Abstract

Patente de Invenção: "DISPOSITIVO MULTIPLEX-ADD-DROPCONFIGURáVEL DE SISTEMA DETRANSMISSãO-MULTIPLEX-COMPRIMENTO DE ONDAóTICO". O dispositivo multiplex-Add-Drop apresenta um grupo defiltros (1) que divide um sinal-WDM (WMS1) entrante em váriosgrupos de canais (G1 a G4) de canais-WDM vizinhos (K1 a K8...).Cada grupo de canais é aplicado a um módulo (M1-M4) para umanova configuração. Um primeiro tipo de módulo (MM) possibilitauma configuração manual de canais-Add-Drop de canais WDM(K1 a K8...) comutados diretamente enquanto um segundo tipo demódulo (MF) possibilita uma configuração remota. Um quarto tipode módulo (MF25, MF26, MF27) possibilita uma configuraçãoremota de canais-Drop-Continue (K25-K32).
