Abstract

The device 10 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 13, so that the data flow leaves the device 10 after undergoing reflection by the two filters. The plate 13 is mounted on a support 14 that can be rotated in one direction or the other to vary the tuned wavelength of the filters. <IMAGE>
