Abstract
As the technology is improving so are the demands of end users and their applications increasing. This paper presents a reviewed survey of the available literature on Wavelength- division multiplexing and different type of topologies considered for Routing & Wavelength Assignment. A categorization has been provided based on the different routing techniques. It highlights the functional classification of RWA & handling the issues related to the feasibility of 3G & 4G technologies. Optical networks are capable to fulfil the increasing demand of high- speed networks due to rapid growth in Internet technology. Rough sets are suitable for handling different types of uncertainty in different topologies. But HighEnd resources need good algorithmic approach to send & receive data. Today, the tendency of several telecommunication companies is towards optical networks as the light has higher frequencies and the shorter wavelength. An extensive bibliography is also included.
