Nové generace pasivních optických přístupových sítí

Abstract

The aim of this bachelor thesis is to describe the function of WDM technologies and show how to use these technologies in passive optical networks and then create a simulation of this network and compare the results from this simulation with those from practical measurements. This thesis is divided into four main parts. In the first part I describe the existing passive optical access networks and basic functional components that are used in these networks. In the second chapter I describe the new technology called WDM and the new components used for the proper function of this technology, such as an AWG, tunable lasers, optical sources and detectors. I also describe the new topologies with WDM technology. The third chapter deals with the simulations in the Optiwave Optisystem where I simulate WDM network and I describe the components used and their settings. In the last chapter I compare the results from simulations with practical measurements. I also assess whether the simulation has any benefits and if the results are so accurate that they can be considered final.
