FIELD: information technologies. ^ SUBSTANCE: device for fiber-optic communication system with wavelength-division multiplexing 2N channels where N is integer and NëÑ2 with spectral interval between adjacent channels öv0 for performing input/output of 2M channels where M is integer and 1ëñM<N, has one entering port, one exiting port, 2M output ports, 2M input ports and contains: controlled optical input/output multiplexer, optical demultiplexer of "1ù2M" configuration, optical multiplexer of "2Mù1" configuration and controller. This device can be used as multichannel controlled or multichannel reconfigurable optical input/output multiplexer. ^ EFFECT: performing input and output of multiple channels from optical signal with channel wavelength-division multiplexing using controlled dynamic filtering elements capacity restructuring. ^ 13 cl, 16 dwg, 3 tbl |
