Abstract: [cze] [eng]
Práce se zabývá elektronickou digitální jednotkou pro přenos ultrapřesných optických zdrojů frekvence po optických trasách, softwarem pro její obsluhu a konfiguraci a příklady jejího možného praktického využití. This work presents a digital electronic unit for control and stabilization of coherent laser systems intended for the transfer of ultra-precise optical frequency signals. The device, based on a digital signal processor, enables phase noise detection and compensation, control of DDS and DAC components, and flexible configuration using digital filters and PID controllers. It is designed for applications in optical transmission links, such as phase noise suppression and optical repeater implementation. The system also includes user software for real-time monitoring, analysis, and configuration of the device.\n
