The Berlin City Ring—a Testbed for Future Metropolitan Networks

The Berlin City Ring—a Testbed for Future Metropolitan Networks Dense wavelength division multiplexing (DWDM) is the key technology for future data transport. It combines transmission of data rates up to several Tb/s [1] with an overall transparency to data format and bit rate. The expected huge bandwidth demand in the near future requires an adaptability of DWDM transmission technology to metropolitan networks. Therefore, dynamically configurable DWDM transmission technology for bit rates up to 10 Gb/s has been investigated in a field trial in Berlin. This field trial is part of the KomNet research project. It is the goal of this field trial to optimize DWDM systems to metropolitan network requirements. Several aspects are in this paper: (i) A network simulation tool is described which helps to enlighten the profitability of statically and dynamically configured network nodes. (ii) A newly developed technology to add and drop single-wavelength channels is explained. (iii) The scalability of the approach is demonstrated with an aggregate capacity of 0.8 Tb/s. The equipment has already been installed in the field and is ready for experiments. Photonic Network Communications Springer Journals
