What is FSO?
What is a Free Space Optical System?
A Free Space Optical system is similar to a point-to-point, infrared, wireless laser transmission
designed for the interconnection of two points which have a direct line of sight. The system has the same principal as a wireless bridge however, uses light to transmit data rather than a wireless signal.
The systems operate by taking a standard data or telecommunications signal, converting
it into a digital format and transmitting it through free space. The carrier used
for the transmission of this signal is Infra red light and is generated by either
high power LED or low power laser diode(s).
The basic principles for the transmission of a signal along a fibre are the same
as for transmission through free space.
The easiest way to visualise the communications service FSO is to imagine two points
interconnected with optical fibre except rather then fibre the connectivity is provided
by FSO.
