FIELD: physics. ^ SUBSTANCE: multichannel controlled input/output optical multiplexer for fibre-optic communication systems with wavelength-division multiplexing of 2N channels, where N is an integer and NëÑ2, optical frequencies of which can be adjusted at constant spectral interval ö0 between neighbouring channels, for input/output of 2M channels, where M is an integer and 1ëñM<N, has a controlled optical demultiplexer with 1ù2M configuration, controlled optical multiplexer with configuration 2Mù1, 2M controlled input/output optical multiplexers and a controller for controlling adjustment of spectral characteristics of the said demultiplexer, multiplexer and 2M input/output multiplexers. ^ EFFECT: provision for given transmission capacity of filtering devices in the multiplexer with possibility of input-output of channels with given frequencies through control of spectral characteristics of these filtering devices. ^ 11 cl, 15 dwg, 3 tbl |
