Horváth Holding Investment PLC. 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.
Horváth Holding Investment PLC. 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 (Europe) Limited 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 Next series of free space laser transmission system.
Horváth Holding Investment PLC. 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.
Horváth Holding Investment PLC. 1.4 Typical applications Most typically the GeoDesy FSO Next products are 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 deployment of the GeoDesy FSO is the most adequate as a cost effective solution.
Horváth Holding Investment PLC. 2 Interfaces for the X Series 2.1 100Mbps TP interface The GeoDesy FSO X PoE series products are designed to provide easy-to-use and cost-effective solution for interconnecting Local Area Networks. By utilizing standard Category 5 cable and using standard IEEE802.3af interface the deployment of the system is easier than ever before.
Horváth Holding Investment PLC. 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.
Horváth Holding Investment PLC. for alignment and to have the potential for future maintenance. Consider that the support frame is usually heavy, so the selected spot should be easily accessible.
Horváth Holding Investment PLC. 3.3 Content of the package Laserbit provides three product range with three different kinds of package contents. The Laserbit Pluto Mobility(comprising Pico, Pinto and Pronto links) has all the necessary nuts, bolts wall plugs and for the easy installation of the link. Also you can find in the package the power supply units. These units also have all the necessary gadgets for the fastening.
Horváth Holding Investment PLC. 4 Sites of installation 4.1 Key factors of operation Pluto Mobility was designed to cover only about 20 meters with a wide transmitter beam; the following should be taken into consideration, to decrease the factors causing inconveniences during every day use. 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.
Horváth Holding Investment PLC. wherever is possible. Do not fix stands to insulating materials as they can slowly sink under the weight of the unit and with temperature changes. Big chimneys and smokestacks may look stable, but as their inner temperature varies they can also move. Vibration caused by heavy traffic, trains and elevators etc. may slowly move the system out of its specified direction.
Horváth Holding Investment PLC. 5 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.
Horváth Holding Investment PLC. 6 The mounting bracket In the following chapter you will find detailed description of the bracket fastenings. Pluto Mobility was designed to be used for high speed data transfer, on short distances. The unit provides Point-to-point connection at the speed of 100Mbps, and a POE interface. The bracket was designed to fulfill these requirements. The horizontal movement of the link is fixed with the hand-knob.
Horváth Holding Investment PLC. 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.
Horváth Holding Investment PLC. 7.1.1 Alignment of the heads To make the alignment easier, we have equipped the unit with an audio aiming tool, and a laser pointer. These tools will help you with small beep signals, and laser light to confirm the alignment. Audio Alignment tool The Audio Alignment Tool, when you first power up the unit will give one second long beep. That means that the unit has booted up and ready for operation.
Horváth Holding Investment PLC. Link alignment The sheet below is a quick overview table of how the alignment steps following each other. Pluto is only 20 meter distance, however the installation, is still the same as for the longer distance units. Only one head should be moved at the time. Moving both units will make confusion and make the installation time longer.
Horváth Holding Investment PLC. How to set up the link using a laser pointer Place a piece of paper in front of your local unit. Direct the pointer beam from the remote end to your local unit Keep on directing the remote pointer beam closer to your local pointer beam. Set the remote beam center to your local beam. Repeat these steps on the remote end as well. Check the receiving level, and with smooth movements you can fine tune the unit, further more.
Horváth Holding Investment PLC. 7.2 Meaning of the LEDs FO Link: Fibre optical link between the two heads. TP Link: Copper link between the head and the Network equipment. Level 1: 25% of the total (acceptable by the receiver) incoming power It indicates after 25µW incoming light efficiency. Level 2: 50% of the total (acceptable by the receiver) incoming power. It indicates after 50µW incoming light efficiency.
