This diploma thesis first handles the general issues concerning free space optics in the~atmosphere. The aim is to design and implementation of optical wireless equipment, which would serve in the laboratories of optical networks. Ronja was used as the basis for a~wireless link, which is already widespread in the world. Students will work with the device, which they may come into contact in the future. It consists several separate modules: transmitter, receiver and inteface. Each module have a separate chapter describing the~functional blocks and circuit realization. Ronja was adjusted for the needs of~laboratory tasks, where additional voltmeters measures received signal strength (RSSI) at~both ends of the link. Measuring device provides adjustment of power the transmitting LED via~computer, measures and sends RSSI values to a PC via~USB or RS232, turn off Ronja with computer. For targeting the pipes of Ronja was developed the mechanical design. In the last part of thesis the device was undergone a series of tests.
