faixa de comprimento de onda de ligação ascendente para o primeiro sistema de pon, para transmitir um sinal de pulso óptico em uma segunda faixa de comprimento de onda de ligação ascendente para o segundo sistema de pon, e para transmitir um sinal óptico em uma terceira faixa de comprimento de onda de ligação ascendente para o refletômetro óptico no domínio de tempo.
