Abstract- This article covers functions and applications of DWDM system components. The operation of each component is discussed individually. DWDM terminology like Attenuation dispersion and optical signal to noise ratio OSNR are measures of optical signal quality and are the key factors involved in DWDM system design and operation. From transmitter to receiver the quality of the optical signal and the path across which it travels determines if it is successfully detected and recovered at the receiving end. A description of each type of signal measure and its relationship to a DWDM system is given.
