Abstract

IL COMMUTATORE OTTICO PER RETI A COMMUTAZIONE VELOCE DI CELLA COMPRENDE UNA RETE DI INTERCONNESSIONE OTTICA (CM) E UNA RETE ELETTRICA DI COMANDO (CT). PER SFRUTTARE APPIENO LE POTENZIALITA' DEI COMPONENTI OTTICI, SUPERANDO I VINCOLI IMPOSTI DAI LIMITI DI VELOCITA' OPERATIVA DEI COMPONENTI ELETTRONICI, OGNI INGRESSO (IN1 ... INk) DELLA RETE DI INTERCONNESSIONE (CM) E' ASSOCIATO A MEZZI (PAC1 ... PACK) PER FORMARE AGGREGATI DI CELLE CHE DEVONO SEGUIRE UNO STESSO PERCORSO ATTRAVERSO LA RETE DI INTERCONNESSIONE E COMPRIMERE NEL TEMPO GLI AGGREGATI, E OGNI USCITA (OUI ... OUk) E' ASSOCIATA A MEZZI (PED1..PEDk) DI ESPANSIONE TEMPORALE E SEPARAZIONE DELLE CELLE DEGLI AGGREGATI. (Fig. 1).
