Wavelength converter location and optical fiber dimensioning for limited channel convertible optical networks

This paper introduces two efficient methods for the design of multiwavelength optical networks. First, we suggest a wavelength converter location method if converters are located at some nodes. Second, we suggest a decision method about how many optical fibers must be required at each link to satisfy all connection demands. The second method is also for the network with wavelength converters at some nodes. These two methods are based on a new optical path scheme in a network of arbitrary topology. In the new optical path scheme, called the partial wavelength path (PWP) scheme, limited channel converters are located at not all, but some nodes. Limited channel converter allows a limited number of optical paths to share wavelength conversion. Static routing and wavelength assignment is assumed
