Abstract

Free space optics (FSO) is an emerging technology that has found application in several areas of the short-and long-haul communications space. From inter-satellite links to inter-building links, it has been tried and tested. As with any technology, FSO has worked much better in some applications than in others. Free space optical systems do face a lot of problems especially from atmospheric disturbances as the signal travels in free space. Rain and snow attenuate the signal and hence decrease the range of reliable communication. Fog being composed of water droplets, can completely hinder the passage of light through a combination of absorption, scattering and reflection. Physical obstructions such as flying birds cause temporary interruption in the received signal. Nonetheless, free space optical communication systems is a viable alternative, given its optical base, bandwidth scalability, speed of deployment, re-deployment and portability, and cost-effectiveness.
