Abstract

Et optisk kommunikasjonssystem (10) omfatter flere gjensidig sammenkoblede, toveis optiske bølgelederringer (20, 30, 40, 50, 60) hvor stråling modulert med kommunikasjonstrafikk brer seg ut. Strålingen er delt opp i 32 adskilte bølgebånd. Der kommunikasjonstrafikk som brer seg ut i ringene, overføres fra en ring til en annen i systemet (10), er det anordnet grensesnittutstyr (70, 80, 90, 100, 110, 120). Hvert grensesnittutstyr er istand til å skape en heloptisk, bølgelengderekonfigurerbar kommunikasjonsforbindelse mellom ringene. Konvertering i det enkelte grensesnitt av optisk stråling til tilsvarende elektriske signaler er ikke påkrevet når kommunikasjonstrafikk overføres fra en ring til en annen, hvilket gir systemet en potensielt større kommunikasjonsbåndbredde sammen-lignet med konvensjonelle optiske kommunikasjonssystemer. Om nødvendig kan grensesnittutstyret (70, 80, 90, 100, 110, 120) inneholde en eller flere regenererende forsterkere (440, 850, 852, 854, 856, 858, 860, 862, 864) og bølgelengdesvitsjende transpondere (1332, 1410).
