Optical WDM coupling systems

摘要

An optical coupling system for wavelength-individual through-connection between wavelength-division multiplex (WDM) a plurality of input and output fibers with simultaneous possibility of wavelength conversion is provided. A respective optical splitter individually associated to an input fiber multiplies the WDM signal incoming on the appertaining input fiber into axm WDM signals that are supplied to axm tunable optical filters, wherein a is the plurality of output fibers and m is the plurality of wavelengths combined in a respective wavelength-division multiplex on an output fiber. Respectively, a plurality e of tunable filters connected to the plurality e of input fibers, combined at the output side via an optical combiner, lead to a wavelength converter that is connected to an input of a wavelength-division multiplexer preceding an output fiber.
