Metropolitan DWDM a dynamically configurable ring for the KomNetfield trial in Berlin.

We present the system concept of a dynamically configurable all-optical add/drop multiplexer for metropolitan wavelength division multiplex rings using dense channel spacing (DWDM). We first outline the essential network requirements. Subsequently, an optical system concept is presented that meets t...
