Optical technology is the principal component of nowadays backbone networks and the whole Internet. The technological developments that paved the way for switching in the optical domain introduced many challenges, such as lightpath topology design, lightpath routing and network-wide spectrum allocation. The solutions to these problems are highly affected by the underlying network topology. Therefore, we study the effects of the fiber network topology on the static routing and wavelength assignment (RWA) as well as the capital expenditures (CAPEX) using several spatial network models, which resemble real network topologies, including networks with complex structures.
