Návrh sítě FTTB / FTTB Network Design

Reichert, Pavel January 2008 (has links)
The purpose of this master’s thesis is to explain the issues of the FTTx network design. The main idea of this work is to describe to readers the methods of the designing the optical access networks. Especially we will speak about the building technologies and different topologies used in a practice. The different technologies of optical access networks’ building and various parameters, which are necessary to take into account in the designing of these networks, will be introduced. In the theoretical part, methods of measurement, which are like the needed part of each optical access networks’ building, will be described. Two purposes of the FTTB networks with all proprieties will be made and offered. One purpose will be solved by Point to Point topology and the second purpose will be solved by Point to Multipoint topology. Following the confrontation one of these purposes will be chosen and realized. By ITU recommendation, measurements will be performed on the built optical trace. The final protocols will be elaborated from these measurements. The built trace with all final reports will be prepared for assignment to the subscriber.

Technologie datových přenosů v optických přístupových sítích FTTx / The data transfer technologies in optical access networks (FTTx)

Matušík, Lukáš January 2009 (has links)
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.
