What is Dense wavelength division multiplexing (DWDM) ?

Dense wavelength division multiplexing  (DWDM)             " The emergence of DWDM is one of the most recent and important phenomena in the development of fiber optic transmission technology. In the following discussion we briefly trace the stages of fiber optic technology and the place of DWDM in that development. We then examine the functions and components of a DWDM system, including the enabling technologies, and conclude with a high-level description of the operation of a DWDM system". Wdm with two channels
