Maximum number of wavelengths that a MUX/DEMUX board can process in the OSN 6800
107A maximum of 80 wavelengths can be processed by the ITL board. The ITL board multiplexes 40 odd wavelengths and 40 even wavelengths of M40 boards into 80 wavelengths, and then demultiplexes the 80 wavelengths into 40 odd wavelengths and 40 even wavelengths and sends the wavelengths to D40 boards.
