Fiber-Optic Transmission Networks

Next generation optical communication systems will be characterized by increasing data rates, dynamic adaptation to the actual traffic demands and improved energy efficiency. In the future all-optical meshed networks, transparent optical paths, should be set up automatically, providing bandwidth on demand and automatically shutting down unused resources. §In the first part of the book the author elaborates on the design of optical transmission systems. Appropriate design of an optical core network is crucial. In this book several alternative methods for reducing the simulation time are proposed. §In the second part the operation of optical networks is discussed. Fiber optic core networks are evolving rapidly from static point-to-point transmission systems to meshed networks with transparent optical cross-connects, making the dynamic reconfiguration of the network possible and leading to longer transparent transmission distances. In this book constraint-based routing and regenerator placement are examined on the basis of fast analytical models for approximating the signal quality. Finally, the book investigates how the energy efficiency of an optical core network can be increased considerably.
