Germany-wide DWDM field trial: transparent connection of a long haul link and a multiclient metro network

We report on error-free multiclient transmission over a Germany-wide all-optical, configurable DWDM system. The performance of the transparent connection of a metropolitan area network and a bi-directional long haul system is investigated under real-world conditions. We report on the topology of SIEMENS part of the Germany-wide field trial KOMNET and results of transparent interconnections between different optical domains.
