BONN, Germany, August 7 -- The ultra long-distance optical system LambdaXtreme Transport, developed by Lucent Technologies, passed Deutsche Telekom field trials in May, when it transmitted 40-Gbit/s signals over more than 734 km with a standard fiber (SSMF), with no electrical regeneration. "The success of the LambdaXtreme Transport tests has proved that our 40G technology is fully fit for everyday use", said Rainer Fechner, head of Lucent's Nuremberg facility and responsible for Lucent's R & D activities in Germany, where product specialists from Nuremberg supported and conducted significant parts of the test.
