MULTICHANNEL CONTROLLED INPUT/OUTPUT OPTICAL MULTIPLEXER Russian patent published in 2009 - IPC H04J14/02 

FIELD: physics.

SUBSTANCE: multichannel controlled input/output optical multiplexer for fibre-optic communication systems with wavelength-division multiplexing of 2^N channels, where N is an integer and N≥2, optical frequencies of which can be adjusted at constant spectral interval Δν₀ between neighbouring channels, for input/output of 2^M channels, where M is an integer and 1≤M<N, has a controlled optical demultiplexer with 1×2^M configuration, controlled optical multiplexer with configuration 2^M×1, 2^M 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.
