Abstract

The dynamic switching of channels to adapt the capacity to the actually occurring traffic load is a promising method to improve the energy efficiency in optical networks. However, this approach is limited by the possible generation of optical power transients, which are able to disturb the transmission of the remaining channels. In transparent networks, spreading of transients can occur across several nodes. In this paper, we demonstrate the restrictions of the dynamic channel switching by the consideration of optical power transients and shows how to minimize these limitations.
