Free Space Optics (FSO)??
FSO is a line of sight technology that uses devices such as lasers to establish connectivity for video and voice communication
Currently, It can allow upto 2.5 Gbps of data rate but can be increased to 10 Gbps using WDM
FSO is based on connectivity between two stations consisting of optical transceiver to achieve full duplex communication
Technology: How it works?
FSO is a pretty old and relatively simple technology which has been used for more than 30 years. FSO enables similar bandwidth transmission abilities as fiber optics, using similar optical transmitters and receivers
It involves two FSO units (similar to BTS of wireless technology) each consisting of high power laser transmitters and receivers, a telescope is used in conjunction to guide the light and capture it at the receiving end. It is then typically interface with network switches, hub, bridge or router via multimode fiber
