In relation fog, rain, and haze are atmosphericĪttenuation it's important to be taken into account of FSO system.įog is the most serious attenuation for FSO system due interaction : divergence angle (in mrad), R: range link (in km), :Ītmosphere attenuation. Where : received power, : transmitter power (inĭBm), dr & dt the received and transmitted aperture (in cm), In FSO communication system design which has equation must beĬonsidered to collect better result. Section4, about result and discussion, and section5, is the conclusion. The arrangements of this paper are, in section2,Įxplain mathematical consideration, section3, illustrates Ro-FSO design, Investigations for first time the radio frequencies by carrying 2.5 GbpsĪnd 10Gbps data rate over maximum link of FSO under clear air and heavyįog weather condition. Power exhaustion, high band width, low attenuation, and without need of Specification, it ability of send RF signals on optical carrier with low Problems removing RF spectrum overcrowding in current wireless networkīy placed RF signals on optical wave. Transmission distance while low frequency signals has lower losses made However, the high frequency signals facing more loss which reduce the Highest frequencies, which increasing the ability of carrying data rate. Wireless communication network called millimeter wave (mm-wavelength) (3kHz_300GHz) range that RF system could operate. (RF) is an electromagnetic wave system that used in communication Variation due to random changing in temperature and pressure leading toįading of transmission path called scintillation. The atmosphere turbulence is a refraction index RF system the rain is the major source of attenuations reach Source of attenuations in Austria fog attenuation reach (up to 100ĭB/km). Very sensitive to weather condition which is (atmospheric attenuationĪnd atmospheric turbulence). Their (FSO) advantage there are some flaws that prevent its development.įirst, the line of sight (LOS) in transmission signal. Of optical fiber to save time and cost over long distance. FSO consist many advantages which are high security, broadīand capacity, unlicensed operation, and low cost. Light in open air instead of glass or other medium from one point toĪnother.
