In this paper, the authors throw light on what optical networks are really capable of and what developments have been made in terms of the higher bandwidth provided by them in an adaptive way, whenever and wherever required. How optical fibers have been extensively implemented now-a-days in all types of communication networks. Multiple ways of increasing the capacity by using the WDM (Wavelength Division Multiplexing) technique. A brief survey on the recent developments on 'Flexible' optical networking. This paper deals with the evaluation of the performance of WDM networks.
