Abstract

Det er tilveiebrakt en optisk repeater som inkluderer minst fire optiske forsterkere som hver tilfører optisk forsterkning til et optisk signal som beveger seg i en forskjellig enveisoptisk fiber, hvilke samlet danner minst to toveis par av optiske fibere. Repeateren inkluderer også en første flerhet av pumpekilder for å tilveiebringe pumpeenergi til en første optisk fiber som er lokalisert i et første av de optiske fiberpar og en annen optisk fiber som er lokalisert i et annet av de optiske fiberpar. Den første optiske fiber og den annen optiske fiber bærer optiske signaler som beveger seg i en felles retning. Et første kombinatorarrangement kombinerer pumpeenergien fra den første flerhet av pumpekilder og fordeler den til de optiske forsterkere som tilfører forsterkning til optiske signaler som bevegeler i den første og den annen optiske fiber. En annen flerhet av pumpekilder tilveiebringer pumpeenergi til en tredje optisk fiber som er lokalisert i det første optiske fiberpar og en fjerde optisk fiber som er lokalisert i det annet optiske fiberpar. Den tredje optiske fiber og den fjerde optiske fiber bærer optiske signaler som beveger seg i en felles retning som er motsatt i forhold til den for den første og annen optiske fiber. Et annet kombinatorarrangement kombinerer pumpeenergien fra den annen flerhet av pumpekilder og fordeler den til de optiske forsterkere som tilfører forsterkning til optiske signaler som beveger seg i den tredje og den fjerde optiske fiber.
