ABSTRACT:
In a circuit arrangement for optical frequency conversion, having a switchable input filter arrangement with a wavelength channel filter of a wavelength multiplexer/demultiplexer which is formed using a number of such channel filters, which filter can be connected via a 1:n fiber switch to an input fiber and is passed through by the input signal in the multiplex operating direction, a frequency converter which is passed through in opposite directions by the input signal and a pump laser signal, and an output filter, the output filter is formed by a wavelength channel filter of the wavelength multiplexer/demultiplexer, which filter is passed through by the output signal in the demultiplex operating direction and is connected on the output side to the output fiber.
