Viewing on the rising demand and keeping eye on the expected future market of telecommunication industry, now a days all the service providers are much more focused on the efficiency part of their network system. The technique of routing and wavelength assignment (RWA) in a WDM/DWDM network is closely related to the performance of the network and ultimately the efficiency of the entire network system is based on it. Where, all the service providers trying hard to maintain a satisfactory level of transmission quality, there various types of physical layer impairments are obstacles for them. This research work proposes a technique for the reduction of four-wave mixing (FWM) effect by using an efficient RWA scheme for WDM/DWDM networks. However, we have gone through numbers of RWA schemes from various literature and found those are less efficient to provide better quality of transmission. In this thesis, we have proposed a WA scheme which partitions the entire fiber transmission window into ’N’ number of bands and assigns wavelength randomly from any one of the band based on connection length. Finally, the analytical result proves that, this mechanism reduces the FWM effect significantly which is computed in terms of blocking probability. It says higher the partition, lower the FWM effect.
