New advances in enabling technologies, as well as the growth of Internet traffic have continuously driven the fast evolution of networks. All optical packet switching provides high throughput, rich routing functionalities and excellent flexibility. These characteristics make it an excellent candidate for next-generation metropolitan area networks, which will be much more dynamic and demanding than today?s networks. This study proposes Dense Wavelength Division Multiplexing (DWDM) based data networking using fiber optical backbone in a Dhaka city of Bangladesh. DWDM is used in this study as a backbone controller from centralized location. Two DWDM devices are placed at the two important location of the Dhaka city. DWDM based optical infrastructure is a future demanded technology.
