Abstract

A closed loop amplified ring for metropolitan (Fig. 3) area DWDM networks. The ring includes a reference node (104) where channels that originate at the reference node are added to the ring at a reference power level and where the reference power level is used to set power levels of all other channels that are added to the ring.
