2 Introduction 2.1 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 GD series of free space laser transmission system.
2.2 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.
2.3 Typical applications Most typically the GeoDesy-FSO-TP is used to interconnect LAN-s. 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 employment of the GeoDesyFSO is the most adequate and cost effective solution.
2.4 About Geodesy GeoDesy FSO is part of the GeoDesy Group, with main focus on high speed wireless communication, especially laser-based Free Space Optical (FSO) transmission.

6 Sites of installation 6.1 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.
6.2 Preferred installation sites All buildings and constructions have a certain movement of their own. It’s determined by the structure and material of the building. Metal structures can shift or twist due to temperature changes. Wooden construction can expand or shrink with any changes in humidity. Give preference to concrete or brick buildings. On the other hand high structures like towers, skyscrapers or poles are always subject to movement.
6.3 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.

• Power up the heads! Receiver Alignment • After a few seconds unplug the plugs of the motor controllers on both sides! The motor control is a “light-buffer” this saves the power for the bad weather and in the same time protects the receiver against overload. During the alignment it can be used manually, to avoid the saturation, and keep the detector voltage on the level where it can be still monitored.
The receiver alignment should be done on both sides; the requirement is some incoming light from the remote side (at least receive). This alignment will determine the position of the head and in the head the position of the receiver. The idea is similar to the focusing, but the only way to find the focus is to move the head. You can check the incoming light efficiency in two ways. Once you can use the LEDs of the receiver.
Beam Alignment • • • Switch off all of the transmitters on both sides. Switch on one of your transmitters on one side. Move the beam to the middle of the remote head. You can move the beam with the screws on the back of the transmitters. The directions of beam moving in the function of the turning direction of the screws can be seen on the figure. You can check the position of the beam using a digital camera with infrared lenses.
Set the beam size You can set the beam sizes of each transmitter separately. So do not switch on more than one transmitter in the same time! You can set the beam size turning the focusing tube. First you have to loose the shipping screws which are functioning as transmitter fasteners, during shipment. Then you have to loose the locking ring which fastens the focusing tube. After that you can manipulate with the beam size turning the tube.
9.2.5 Connecting to your Network If you have a TP head You can find a TP connector unit in your ODIU, with there connectors. You have to plug in the TP cable of your head into the RJ45 connector.

Receiver Alignment • After a few seconds unplug the plugs of the motor controllers on both sides! The motor control is a “light-buffer” this saves the power for the bad weather and in the same time protects the receiver against overload. During the alignment it can be used manually, to avoid the saturation, and keep the detector voltage on the level where it can be still monitored. The detector voltage can be increased to seven volts; above seven volts you won’t be able to monitor the detector voltage.
Beam Alignment • • • Switch off all of the transmitters on both sides. Switch on one of your transmitters on one side. Move the beam to the middle of the remote head. You can move the beam with the screws on the back of the transmitters. The directions of beam moving in the function of the turning direction of the screws can be seen on the figure. You can check the position of the beam using a digital camera with infrared lenses.
In every transmitter there are two shipping screws against the bigger moving of the tube. These screws allow only less movings for the transmitters, so if you need bigger moving you have to pick them out first. Anyway, GeoDesy-FSO strongly recomends that you take all of them out first… Set the beam size You can set the beam sizes of each transmitter separately. So do not switch on more than one transmitter in the same time! You can set the beam size turning the focusing tube.
You can measure your beam size using a digital camera with infrared lenses. With this you can see the beam behind the head on a surface (for example on a wall) and there you can measure it. In that case if there are not any surfaces for beam measuring, you can do it in the following method: Face the remote side and check the beam with your camera. Move slowly to the right in straight line until the picture of the beam, what you see in the camera, is reducing, and sign that place.
If you have a TC head You can find a two sided fibre connector in your ODIU. You have to connect the fibre cable of your head into the one side of the connector, and into the other side you have connect the fibre cable of you network equipment (switch; router or GD combiner). The fibre plugs of the heads are always SC typed, which means that them cross-sections are cubic form. The fibre connector in the ODIU is SC-SC typed, so you have to provide an SC fibre plug for you network.
If you have a TC head Using the RJ11 Sevice Connector and the two green connectors you can connect your management indoor unit to the head. The necessary signals can be found on the blue and blue-white wires of the head power cable. You have to connect these two wires into two pins of the four of the two green connectors. These pins are connected to the pins of the RJ11 Service Connector.
Outdoor interconnection unit with Heater As an optional glass heater can be ordered for the link, the idea is the same what is used for the cars back window heater. This automated heater turns on and removes the ice from the front window only below 5 ºC(±2ºC). It turns of only if the temperature goes above 10ºC. If the heater is in use you will see a small yellow LED lighting on the power circuit board.
9.5 48 VDC Power supply connections In fact the 48VDC power supply is optional; the connection is almost the same. In the case of the 48VDC power supply it is important to pay attention to the polarities. The wrong polarity of the cables can damage the power supply. In this type of ODIU you can find fuses only on the primarily side of the transformer.
