Introduction to the concepts of Free Space Optics (FSO)
FSO is a line-of-sight technology which uses LASERS and Photo detectors to provide optical connections between two points—without the fiber.
FSO can transmit data, voice or video at speeds capable of reaching 2.5 Gbps. Products capable of speeds upto 10 Gbps are expected to hit the markets within one year.
FSO units consist of an optical transceiver with a laser (transmitter) and a Photo detector (receiver) to provide full duplex (bi-directional) capability.
FSO systems use invisible infrared laser light wavelengths in the 750nm to 1550nm range.
DATA SECURITY
To overcome the security in a network two conditions are necessary:
(1) Intercept enough of the signal to reconstruct data packets and
(2) Be able to decode that information.
