Linear and nonlinear phenomena in optical access networks

The aim of this thesis is an explanation of the problem linear and nonlinear phenomena in optical access networks. In the first chapter refers to a description of the optical fiber, description of the optical environment and the main part is theoretical and mathematical description of phenomena that operate in optical fibers. It is therefore a specific attenuation, dispersion, phenomena of second and third-order, nonlinear light scattering and solitons. Then there is the dismantling brief overview of the distribution of access networks and their description. The second part deals with specific simulation of these phenomena in the simulation program OptSim 5.2. All connections will be implemented in the block diagram Sample-Mode, in which using appropriate units and setting the right parameters, we will try to confirm the theoretical assumptions of the first part
