DATA TRANSMISSION THROUGH FREE SPACE OPTICAL LASER
Abstract
Free space optics (FSO) is a very advanced form of communication usually named as line-of-sight communication technology that is recently providing optical transmission up to 3 Gbps of text, speech(sound), images and video graphic communications through the air as medium, allowing exchange of data without any use of conventional fiber optic cables or securing frequency spectrum licenses. FSO system could carry full duplex (bi-directional) data at giga bits per second rates over Metropolitan distances of a few city blocks, buildings or area of few kms. FSO, also known as wireless optics, which overcomes this last-mile access blockage by sending high – bit rate signals through the air using laser transmission.
