OPTISCHES ÜBERTRAGUNGSSYSTEM MIT EINER OPTISCHEN PHASENKONJUGATIONSVORRICHTUNG

摘要

An optical system having an optical fiber path suitable for propagating an optical signal at least in a first direction, a plurality of optical gain modules disposed along the optical fiber path so as to divide the optical fiber path in N spans of optical fiber. Each span of optical fiber has at least one transmission optical fiber connected downstream from the optical gain modules. An optical phase conjugation device is disposed at a predetermined distance downstream from one of the optical gain modules.
