Abstract

IL DISPOSITIVO COMPRENDE UN PRIMO CIRCOLATORE OTTICO (C1) IN SERIE ALLA LINEA (1e, 1u) PER RICEVERE UN FLUSSO DI SEGNALI COMPRENDENTE UNA PORTANTE DA ESTRARRE, MODULATA DA UN SEGNALE D'INFORMAZIONE, E TRASMETTERE UN FLUSSO DI SEGNALI COMPRENDENTE LA STESSA PORTANTE, REINSERITA NEL FLUSSO DOPO ESSER STATA MODULATA CON UN DIFFERENTE SEGNALE D'INFORMAZIONE, E UN SECONDO CIRCOLATORE (C2) COLLEGATO A ORGANI DI TRATTAMENTO LOCALE DELLE INFORMAZIONI, A CUI FORNISCE LA PORTANTE ESTRATTA E DA CUI RICEVE LA PORTANTE DA REINSERIRE. TRA I DUE CIRCOLATORI E' DISPOSTO UN FILTRO OTTICO PASSA-BANDA IN FIBRA (FP) ACCORDABILE SULLA LUNGHEZZA D'ONDA DELLA PORTANTE.
