CA 2290311

Modular filter for extracting and/or inserting or processing optical signals in multiple-wavelength optical telecommunications systems, comprising a wavelength multiplexer/demultiplexer device having N first ports for receiving a multiple-wavelength signal and a number N of second ports into which the said wavelengths are divided, and N/2 branches which interconnect the said N second ports into which the said wavelengths are divided. In each of the said branches there is a signal processor device for extracting and inserting the wavelengths circulating in the branch, this device comprising a wavelength-selective filter.
