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. And as

soon as the towers saw some hostile sign on the horizon they use they shield to

reflect the sun to the remote towers. In this way the area could be prepared against

the attack in a very short period of time.
In the ancient times for this communication use the mirror

as a transmitter and the sunlight was the light source, and
the receiver was the remote guard’s eye. This basic
signalling method was developed later into up
communication device which used „line coding”. This
allowed the guards to tell the number of enemy, or the
direction they are coming from.

Current FSO systems use a laser-diode as a light source,
and a receptor diode (photo diode) to receive the signals
coming from the laser diode from the transmitter side. But
the basic elements are still the same: line of site between

the communication nodes, and individual line coding. It is all about performance.

GeoDesy FSO offers FSO systems with the highest power budget available on

the market.

1.2 Why is it important?

Because of in the ancient Chinese times, the rain, the fog, or even the cloudy

weather, could impact the operation of the whole system.

In the FSO units, comprising light source and receiver the cloud problem was

solved, but development conditions still can impair

performance. To go throw the rain, the fog, or snow you

need more and more power to be seen from the remote

side. Achievable power levels are limited by a number of

factors including eye safety.

In this way there is no other choice to see more than

„training the eye”. Making the receiver more and more

sensitive to sense delight emitted from the remote side.

GeoDesy FSO offers high transmit power and also

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.

The GeoDesy FSO Next product range offers cost effective reliable free space

laser transmission for two Mbps up to 1000 Mbps data to the air, where a clean line

of site is available. It delivers the most effective point-to-point connection between

computer networks or telephone exchanges.

No need for installing cables, no rental costs, no licensing requirements.

Ideal for urban areas or city centres, where the use of these lines are expensive.

Suitable for factories or industrial environments where high noise level can interfere

with the transmitted data. The best choice to make a connection across rivers and

other natural or artificial obstacles, where cable is not available.

The transmission technique used in the GeoDesy FSO devices provides

transparent and wire-speed data transfer with virtually zero latency. Because they

use infrared light as the transmission medium, GeoDesy FSO system do not

require frequency licenses and the transmission is not effected by electro-magnetic

or radio-frequency interference. Basically the GeoDesy FSO link can be

considered as a virtual fibre in the air, which ends in real fibre optic cable at both

ends.

Our product is built using high quality components for operation in even the most

adverse conditions.

Metal housing gives robust, waterproof environment for the electronics.

The shield protects the device from direct sunlight and provides extra air isolation.

The GeoDesy FSO X systems comprise two laser-heads and the two indoor

interconnection units (OIU) - one at each end. The interface connections are housed

in the outdoor unit together with the PSU of the system.

Best practises were employed in cost engineering throughout the development of

GeoDesy FSO.

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.

What makes it unique – and difficult to design – is that it does not require any

transmission medium like fibre or copper, but it has to cope with the dynamically

changing parameters. For instance while the attenuation of an optical fibre is

constant, the attenuation of the atmosphere between the laser units can change

dramatically (depending on the weather conditions).

The laser-heads are usually placed on top of building, where the clean line of site is

guaranteed and the beam cannot be interrupted.

In the head the incoming signal is amplified, encoded, and then drives the laser-

diode. The transmitter optics assures the proper beam shape and controls the beam

divergence. The receive optics perceives and directs the transmitter signal to the

photo diode. The diode converts it back into electrical, than it is decoded, amplified

and converted.

There are several things that can influence the quality of transmission. We can

classify those factors into three main groups.

System conditions - transmitting power, transmitter’s wavelength, beam divergence,

receiver optics diameter, receiver sensitivity, parameters of optical system and

casing. These parameters determine the system’s characteristic at a certain

distance and are controlled by system design and factory set up.

Weather conditions - molecular absorption, particle scattering and turbulence. These

elements have great effect on the operational conditions of the system. We do not

have very much influence on them; proper product selection can eliminate the

undesirable effects.

Environmental conditions - building movements, direct sunlight, refractive surfaces.

These are also key factors related to the installation sites and can be controlled by

appropriate site survey and system installation

LAN

ISP

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.

Those are:

Areas with natural or artificial obstacles

Where cable is actually not an alternative, like across
rivers or railways or in rugged terrain.

Urban areas

Where only leased lines are available with

limited speed, and high rental cost. With

GeoDesy FSO links you can establish on line

LAN-to-LAN connections.

Industrial areas

Where you have noisy environment with high EMI or
RFI. Factory buildings, airport objects can be
connected through laser link.

ISP connections

Where high bandwidth is required. ISP’s can offer

high-speed links to their customers or trunks can be

established between ISP’s instead of expensive leased lines.

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. The transparent and wire

speed data transfer together with virtually zero latency assures the easy integration

of the system in all environments.

The X PoE systems should be considered as repeaters in the network. So the

installation distance between the head and the network device is 100m. The

distance on a back to back site is maximum 5 meters, between the heads without

signal regeneration.

The X PoE systems connecting to the network with an RJ 45 cable which provides

the power required for operation and the data. The system requires IEEE 802.3af

Power over Ethernet switch or power injector. The power consumption suits to the

standards described in the standard. Also provides fast and easy connection for the

management system for more details please see the chapters below. The system is

certified Class 1M product, this way 100% eye safe.

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. For

example there might be turbulence above the roofs and other constructions, and this

can cause fraction or scattering of the beam or snow accumulation on roofs too

close to the beam can influence or even interrupt communication.

Solid mount surface - is the key for long-term operation. Since the diameter of

the beam is limited, it is extremely important to mount the unit on a stable structure

with the possible smallest movement. This way the receiver of the remote unit

cannot get out of the beam due to the movement of the opposite head.

East-West orientation - although the receiver optics are equipped with optical

filters to protect the receiver diode from the effect of undesired light sources, direct

sunshine can cause saturation of the diode. This prevents the system from working

properly for several minutes a day at certain times of the year. In most cases this

effect can be avoided by careful selection of the mounting spot.

In order to comply with the requirements of the successful installation - including the

discussed four key factors and other criteria - the following matters should be taken

into consideration.

3.2 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. Mount the support frame to walls of the building or near corners, as they

are the most stable spots. Use appropriate consoles for wall mounting. If a stand is

used on the top of

building, secure it directly to the ceiling or to the concrete cornice 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. Another important consideration is to provide enough space

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.

Preferred installation

Pay attention to Avoid (*)

sites

Concrete wall Behind window Soft materials
Brick wall Old constructs Chimneys
Microwave towers Wooden constructs
Metal masts or Frames
Hidden heat isolations,

like Styrofoam

(*)

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. Antenna

poles and security camera holders are not suitable for the GeoDesy FSO units.

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 pre-

tests 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.
For more details
please refer to the
GPS manufacturer
handbook. Also there are several
other ways to measure the
distance. If you know the exact

address you can use mapping software like MapPoint or Auto route.

3.4 Direct sunshine

To prevent the sun

shining directly into the

receiver optics, first one

has to determine the

orientation of the link.

Try to avoid East-West

orientation wherever it

is possible. Examine

both sides of the link at

sunset and sunrise and

find a position where

the sun cannot get

behind any of the heads. Be aware that the path of the sun is changing throughout

the year.

INVISIBLE LASER RADIATION

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. For this reason place the head

either so high (on the side wall of the building) or so close to the edge of the building

(on a parapet on the rooftop) that no person can approach it accidentally and can

get into the beam path. Set up barriers if necessary and put warning signs at

prominent places.

The laser heads are provided with all labels and hazard warnings required by the

laser standard. There are warning labels on both the left and right side of the

protective cover next to the optical window and there is a warning and an informative

label on the rear side of the laser head.

6 System installation

6.1 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.

The units should be placed at about 2 m distance from each other with optical

windows facing one another. Put an appropriate optical attenuator (Attenuating foil

or cardboard with several small holes) between the heads. Make all the necessary

connection as described below to connect your network equipment (computer or

protocol analyzer) to the heads and power up the units. Turn ON the Poe injector

and check if the power LED is ON on the head.

You should be able to align the units without any tool and get full received level on

the signal strength LED’s. Make sure that the “Saturation” indicator is OFF. Adjust

your attenuators if necessary to avoid saturation of the receivers.

Please note that at this short distance, specially the longer distance links can reflect

to the remote site or even to the same head. If you experience full receiving level,

with no traffic throughput, in that case try to move the heads slightly units out of the

reflection zone.

Please also take in consideration that the laser beam is concentrated and in such a

short distance can harm your eyes, every time you test the units on short distance,

do it with extra care. Never look into the sighting device if the remote laser is turned

on. We strongly suggest to double check the power connection before you turn on

the device. Handle the power connection with extra care. Safety first.

After obtaining the desired received level, check the data connection between

devices. Using computers or appropriate testing devices.

On the table tests are perfect for troubleshooting (If there is a transmission problem,

check the status of the connecting devices (e.g. Link signal or cable polarity) and

cables.) in a controlled area. If you experience some problems during the test,

please try to test the connected equipments with a direct connection.

6.2 AF adjustment method

What is AF after all? AF stands for Auto Focus. Geodesy FSO Pinto Next AF

is equipped with the lates innovation from Geodesy. An automatic focusing control

system. The system is capable of changing its beam divergency depending on the

changes of the environment. In the case if the weather gets bad, the system will

decrease the beam size, to concentrate the distributed beam power, to ensure more

stable operation.

IMPORTANT! Auto focus adjustment does not work if there is no remote level!

Remote connection required for the Auto focus adjustment.

The installation of the Pinto Next AF is pretty much the same as the standard

system installation. To make sure that the AF system won’t kick in during the

alignment, ensure that the AF is set to disabled, which is the factory default.

The default settings of the Auto Focus (AF) laser heads is manual mode (disabled).

The factory beam divergence is set for 750m, this way the alignment of the system

will be easy on every installation distance.

Please do not change the setting of the AF laser heads to auto focus when there is

no connection between the two heads.
