MULTICHANNEL OPTICAL INPUT/OUTPUT MULTIPLEXER WITH DYNAMIC FUNCTIONALITY Russian patent published in 2010 - IPC H04J14/02 

FIELD: information technologies.

SUBSTANCE: device for fiber-optic communication system with wavelength-division multiplexing 2^N channels where N is integer and N≥2 with spectral interval between adjacent channels Δv₀ for performing input/output of 2^M channels where M is integer and 1≤M<N, has one entering port, one exiting port, 2^M output ports, 2^M input ports and contains: controlled optical input/output multiplexer, optical demultiplexer of "1×2^M" configuration, optical multiplexer of "2^M×1" 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.
