Abstract

Mittels eines Zirkulators (2) ist an eine WDM-Übertragungsstrecke (1) eine Abgleichvorrichtung mit einem optischen Spektrographen (4), einem optischen Abschwächer (7) und einem Reflektor (8) angeschlossen. Der Spektrograph ist vorzugsweise ein Phased Array mit unterschiedlich langen Wellenleitern (41) zwischen Freifeldbereichen (40, 42) und teilt das ankommende Gesamtsignal auf verschiedene Kanäle auf, die von dem Abschwächer auf gleiche Leistungspegel reduziert werden. Der Reflektor reflektiert die Signale, die die Vorrichtung erneut passieren und über den Zirkulator wieder in die Übertragungsstrecke eingespeist werden.
