3. Introduction
Key FSO System Components:
Laser (Tx.) and Photo-detector (Rx.).
Communication Signal [1] :
Infrared laser : 780-850 & 1520-1600nm.
Communication Medium [2] :
Free space channel: Inter-stellar,
atmosphere & underwater.
Limitations of Terrestrial LOS Technology
Shadowing by intermittent obstacles :
Trees, Multi-stored Buildings
Localised atmospheric attenuation
Fog, Rain and Clouds
