ABSTRACT:
An arrangement for the implementation of an add/drop method in optical signals transmitted wavelength-division multiplex in which an interferometer includes a divider for generating signal parts from an optical signal which are forwarded to the two interferometer branches, a superposition device for superimposing the signal parts from the branches, respective add/drop means in each branch, and a phase delay in one branch.
