2Introduction
2.1 What is FSO?
FSOis freespaceopticsp rovides 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
communicationsolution.AncientChinesedevelopedaprotectionsystemagainstthe
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
reflectthesuntotheremotetowers.Inthiswaytheareacouldbepreparedagainst
the attack in a very short period of time.
Inthe ancienttimesforthis communicationusethemirror
asatransmitterand 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.
CurrentFSOsystemsusealaser-diodeasalightsource,
and a receptor diode (photo diode) to receive the signals
comingfromthelaser diode from the transmitter side. But
thebasicelementsare still the same: line of sitebetween
thecommunication nodes, and individualline coding. Itis allabout performance.
Black Box offersFSO 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
needmoreandmorepowertobeseenfromtheremote
side.Achievablepowerlevelsarelimitedbyanumberof
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
sensitivetosensedelightemittedfromtheremoteside.
BlackBoxoffershightransmitpowerandalsoveryhard
receiver sensitivity. These two factors combined to provide one of the best
performing FSO systems on the market today.

This manual describes theBlackBoxLWUproductoffreespacelasertransmission
system.
The Black Box LWU product offers cost effective reliable free space laser
transmission for100Mbpsdatatotheair,whereacleanline of site is available. It
deliversthemosteffectivepoint-to-pointconnectionbetween computernetworksor
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.
Suitableforfactoriesorindustrialenvironmentswherehighnoiselevelcaninterfere
withthetransmitteddata. The best choice tomakeaconnectionacrossriversand
othern atural or artificial obstacles, where cable is not available.
The transmission technique used in the Black Box FSO devices provides
transparent and wire-speed data transfer with virtually zero latency. Because they
use infrared light as the transmission medium, Black Box LWU system do not
requirefrequency licensesandthetransmission isnoteffectedbyelectro-magnetic
orradio-frequency interference. Basically theBlack BoxLWUlink canbeconsidered
as a virtual fibre in the air, which ends in real fibreoptic 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.
Theshieldprotects the device from direct sunlightandprovidesextraairisolation.
The Black Box LWUsystems comprise two laser-heads and the two indoor
interconnectionunits(OIU)-one at each end. The interface connections are housed
in the outdoor unit together with the PSU of the system.

2.2 Optical Free-spaceTransmission
Theprincipleusedinfreespacelasertransmissionisverysimilartotheoneisused
forfibreoptictransmission.Thedifferenceiswhilefibreopticdevicesuseelectronics
andopticsoptimizedfortransmissiontotheair.Alsoonecanobservetothesimilarity
inthetransmission properties. Nogalvaniccontact,noground-loops, no needfor
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).
Thelaser-headsareusuallyplacedontopofbuilding,wherethecleanlineofsiteis
guaranteed and the beam cannot be interrupted.
In the head the incoming signal is amplified, encoded, and then drives the laser-
diode.Thetransmitteropticsassurestheproperbeamshapeandcontrolsthebeam
divergence. The receive optics perceives and directs the transmitter signal to the
photodiode.Thediode converts it back intoelectrical,thanitisdecoded,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-transmittingpower,transmitter’swavelength,beamdivergence,
receiver optics diameter, receiver sensitivity, parameters of optical system and
casing.Theseparametersdeterminethesystem’scharacteristicatacertaindistance
and are controlled by system design and factory set up.
Weather conditions-molecularabsorption,particle scattering andturbulence.These
elementshavegreateffecton the operational conditions of the system. Wedonot
have very much influence on them; proper product selection can eliminate the
undesirable effects.
Environmental conditions-buildingmovements,directsunlight,refractivesurfaces.

2.3 Typicalapplications
Most typically the Black Box LWU is used to interconnect LAN-s. The system is
protocoltransparent, thusotherapplications alsocanbetakenintoconsideration.
Appropriateinterfaceconvertersareneededandsystembandwidthmustbe matched
for that.
Here we collected some circumstances, where the employment of theBlackBox
LWU is the most adequate and cost effective solution.
Thoseare:
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
limitedspeed,andhighrentalcost.WithLaserbit
links you can establish on line LAN-to-LAN
connections.
Industrial areas
Where you have noisy environment with high EMI or
RFI.Factorybuildings,airportobjectscanbeconnected
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.
