Polarization mode dispersion
Turský, Aleš ; Dostál, Otto (referee) ; Filka, Miloslav (advisor)
The work deals with dispersive effects of single mode fibers. We learn about the chromatic dispersion, the main attention is paid to the Polarization Mode Dispersion. We clarify the root cause origin of the Polarization Mode Dispersion describing parameters and its effect on transmitted data. Further on, the works dedicates to measure methods of the Polarization Mode Dispersion which is the interferometric method or the POTDR method. We explain the ways of the PMD removal at contemporary optic routes and options of PMD compensation by using compensators of various types. There is also mentioned the possibility of profiting from the soliton transmission. The last chapter deals with measuring of a real optic route. It includes measured data and its evaluation due to the ITU-T demands.

Measurement and evaluation of dispersions in optical fibre
Očenášek, Jan ; Čučka, Milan (referee) ; Vojtěch, Josef (advisor)
This semestral project deals with measurement and evaluation of the dispersion in the optical fiber. Introduction of the work is focused on the description of the principle of optical fiber and optical environment. Another part is devoted to a detailed description of polarization mode dispersion - PMD, including the causes of which are divided into internal and external. Because of these impacts of the differential group delay DGD, which results in time delay of each polarization modes to each other and hence to reduce the transmission speed. Polarization mode dispersion is one of the most limiting factors for the realization of high-speed optical transmission, so in the next section describes the measurement and compensation of PMD effect.

Temperature Dependence of PMD
Drábek, Jakub ; Hanák, Pavel (referee) ; Münster, Petr (advisor)
Bacherol thesis describes the problems of polarization mode dispersion-PMD. Size of the delay PMD is a random variable that varies in time. When operating at high data rate communication links is one of the major problem of the optical fiber. PMD value affects many different environmental influences as temperature, and therefore the measurement of PMD become standard in deploying high-speed optical networks.

Polarization mode dispersion - PMD
Ťupa, Martin ; Dostál, Otto (referee) ; Filka, Miloslav (advisor)
Polarization mode dispersion PMD becomes the most limiting factors for achieving high-speed optical transmission. The size of the dierencial group delay between the polarization plane is influenced by many different factors and therefore accurate measurement of PMD should be done in all phases of building and operating optical path.
