Wavelength Division Multiplexing (WDM) technology as it is deployed in wide-area and metropolitan-area public networks is also expected to impact parts of corporate networks in the future. This paper surveys the current environment of corporate networks and discusses the requirements that will eventually demand WDM. First WDM deployments in the private network market are described as indicators for future opportunities for which lower cost is the key prerequisite. Technical approaches to achieve this are shown using two examples of existing research projects.
