Abstract

MÉTODO E APARELHO DE DETECÇÃO DE PORTA. Este pedido fornece um método e aparelho de detecção de porta. Nas soluções técnicas deste pedido, uma OLT ou uma ONU pode determinar, com base em pelo menos dois comprimentos de onda e uma correspondência predefinida, informações de porta que são de um divisor óptico e que correspondem à ONU. Ou seja, uma porta de ramificação direta ou indiretamente conectada à ONU é definida usando os pelo menos dois comprimentos de onda. Desta forma, diferentes portas de ramificação podem ser distinguidas usando combinações de uma pluralidade de comprimentos de onda, para definir uma grande quantidade de portas de ramificação do divisor óptico usando combinações livres de uma pequena quantidade de comprimentos de onda. Isso ajuda a evitar um problema de uma quantidade insuficiente de comprimentos de onda de monitoramento devido a uma limitação de uma faixa de comprimentos de onda de monitoramento, e ajuda a determinar com precisão uma relação de conexão entre uma ONU e uma porta de ramificação do divisor óptico.
