Fiber optical transmission system
Horský, Tomáš ; Münster, Petr (referee) ; Dejdar, Petr (advisor)
Bachelor thesis deals with the program processing for the simulation of dispersion on the optical transmission. Parameters of optical fiber, such as attenuation, diffusion, dispersion, and bandwidth are described in the theoretical part. The main focus is on dispersion while being the key parameter of this work. In the practical part, the measurement characteristics of the eye diagram and its analysis are discussed. Simulator of dispersion can serve both for simulation as well as a measuring device for real transmission routes.

Extension of optical fiber transmission system
Horský, Tomáš ; Tomašov, Adrián (referee) ; Dejdar, Petr (advisor)
The diploma thesis describes the elaboration of a program for the simulation of an optical transmission path. The work introduces the basic parameters of optical transmission, such as attenuation, dispersion and bandwidth. Furthermore, the techniques of line code and error detection are described in the work, especially a cyclic redundancy sum. The key parameter of this thesis is dispersion of the optical signal. The work includes the characteristics of the eye diagram and its analysis. The resulting program can also be used to measure the real transmission route and its parameters.

The data transfer technologies in optical access networks (FTTx)
Matušík, Lukáš ; Míča, Ivan (referee) ; Reichert, Pavel (advisor)
The objective of diploma thesis is describe problems connected with designed of FTTX networks and bring the reader problems of data transmission in optical acces networks the type of PON. In the introduction are mentinoned individual technologies that already operate, and there are describe advantages disadvantages of the use topology point-to-point and point-to-multipoint. In the following chapters are dealt with problems with data broadcasting in the direction from final participant. In the other part of diploma thesis are described elements, that were used for the proposed transmission route. The own PON acces network was presented on the basis information obtained by comparing the various networks and the elements involved in them. The network presented in conclusion diploma thesis is involved in topology point to multipoint. This transmission route is simulated in the program that allows the involvement of network by the user’s need with real values. The acces network is simulated for different transmission speed and different distances. The assesment of created optical route results from the measured values, theirs source is program OptiSystem, these values are summarized in the final chapter.
