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. 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
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.
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
FSO systems use a laser-diode as a light source,

very hard receiver sensitivity. These two factors combined to provide one of the best
performing
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.
The GeoDesy-FSO GD 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 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.
GeoDesy-FSO GD systems comprise two laser-heads and the two indoor
The
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.

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.
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 laserdiode. 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

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 GeoDesy-
FSO
is the most adequate and 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.

outstanding system availability figures. The transparent and wire speed data transfer
together with virtually zero latency assures the easy integration of the system in all
environments. Furthermore, PRONTO series systems can be ordered with IP based
SNMP compatible device management that allows remote control and monitoring of
the equipment. Because they use infrared light as transmission medium,
GeoDesy-FSO systems do not require frequency licenses and the transmission is
not affected by electro-magnetic interference. The concentrated laser beam is
extremely hard to tap, even to discover since it cannot be detected by spectrum
analyzers. Basically, a GeoDesy-FSO link can be considered as a virtual fibre in
the air.
The GeoDesy-FSO PRONTO systems comprise of two Laser Heads (each
containing two transmitters), two Outdoor Interconnection Units (ODIU) and two sets
of interconnection cables — one at each end. The Laser Heads are installed
outdoors, where a clear optical path exists between the two sites. Each head is
equipped with heavy duty Alignment Base Unit, which allows exact positioning and

ensures reliable long-term operation of the system. The head assembly features rear
and front doors that provide easy access to the internal parts on the field during
installation, troubleshooting or upgrade procedures. Next to the head the Outdoor
Interconnection Unit provides fast and easy interconnection between the laser head
and the cable coming from the network equipment. Moreover the ODIU houses the
Power Supply Unit (PSU) of the system and the network interface. The PSU
provides the low voltage power required to operate the laser head while the data
port offers direct connectivity for standard network equipments. A variety of standard
copper and fibre interfaces are available for voice and data applications. The system
contains built-in signal monitoring unit, which features a visual signal strength
indicator and LINK status information accessible on the rear of the head assembly.
The optional IP Based Management Hardware is placed in an Indoor Interconnection
Unit (IDIU). The bar graph of the IDU displays the actual signal strength level while
the LED indicators show the presence of Minor or Major alarm condition. With the
help of the relay contacts an external alarm monitoring equipment may be connected
to the system to process the alarm signals further .In addition to the above
GeoDesy-FSO GDViewTM software allows the monitoring of the link’s operation
through a proprietary graphical interface (GUI) via Ethernet or RS-232 ports or a
third party SNMP manager via TCP/IP connection. .
Industry standard network interfaces and clear upgrade path for higher bandwidth
protect the customer's investments in GeoDesy-FSO systems. Moreover,
PRONTO systems offer high level of network flexibility due to their modular design,
which makes them ideal to follow network topology changes.

equipped with heavy duty Alignment Base Unit, which allows exact positioning and
ensures reliable long-term operation of the system. The head assembly features rear
and front doors that provide easy access to the internal parts on the field during
installation, troubleshooting or upgrade procedures. Next to the head the Outdoor
Interconnection Unit provides fast and easy interconnection between the laser head
and the cable coming from the network equipment. Moreover the ODIU houses the
Power Supply Unit (PSU) of the system and the network interface. The PSU
provides the low voltage power required to operate the laser head while the data
port offers direct connectivity for standard network equipments. A variety of standard
copper and fibre interfaces are available for voice and data applications. The system
contains built-in signal monitoring unit, which features a visual signal strength
indicator and LINK status information accessible on the rear of the head assembly.
The optional IP Based Management Hardware is placed in an Indoor Interconnection
Unit (IDIU). The bar graph of the IDIU displays the actual signal strength level while

2.7 GeoDesy-FSO GD5000 series
The
GD-5000 series products from GeoDesy-FSO
are laser based free space optical systems designed to
provide flexible, reliable and secure solution for high
speed wireless connections up to 5000 m. Due to their
modular design the equipments are easy and fast to
troubleshoot and upgrade on the field. Adjustable
transmitter optical system allows custom configuration of the system for specific
installations. The patented Aperture Control Mechanism delivers outstanding system
availability figures. The transparent and wire speed data transfer together with
virtually zero latency assures the easy integration of the system in all environments.
Furthermore, GD-5000 series systems can be ordered with IP based SNMP
compatible device management that allows remote control and monitoring of the
equipment. Because they use infrared light as transmission medium, GeoDesy-
FSO
systems do not require frequency licenses and the transmission is not affected
by electro-magnetic interference. The concentrated laser beam is extremely hard to
tap, even to discover since it cannot be detected by spectrum analyzers. Basically, a
GeoDesy-FSO link can be considered as a virtual fiber in the air.

3 Product grouping by interface type
3.1 100Mbps TP interface
The GeoDesy-FSO TP 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 100BaseTX interface the deployment of the
system is easier than ever. The transparent and wire speed data transfer together
with virtually zero latency assures the easy integration of the system in all
environments.
TP systems should be considered as repeaters in the network. So the
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.
The TP system layout
The head needs a power and data cable, which is connected to the ODIU (Outdoor
Interconnection Unit). The required power for the outdoor unit is 230VAC or
115VAC, depending on the order. Please note that the transformer is not a switching
mode power supply, so has to be configured for the proper voltage before
connection, this has to done before shipment. The heads are fixed 100Mbps and are
auto-negotiating.
