Abstract
The invention relates to a module for multiplexing and/or demultiplexing optical signals, having at least one wavelength-selective filter for multiplexing or demultiplexing into the module optical signals which have been coupled in or out, light beams of at least one optical channel respectively striking a wavelength-selective filter at a specific angle of incidence and, in the process, being separated from the light beams of other optical channels or being combined therewith. According to the invention, at least one wavelength-selective filter (Fi) can be set with reference to the angle of incidence of the light beams. The invention makes available a module in the case of which the center wavelength of a filter can be set precisely on the basis of the adjustability of the angle of incidence and, moreover, a specific filter (Fi) can also be used for several wavelengths.
