The article presents state of work in technology of free-space optical communications (Free Space Optics − FSO). Both commercially available optical data links and their further development are described. The main elements and operation limiting factors of FSO systems have been identified. Additionally, analyses of FSO/RF hybrid systems application are included. The main aspects of LasBITer project related to such hybrid technology for security and defence applications are presented.

“…Signal amplification and some processing is needed to convert the signal from uplink frequency to down link frequency. Many studies were done with different methods such as RF link budgetSimulink -MATLAB, which shows the effects of the power level, antenna gain and S/N ratio only [1]. RF-café offers a program named RF calculator workbook by excel, and it deals with main factors of the link budget and calculates the power received [2].…”

In this paper, a satellite link budget calculator was done by using MATLAB -GUI program, the link budget is represented in one active screen, and it is designed to show the parameters that affects the RF signal when it is passing through the three main parts of the satellite communication system and regardless of the input signal power level. The results of the link budget program with the effects of changing the parameters will be shown inside the same active screen, which makes the users (students and trainers) analyze the reason that causes the weak signal when it reaches the satellite receiver.

“…FSO communication using high bandwidth transmission links has enormous potential to serve for requirements of high data rate transmissions. License free bandwidth, high carrier frequency (range 20 THz-375Thz), easy deployment, appreciable security of data, avoiding electromagnetic pollution, low power consumption enables FSO links to provide high data rates communications [1]. Its various advantages over existing Radio Frequency (RF) technologies like wider bandwidth that can support a large number of users without any delay or interference in communication, have increased its demand in the market.…”

Abstract-Free-space optical (FSO) communication is a cost effective and high data rate access technique, which has been proving itself a best alternative to radio frequency technology. FSO link provides high bandwidth solution to the last mile access bottleneck. However, for terrestrial communication systems, the performance of these links is severely degraded from atmospheric loss mainly due to fog, rain and snow. So, a continuous availability of the link is always a concern. This paper investigates the dreadful weather effects such as rain, fog, snow, and other losses on the transmission performance of FSO systems. The technique of using an array of receivers for improving the performance of FSO links is explored in this paper. It involves the deployment of multiple photo detectors at the receiver end to mitigate effects of various weather conditions. The performance of the proposed system is evaluated in terms of bit error rate, received signal power, Q-factor and height of eye diagram. The influence of various weather conditions of plain and hilly areas are taken into consideration and results are compared with conventional FSO links.
