Abstract :
The authors introduce a novel upgrade technique for currently installed 1.3 mu m regenerated optical transmission systems that can be implemented with minimal disturbance to existing plant. The method uses erbium fibre amplifiers to bypass regenerators thus opening the 1.5 mu m window. The concept is discussed and an experiment reported to illustrate the scheme.
