1 Introduction 1.1 What is FSO? FSO is free space optics provides point-point broadband communications using Laser Light as the transmission medium. FSO is a state of art data communication method which is based on a very old communication solution. Ancient Chinese developed a protection system against the Mongol tribes, building watchtowers within the line of site to other towers.
very hard receiver sensitivity. These two factors combined to provide one of the best performing FSO systems on the market today. To meet the demands for every higher bandwidth, GeoDesy FSO continues to invest heavily in research and development with the newest product line which offers Gigabit speeds being launched. This manual describes the GeoDesy FSO series of free space laser transmission system.
1.3 Optical Free-space Transmission The principle used in free space laser transmission is very similar to the one is used for fibre optic transmission. The difference is while fibre optic devices use electronics and optics optimized for transmission to the air. Also one can observe to the similarity in the transmission properties. No galvanic contact, no ground-loops, no need for surge protection, noise immunity, long distances, high bandwidth.
1.4 Typical applications Most typically the GeoDesy FSO Next product are is used to interconnect LANs. The system is protocol transparent, thus other applications also can be taken into consideration. Appropriate interface converters are needed and system bandwidth must be matched for that. Here we collected some circumstances, where the deployment of the GeoDesy FSO is the most adequate as a cost effective solution.
2 Interfaces for the Giga Next Series 2.1 1000Mbps TP interface The GeoDesy FSO series products are designed to provide easy-to-use and costeffective solution for interconnecting Local Area Networks. By utilizing standard Category 5e cable and using standard IEEE802.3af interface the deployment of the system is easier than ever before. The transparent and wire speed data transfer together with virtually zero latency assures the easy integration of the system in all environments.
3 Sites of installation 3.1 Key factors of operation There are four key issues that the site survey has to shed light on. Proper system operation cannot be guaranteed without satisfying all of the four requirements. Clear line of sight - The entire optical path between the two ends must be free of any obstacles. It not only means that one has to see the other side, but other possible sources of disturbance should also be taken into consideration.
Preferred installation Pay attention to sites Avoid (*) Concrete wall Brick wall Soft materials Chimneys Wooden constructs Metal masts or Frames Hidden heat isolations, like Styrofoam Behind window Old constructs Microwave towers (*) In cases where installations are listed under “AVOID” cannot be avoided than special mounting accessories to be designed and special installations must be used. It is not only the building that has to be solid, but the support structure too.
3.3 Distance measurement Because the units were designed, and calibrated for certain distance operations the higher distance will decrease the availability. GeoDesy FSO pre-calibrates and pretests every unit shipped to the customer. To ensure that the unit you are about to buy fits to the needs, the first step is to measure the distance. The best way to measure it is by GPS (Global Positioning System), these units are accurate enough to determine the distance between two points.
4 Eye safety There are no two installation spots of the same kind, the buildings or structures, the available space and the accessibility of the place will be different in each case. Nevertheless, as a general rule it is very important to select the installation site so that nobody can look directly into the transmitter.

7 System installation 7.1 On the table test Warning! Do not look either into the transmitter or the receiver optics because at this distance even the reflected laser beam can be dangerous to your eyes. Operating the system on much shorter distance than presumed originally can cause saturation or even permanent damage to the receiver. Always use optical attenuators for this kind of test. The on-the-table test needs careful planning and careful use during the test period.
7.1.1 Alignment of the AT-2400E1000TP The first step after the unit was placed to the bracket, and the units facing each other. On the back of the receiver you can find the LEDs and LCD screen for the local received level and the remote received level. This help will be very useful because as soon as you have received – which is very easy to achieve – you can see the effect of your local sides movement to the other side.
