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.
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.
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.
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.
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.
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.
Preferred installation Pay attention to sites Avoid (*) Concrete wall Brick wall Soft materials Chimneys Wooden constructs Metal masts or Frames Hidden heat isolations, like Styrofoam Behind window Old constructs Microwave towers (*) 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.
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 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.
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.
5 The mounting bracket In the following chapter you will find detailed description of the bracket fastenings. 5.1 Mounting brackets for the X Series GeoDesy FSO provides the mounting bracket and all the necessary components for X series units.

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.
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.
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.
Alignment of the X series The first step after the unit was placed to the bracket, and turns the units facing each other. On the back of the receiver you can find the LEDs for the local received level and the remote received level. This help will be very useful because as soon as you have received – which is very easy to achieve – you can see the effect of your local sides movement to the other side. For further information please check the Meanings of the LEDs chapter. 6.2.
6.2.2 Fine tuning 1. Site A start moving the laserhead with the horizontal fine adjustment screw by looking at the Remote end received level 2. Using the fine adjustment screws, lighten as many LEDs as possible 3. Repeat step 1-2 on Site B. 4. If necessary try step 1-2 on both sites again. 6.2.3 Meanings of the LCDs Power: The head is powered up. RX-OK: Received beam is good for communication. TP Lk: Copper link between the head and the Network equipment.

7 Management 7.1 Features The Inband network-monitoring unit is a newly developed highly featured monitoring for GeoDesy FSO manufactured laser links. This high quality equipment allows the user to monitor the link statuses such as detector voltage transmitter status, and many other features of the Laser link. Nevertheless, this chapter is intended to describe the usage of this network monitoring, and its connection and relationship with the GeoDesy FSO laserheads.
IP address: Displays the IP(Internet Protocol) address of the device which must be a unique identifier in the network. Managed head: displays the managed head type. Head Serial Number: This is the head serial number and during the Activation process we will ask for this number.
RX OK: this information is showing that the receiver is enabled. It basically means that there is valid signal with necessary strenght is received in the local end. Device setup The device setup screen leads you to the main monitoring options. Here the alarms can be set and main information about the Laser head. Device name: uniqe identifier of the device Managed head: Type of the laserhead Detector alert level: when the received level reach this value, the alarm will be triggered.
IP Setup Clicking on the IP Setup link you can have access to the Ethernet module of the system, this will make easy access to the IP number and/or port settings. These settings are sensitive setting and some of them cannot be restored by the user. Please always do the changes with extra care! If you have doubt in any step, do not hesitate to contact the technical support of the manufacturer website for further information. Local IP: the IP address of the local device can be set in this box.
SNMP Setup One of the main features of the device is the SNMP(Simple Network Monitoring Protocol). The SNMP settings can be set on this page. Trap address: The IP address of the SNMP trap over the network. Trap events in the system you have possibility to setup three different trap event. For further details on the trap event see Trap event list chapter of this book. In this section there are the settings of the SNMP Agent.
Security On the security section you can set the username and the password for the unit. If you have forget the usernam and/or the password please contact The technical support. 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.
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.
Auto-focus setup (AF) Automatic divergence corrections: • Enabled (auto): adjust beam size to the best level according to the remote level. • Disabled (manual): It disables the automatic adjustment routine, and lets the user adjust the beam size by using the „STEP” buttons. Last activity: which the AF (auto focus) has done. • idle: AF was not active.. • setting default: saves the standard settings. • moving default: return to default settings. • moving to open: opens to widest beam.
Mandatory Management Activation Thank you for buying our product. Please read this note carefully. From software version (3.2.1218/R090x)!

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.
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.
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.
an interface is an example of a counter. In SNMPv1, counter size was not specified. In SNMPv2, 32-bit and 64-bit counters are defined. Gauges -- Non-negative integers that can increase or decrease, but latch at a maximum value. The length of an output packet queue (in packets) is an example of a gauge. Time ticks -- Hundredths of a second since an event. The time since an interface entered its current state is an example of a tick. Opaque -- Represents an arbitrary encoding.
from an agent, it initiates a Get operation, followed by a series of GetNext operations. GetBulk -- New for SNMPv2. The GetBulk operation was added to make it easier to acquire large amounts of related information without initiating repeated get-next operations. GetBulk was designed to virtually eliminate the need for GetNext operations. Set -- Allows the NMS to set values for object instances within an agent. Trap -- Used by the agent to asynchronously Inform the NMS of some event.
PDU type -- Specifies the type of PDU being transmitted. Request-ID -- Associates requests with responses. Error-status -- Indicates an error and an error type. In SNMPv2 GetBulk operations, this field becomes a NonRepeaters field. For these operations, this field defines the number of request-ed variables listed that should be retrieved no more than once from the beginning of the request. The field is used when some of the variables are scalar objects with only one variable.
The Digest Authentication Protocol verifies that the message received is the same one that was sent. Data integrity is protected using a 128-bit message digest calculated according to the Message Digest 5 (MD5) algorithm. The digest is calculated at the sender and enclosed with the SNMPv2 message. The receiver verifies the digest. A secret value, known only to the sender and the receiver, is prefixed to the message.
Trap event list Alert disabled: there is no alert coming up for this trap Temperature: The agent will send an alarm if the value goes above the preset value. For further details please see Temperature alert level in the Device Setup chapter. Detector: The agent will send an alarm if the value goes above the preset value. For further details please see Detector alert level in the Device Setup chapter. Transmitter: if the transmitter fails operating the agent will send an alarm.
