WAVELENGTH-DIVISION MULTIPLEXING DEVICE FOR OPTICAL ATS Russian patent published in 2010 - IPC H04J14/02 H04B10/12 

FIELD: physics.

SUBSTANCE: invention is designed for fibre optic lines of optical ATS (OATS) for broadband city and inter-city video-telephone, multimedia and telephone communication. The multiplexing device has an optical channel on several repeatedly used prisms which is common for all or for a large number of fibre optic lines of city and intercity OATS. In a subscriber access system with capacity of up to 80000 channels, one device will multiplex into a main line with average density of up to 500-1000 channels from terminal lines with low density Δλ=1 nm, and a terminal device will multiplex into a line with low density of up to 50 channels from subscriber terminals.

EFFECT: design of optical multiplexing devices which are easy to adjust to any range from visible to infrared waves and to any wavelength in that range.
