INTRODUCTION
AN OPTICAL COMMUNICATION SYSTEM WITHOUT FIBERS or in other words ‘’WIRE FREE OPTICS’’.
FSO is a line-of-sight technology that uses invisible beams of light to provide optical bandwidth connections that can send and receive voice, video, and data information.
Infrared ( IR) beams , laser beams, light-emitting diodes, IR-emitting diodes (IREDs) is used as optical source for transmission.
HISTORY
In the 1880, Alexander Bell expanded his "photo-phone" communication which modulated by sunlight.
BIRTH OF LASER FSO COMMUNICATIONS
In the mid-1960's NASA initiated experiments to utilize the laser as a means of communication between the ground and space.
