Abstract
The device 100 comprises a pair of interference filters 11, 12, nominally identical, one of which performs the function of extraction of a carrier from a wavelength division data flow and the other inserts it. The filters 11, 12 are placed in parallel planes and are constrained on opposite sides by a transparent plate 103, so that the data flow leaves the device 100 after undergoing reflection by the two filters. The support 103 can be rotated in one direction or the other to vary the tuned wavelength of the filters. <IMAGE>
