Design of optical amplifier
Somora, Rastislav ; Číž, Radim (referee) ; Slavíček, Karel (advisor)
This Bachelor's thesis deals with design and construction of support circuits for a modern optical amplifier the SOA. In the first chapter, optical transmitting medium with its physical properties and types of used cabels is described. The overview includes a list of optical cables, their damping properties and parasitic effects which can occur durring comunication. Next chapter is focused on the optical signal sources used in modern data networks, describes their internal structure and physical essence. Third chapter is dedicated to designing the optical amplifier with the SOA circuit. It focuses on the right choice of parts, their arrangement and layout of the design. Last chapter deals with set up, calibration and control of the optical amplifier module.

Design of semiconductor optical amplifier
Somora, Rastislav ; Hanák, Pavel (referee) ; Slavíček, Karel (advisor)
Diploma thesis deals with the construction of a moder semiconductor optical amplifier SOA. In the first chapter optical comunication and the use of optical amplifiers is described. In the next chapter some types of optical fibers, their chemical composition and properties are described in detail. The third chapter overviews optical amplifiers, their use today, describes their advantages and disadvantages and their proper use in optical comunications. The fourth chapter describes the solution of the objective, the right layout of separate blocks and connections used in measurements. Fifth chapter describes used components, describes their basic parameters and proper use in circuit. The last chapter evaluates outputs of measurements and their impact on the objective.

The proposal to use agile development procedures of Scrum framework with UML modeling language applicable for creating websites
Kučera, Antonín ; Oškrdal, Václav (advisor) ; Luc, Ladislav (referee)
The main goal of this diploma thesis is the proposal to use agile development procedures of Scrum framework with UML modeling language applicable for creating websites of small scale. The emphasis is especially put on creating a practically usable type model of the websites. The theoretical part of the thesis has two main chapters. In the "Agile methodology" chapter are listed principles of agile approach to creating software. The next part of this chapter is focus on agile methodologies (Scrum, XP, ASD, FDD, DSDM, LD and Crystal). In the "UML" chapter is introduced modeling language UML and its principles. The next part of this chapter is focus on UML diagrams used in practical part of this thesis (use case diagram, class diagram, sequence diagram, activity diagram and deployment diagram). The practical part of this thesis focuses on the design type model for creating websites of small scale. The type model is based both on the theoretical part of this work and practical experience of the author. In the first part is introduced scheme of model, where is shown the mutual relationship of individual phases. In the next part of this chapter are discussed the individual phases where is used the principle of agile development framework Scrum and examples of use of the UML diagrams.
