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 FSONext series of free space laser
transmission system.
The GeoDesy FSONext 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 FSOX 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

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 FSOX 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.

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

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.

Alignment steps
1. using the crosshair align the units into a roughly aligned position. Please note
that the alignment scope will not be able to provide with a perfect alignment,
this will have to be done using the fine alignment screws referring to the
received level screen on the LCD panel.
2. using the fine adjustment screws on the alignment base set the units to the
highest received level possible. (for further details on how to perform the fine
adjustment refer to 6.2.1 and 6.2.2 chapters)
Default distance setting of all Pinto Next AF laser heads for 750m. As you can
see in below sketch, “+25 STEP” equals ~ 2 cm larger laser beam over 100 meters.
For example, if you would like to install the laser heads over 350 meters than you
will need smaller beam size to reach bigger distance (compared to the default
750m), so click on “-100 STEP” which will make the laser beam narrower and will
be proper for 850m. While clicking on the “STEP” buttons please check the remote
received level on the laser head.
Please perform the same operation on the other side.
3. After we have got the proper level, please click on “Save position as default”
button. As you have clicked on the “Save position as default” button the laser
heads will enable the AUTO FOCUS mode (enabled). The equipment will
automatically improve the remote level to the most ideal position.

Keep on moving to determine where the core part of
the beam is. This can be done easily by looking at
the received level you will see that the received level moves up then it will start move
down than up again. During this time you just had the head moving into one direction. If

Head Serial Number: This is the head serial number and during the Activation
process we will ask for this number.
Status info screen
Clicking on the Device Setup you will enter the main status information screen,
which will give you good summarized information of the device, such as status
information of the transmitters, detector level, or temperature values.
Laser ON: Transmitter transmitts
Laser OK: Transmitter works properly, transmitts and the transmitted signal is valid.
Temperature: ambient temperature inside the device. These units were designed for
extreme conditions and should not have any problems under -20C to 70C. In fact the
unit is emitting some heat so the temperature displayed is not the air temperature
outside the head. For example the temperature can be -10C outside but in the
device it wont go below -1 or -2. The value will display error depeding on the setting
was done device setup. There is no default value for this setting, only a suggested
value, which is 60C.
Detector level: shows the local heads received level. In volts, the maximum is 7 volts
and the minimum is 0.2 volts. The value will display error depeding on the setting
was done device setup.
Remote Detector level: this value is dispalyed form reception of the remote head.
The maximum is 7 volts and the minimum is 0.2 volts.
TP_Link: displays that there is connection over the TP cable.
FSO Link: displays that there is valid signal received from the remote end.
Remote is visible: this status information is a good information about the connection
over the two laserheads if this status is OK that means that there is data transferred
over the link.
Remote TP Link: shows that whether the remote end is connected into the switch
and the TP interface is available.
PSU: The PSU of the device is sending the OK signal.

MGM Trusted-host filtering: Here you can adjust two addresses wehre you can till in
from which computer with you reach the MGM! To adjust you will hove to adjust a
filter.
Filter adjust:
Off: Turned off.
IP: Only see the IP address.
MAC: Only see the MAC address
IP+MAC: Either IP or MAC address should be equal to the adjusted.
IP&MAC: Both IP and MAC addresses should be equal to the adjusted.
Network statistics page
As a new feature of the Next series of products, you can monitor the live traffic flows
over the link. These figures are showing the reception on a port of FO(fibre optic
from the remote end) or TP(Twisted pair, form the local connected equipment).
Unicast: sending of information packets to a single destination
Multicast: is the delivery of information to a group of destinations simultaneously
using the most efficient strategy to deliver the messages over each link of the
network only once and only create copies when the links to the destinations split.
The word "Multicast" is typically used to refer to IP Multicast, the implementation of
the multicast concept on the IP routing level, where routers create optimal spanning
tree distribution paths for datagram sent to a multicast destination address in real-
time. But there are also other implementations of the multicast distribution strategy
listed below.

Broadcast: refers to transmitting a packet that will be received (conceptionally) by
every device on the network. In practice, the scope of the broadcast is limited to a
broadcast domain. Not all computer networks support broadcasting; for example,
neither X.25 nor frame relay supply a broadcast capability, nor is there any form of
Internet-wide broadcast. Broadcasting is largely confined to local area network
(LAN) technologies, most notably Ethernet and Token Ring, where the performance
impact of broadcasting is not as large as it would be in a wide area network. Both
Ethernet and IPv4 use an all-ones broadcast address to indicate a broadcast packet.
Fragments: datagram can be fragmented into pieces small enough to pass over a
link with a smaller MTU than the original datagram size.
Jabber: transmission of a packet on a computer network that is larger than the
network's MTU. Such transmissions hog bandwidth and congest the network. Many
network switches have a built-in capability to detect when a device is jabbering and
block it until it resumes proper operation.
Alignment error:Decoded package alignment is faulty.
Symbol error: Coding symbol is missing or faulty.
CRC error: cyclic redundancy check is a type of hash function used to produce a
checksum – a small, fixed number of bits – against a block of data, such as a packet
of network traffic or a block of a computer file. The checksum is used to detect errors
after transmission or storage. A CRC is computed and appended before
transmission or storage, and verified afterwards by the recipient to confirm that no
changes occurred on transit. CRCs are popular because they are simple to
implement in binary hardware, are easy to analyze mathematically, and are
particularly good at detecting common errors caused by noise in transmission
channel.

7.4.6 SNMP Technology
SNMP is part of the Internet network management architecture. This architecture is
based on the interaction of many entities, as described in the following section.
The Internet Management Model
As specified in Internet RFCs and other documents, a network management system
comprises:
Network elements -- Sometimes called managed devices, network elements are
hardware devices such as computers, routers, and terminal servers that are
connected to networks.
Agents -- Agents are software modules that reside in network elements. They collect
and store management information such as the number of error packets received by
a network element.
Managed object -- A managed object is a characteristic of something that can be
managed. For example, a list of currently active TCP circuits in a particular host
computer is a managed object. Managed objects differ from variables, which are
particular object instances. Using our example, an object instance is a single active
TCP circuit in a particular host computer. Managed objects can be scalar (defining a
single object instance) or tabular (defining multiple, related instances).
Management information base (MIB) -- A MIB is a collection of managed objects
residing in a virtual information store. Collections of related managed objects are
defined in specific MIB modules.
Syntax notation -- A syntax notation is a language used to describe a MIB's
managed objects in a machine-independent format. Consistent use of a syntax
notation allows different types of computers to share information. Internet
management systems use a subset of the International Organization for
Standardization's (ISO's) Open System Interconnection (OSI) Abstract Syntax
Notation 1 (ASN.1) to define both the packets exchanged by the management
protocol and the objects that are to be managed.
Structure of Management Information (SMI) -- The SMI defines the rules for
describing management information. The SMI is defined using ASN.1.
Network management stations (NMSs) -- Sometimes called consoles, these devices
execute management applications that monitor and control network elements.
Physically, NMSs are usually engineering workstation-caliber computers with fast
CPUs, megapixel color displays, substantial memory, and abundant disk space. At
least one NMS must be present in each managed environment.
Parties -- Newly defined in SNMPv2, a party is a logical SNMPv2 entity that can
initiate or receive SNMPv2 communication. Each SNMPv2 party comprises a single,
unique party identity, a logical network location, a single authentication protocol, and

H-1116 Budapest, Kondorfa str. 6-8. Telefon: 06-1-481-2050
Fax.: 06-1-481-2049
a single privacy protocol. SNMPv2 messages are communicated between two
parties. An SNMPv2 entity can define multiple parties, each with different
parameters. For example, different parties can use different authentication and/or
privacy protocols.
Management protocol -- A management protocol is used to convey management
information between agents and NMSs. SNMP is the Internet community's de facto
standard management protocol.
The most basic elements of the Internet management model are graphically
represented in Figure 1.
Figure 1: The Internet Management Model
Interactions between the NMS and managed devices can be any of four different
types of commands:
Reads -- To monitor managed devices, NMSs read variables maintained by the
devices
Writes -- To control managed devices, NMSs write variables stored within the
managed devices
Traversal operations -- NMSs use these operations to determine which variables a
managed device supports and to sequentially gather information from variable tables
(such as IP routing tables) in managed devices
Traps -- Managed devices use traps to asynchronously report certain events to
NMSs

MIBs and Object Identifiers
A MIB can be depicted as an abstract tree with an unnamed root. Individual data
items make up the leaves of the tree. Object identifiers (IDs) uniquely identify or
name MIB objects in the tree. Object IDs are like telephone numbers -- they are
organized hierarchically with specific digits assigned by different organizations.
The object ID structure of an SNMP MIB defines three main branches: Consultative
Committee for International Telegraph and Telephone (CCITT), International
Organization for Standardization (ISO), and joint ISO/CCITT. Much of the current
MIB activity occurs in the portion of the ISO branch defined by object identifier
1.3.6.1 and dedicated to the Internet community.
The current Internet-standard MIB, MIB-II, is defined in RFC 1213 and contains 171
objects. These objects are grouped by protocol (including TCP, IP, User Datagram
Protocol [UDP], SNMP, and others) and other categories, including "system" and
"interfaces."
SMI Definitions
The SMI specifies that all managed objects should have a name, a syntax, and an
encoding. The name is the object ID, which was discussed in the preceding section.
The syntax defines the object's data type (for example, "integer" or "string"). A
subset of ASN.1 definitions are used for the SMI syntax. The encoding describes
how the information associated with the managed object is formatted as a series of
data items for transmission on the network. Another ISO specification, called the
