Abstract

Et system for overføring av optiske signaler under en undervanns oljefeltoperasjoner omfatter en undervanns fiberoptisk signalbærer. Den fiberoptiske signalbærer inkluderer en første optisk fiber som har minst én dopet seksjon som virker som en forsterker på optiske signaler som passerer derigjennom når den dopede seksjon forsynes med optisk energi. En annen optisk fiber er anordnet langs den første optiske fiber for å føre optisk energi. En optisk kopler mellom den annen optiske fiber og den minst ene dopede seksjon tilfører optisk energi fra den annen optiske fiber til den første optiske fiber. Minst én sensor tilveiebringer optiske signaler til den første optiske fiber. En optisk energikilde tilfører optisk energi til den annen optiske fiber.
