Abstract: With wavelength division multiplexing (WDM) several optical signals can be transferred in a single optical fiber [6][7]. This technology allows more efficient use of the huge capacity of an optical fiber but also poses new network design and management problems, especially when wavelength conversion is not possible in the nodes. In this paper we consider the routing and wavelength assignment problem in such networks. In a single fibre case the wavelength assignment is essentially a graph coloring problem once the routes are fixed. With multiple-fibres the problem changes a little and can no longer be presented as graph node coloring. Chosen routing has great impact to the final solution and an iterative algorithm for choosing the routes is briefly studied.
