[February 19, 2004] Siemens ICN: On the Way to Dynamic Optical Networks Munich, Germany – 19 February 2004 - At the conference on Optical Fiber Communication in Los Angeles, Siemens ICN will report on concepts to reduce the effects of Raman transients enabling carriers to operate dynamic optical networks and increasing resilience.Raman transients can severely degrade the reach and stability of transparent optical networks. Simultaneous unintended deactivation of many channels, resulting for example from a fiber cut in front of an optical add drop multiplexer (OADM) or a subband component failure, induce power envelope fluctuations which endanger error free operation of the surviving channels. Coping with Raman transients will be a major issue in the design of next generation transparent optical networks as rerouting processes and reconfiguration are gaining in importance. Siemens ICN demonstrates that compensation using for example a controlled tilt filter and variable optical attenuator (VOA) is a valuable contribution to combat Raman transients and to ensure stable error free operation. The presentation will be held on February 23rd at 5:30 pm in the Concourse Hall of the Los Angeles Convention Center Siemens Information and Communication Networks (ICN) is a leading global provider of communication solutions for enterprises and carriers. Its portfolio ranges from real-time IP-based applications, IP convergence solutions and broadband access systems to optical transport networks. ICN also provides consulting and services. With its innovative LifeWorks concept, ICN is developing a uniform platform that transcends the boundaries of corporate, fixed and mobile network, enabling providers to offer new services and enterprises to boost productivity. ICN posted sales of 7.1 billion euros in fiscal 2003 (year-end September 30) and employed 33,000 people.
