Abstract
Today's information economy depends on the
transmission of data, voice and multimedia across
telecommunication networks. optical networks remain the most ideal medium for high-bandwidth communications for true connectivity. There are two distinct types of optical communications: Fiber optics (fiber-optic cable) and optical wireless systems based on free-space optics (FSO) technology.
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. Free-space optics (FSO) refers to the transmission of modulated visible or infrared beams through the atmosphere to obtain broadband communications. Most frequently, laser beams are used, although non-lasing sources such as light-emitting diodes or IR-emitting diodes will serve the purpose. The difference in fiber communication and FSO is that the energy beam is collimated and sent through clear air or space from the source to the destination, rather than guided through an optical fiber. much used in the enterprise, mobile communication.
