Dense Wavelength Division Multiplexing Optical Network System [PDF]
International Journal of Electrical and Computer Engineering (IJECE), 2011 In this paper, a dense wavelength division multiplexing (DWDM) system with 64 modulated channels 50 GHz spacing covering 25.2-nm bandwidth has been demonstrated. When optical signals are to travel over long distances, it’s be faded and spread out. So, it is necessary to strengthen the signal at intervals.
