The main driver for the development of wireless optical communications is to increase the bandwidth of wireless channel. In the optical range this can be achieved by relatively simple means, using widely used in fiber-optic technology wavelength division multiplexing (WDM). The efficiency of the specified decision is promoted also by the fact that practically all components for narrow-band transmitters and optical filters are present at the market for fiber optic applications. The challenge is how to integrate these components in a wireless optical channel. The aim of this work was to verify the possibility of using WDM technology in the atmospheric channel, which is characterized by a high level of turbulence. Atmospheric turbulence leads to significant signal reception instability unlike fiber-optic communication line. In this article the research results of solutions for the transmission of 4 Ethernet 10 Gbps streams via the atmospheric channel at different distances are given. Equipment for research was built on the basis of serially produced Artolink M1-10GE model which provides 10 Gbps data rate on a single wavelength in the initial configuration.
Key words: Wireless Optical Communication, 40 Gbps wireless, Free Space Optics, optical communication terminal, MANET, wavelength division multiplexing (WDM), high-speed secure communication channel.
