Free Space
Optics is a proven technology.
A well
installed Laser Link will give you years of trouble free bandwidth
as long as service is regular and the unit is well placed in the
first installation.

Laser Technology
The Benefits:
There are many reasons why customers choose FSO wireless solutions
Licence-free operation
No need to obtain frequency licences for the operators of laser based
wireless cabling solutions. Connections can be established as a
ONE-TIME investment with no recurring costs.
Cost-effective:
Reduce your installation and lease line costs. This is a wireless
installation - all lease line costs are eliminated giving you an
incredibly quick return on your investment. Installation costs are
minimized as there is no need for the costly installation of cables.
Time is saved as there is no need to seek permissions for digging
roads or obtaining special licenses.
Investment protection:
By using future proof fibre optic interfaces, the solution protects
customer investments. The modular design of mean that most equipment
can be easily and cost-effectively upgraded for greater bandwidth or
distance.
No interference:
Because they use infrared light for communication, the performance of
Wireless Cabling systems is not effected by electro-magnetic noises
and is not subject to interference with traditional wireless devices.
High bandwidth:
Optical free space data transmission gives you the same bandwidth and
speed of fixed optical fibre.
Secure data transmission:
Free space transmission is one of the safest transmission methods of
its type because:
- Direct interception is virtually impossible with the concentrated
beam and physical placement of the equipment-well above ground level.
- No instruments such as spectrum analyzers can detect the
communication.
Quick installation:
A Wireless Cabling solution is quick and easy to deploy. All solutions
are plug and play.
Excellent price/performance:
Wireless Cabling systems have outstanding low cost per bit ratios.
Flexibility:
The Wireless Cabling systems are divided into distance ranges-
customers select the system that matches their needs. They can be
deployed in a wide variety of network architecture and mesh systems.
They can be installed roof to roof, window to window, window to roof
or wall to wall.
How
our Lasers Work:
Laser
- A device that produces coherent light with a narrow range of
wavelengths. Free space optics operates in the infrared spectral range
common with the fiber optic communications and is based on
semiconductor laser technology due to small size, power and cost. Most
of these lasers are also common within the fiber optic industry making
availability not a problem. In digital transmission the transmitter is
modulated by the signal that carries the network traffic similar to
fiber-optics, during this process electrical data is converted into
optical, this conversion keeps the transmission route independent of
the protocol and operates as a physical layer one link (non-protocol
tansparent link).
The
receiver picks up the modulated light and then converts the optical
bit stream back into an electrical signal making the connection
complete. A digital signal is a series of 0' and 1s, modulation for
FSO is achieved simply by turning the light source on and off in
response to the electrical signal either by self modulation or use of
a shutter. The torch comparison is a good explanation - you can
communicate with someone far away at night simply by switching a torch
beam on and off in a predetermined sequence, the Laser is our modern
version of the torch (on and off) working at 300,000km/s this is
optical communications at the speed of light. FSO systems are simple
binary "1" is light on "0" is light off the receiver is designed to
recognise these two different states compensating for "background
noise" such as ambient light completing the communication process.
