In this article the composite author dealt with measurement possibilities of polarization states of light source emitting 1550 nm which was affected by atmospherically transmission environment in special acrylate box 2.5 m long. The Polarimeter Thorlabs TXP 5004 and the External Sensor Head PAN5710IR3 measured the changes of polarization parameters, ellipticity and azimuth, defining placement on the...
This article aims for meeting with influences of the atmosphere on real professional Free-Space Optical (FSO) link. Atmospheric effects could cause a degradation of quality of FSO communication and of received optical beam in shape of decreasing of optical power value through parameter RSSI (Received Signal Strength Indicator). Finally, this could even lead to communication loss. The article focuses...
Free Space Optics (FSO) is a data transmission technology using an optical beam going through the atmosphere. This communication technology has several indisputable advantages but also disadvantages. The one of the disadvantages are the thermal turbulences. This paper deals with the artificial thermal turbulences which affect the optical beam going from the commercial FSO head. The new against articles...
This article deals with problem of thermal turbulence effects created by direct heaters on optical link which used OOK modulation for communication. For the purpose of uniform conditions of thermal turbulences with speed of 3.5 m·s1 and temperature 48 °C the special laboratory box was made. On the transmitting side the bit rate (0–160 Mbps) of optical link was changed and on the receiving side was...
