Add to ORKGThis thesis is aimed at section of transmission of digital data by using two optical wireless communications realized by two free-space optics transcievers working in full-duplex mode. Generally, the work describes present options of optical connections, their principles and comparison with other connections. Basic components of realized transmitter and receiver are mentioned with their characteristics and wirings. The work describes options of transmission and further deals with various external events, which influence characteristics of transmitted optical signal. Thesis describes the optical part of design and construction free-space optic and it’s ending energy balance of this link. Further, the work treats of basic use of ethernet tech...
