1Introduction
This manual describes the LaserBitLB Pinto series of free space laser
transmission system including the following models:
E100 E100TP
E1 E2
E10 E3
E10TP
The LaserBit-Pinto product range offers cost effective, reliable free space laser
transmission for 2Mbps up to 155Mbps data through the air,where a clear line
of sight is available.It delivers the most effective point-to-point connection
between computer networks, or telephone exchanges.
No need for installing cables, no rental cost, no licensing requirement.
Ideal for urban areas or city centres, where the use of leased lines is expensive.
Suitable for factories or industrial environments where high noise levels can
interfere with transmitted data. The best choice to make a connection across
river and other natural or artificial obstacles,where cable is not available.
The transmission technique used in the LaserBit FSO devices provides
transparent and wire speed data transfer with virtually zero latency. Because
they use infrared light as transmission medium, LaserBitsystems do not require
frequency licenses and the transmission is not affected by electro-magnetic or
radio-frequency interference. Basically, the LaserBitlink can be considered as a
virtual fiber in the air, which ends in real fiber optic cable at both ends.
Our product is built using high quality electronic components for operation in
even the most adverse conditions.
Metal housing gives a robust, waterproof environment for the electronics.
The shield protects the device from direct sunlight and provides extra air
isolation.
The LaserBit Pinto system comprises of two Pinto Type Laser Heads and two
Outdoor Interconnection Units (OIU) –one at each end. The interface
connections are housed in the OIU together with the PSU of the system.

LB Pinto 400 V329/8
Best practices were employed in cost engineering throughout the development
of LaserBit
Invisible laser radiation, Class 3B laser product. Looking directly into the
laser beam can cause permanent damage to the eye!
1.1 Optical free space transmission
The principle used in free space laser transmission is very similar to the one is
used for fiber optic transmission. The difference is while fiber optic devices use
electronics and optics optimized for optical fiber, free space communication
equipment deploys electronics and optics optimized for transmission through the
air. Also one can observe 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 fiber or copper, but has to cope with the dynamically
changing parameters. For instance while the attenuation of an optical fiber is
constant, the attenuation of the atmosphere between the laser units can change
dramatically (depending on the weather conditions).
The LaserBitheads are usually placed on top of buildings, where the clear line
of sight is guaranteed and the beam cannot be interrupted.
In the head the incoming signal is amplified, encoded, then drives the laser
diode. The transmitter optics assures the proper beam shape and controls the
beam divergence. The receiver optics perceives and directs the transmitted
signal to the photodiode. The diode converts it back into electrical, then 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.

LB Pinto 400 V329/9
?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.
1.2 Typical applications
Most typically the LaserBit-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 LaserBit
is the most adequate and cost effective solution. Those are:
1.2.1 Areas with natural or artificial obstacles
Where cable is actually not an alternative, like across rivers or railways or
in rugged terrain.
1.2.2 Urban areas
Where only leased lines are available with limited speed and high rental
cost. With LaserBitlinks you can establish on line LAN-to-LAN
connections.
1.2.3 Industrial areas
Where you have noisy environment with high EMI or RFI. Factory
buildings, airport objects can be connected through laser link.

LB Pinto 400 V329/10
1.2.4 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.

3.1 Preisntallation
3.1.1 Site Survey
3.1.1.1 Key factors of operation
There are four key issues that the site survey has to shed light on. The proper
system operation cannot be guaranteed without satisfying all the four
requirements.
?Clear line of sight -first of 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 the 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.

?Exact distance measurement -because the unit was designed for 400
meter operation the higher distance will decrease the availability
dramatically. If the distance is too small contact your distributor or
LaserBit support for information of the special installation!
?East-West orientation -although the receiver optics is equipped with
optical filters to protect the receiver diode from the effect of undesired
light sources, the direct sunshine can cause saturation of the diode. This
prevents the system from working properly for several minutes a day in a
certain time of the year. In most of 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.
3.1.1.2 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 the changing of humidity. Give preference to concrete or brick
buildings. On the other hand high structures like towers, skyscrapers or poles
always subject to great movement. Mount the support frame to basic holders of
the building or near corners, as they are the most stable spots. Use appropriate
consoles for wall mounting. If 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 changing. Big chimneys and smokestacks may look
stable, but as their inner temperature varies they can also move. Vibration
caused by heavy traffic, trains, 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.
