Wavelength converter placement optimization in WDM network

A recent technology of information transmission in the fiber optics area. Wavelength Converters are key components in advanced WDM networks. Optical-transmission techniques have been researched for quite some time, Optical “networking” studies have been conducted only over the past dozen years or so. The field has matured enormously over this time. A large number of start ups have been formed, and Optical WDM technology is being deployed in the marketplace at a very rapid. In WDM networks, an optical fiber can carry several simultaneous wavelength channels. Each wavelength has to be different in the same fiber. The number of wavelengths that each fiber can carry is limited by the physical characteristic of the fiber and the state of optical technology, which is used to combine these wavelengths onto to the fiber and isolate them of the fiber. This motivated to do the research in the wavelength converter placement problem. The success of WDM networks depends heavily on the available optical device technology.
