The paper explorers Free Space Optical (FSO) communication with its flashes and corns. FSO technology is useful where the physical connection is impractical due to high cost or other considerations, and in most cases, optical data transmission is done via optical fibers, because it allows transmission over relatively large distances without alignment issues and relatively very less disturbing influences of atmosphere. But optical data transmission using fiber has also many limitations. Some limitations are removed by FSO technology, such as it provides high data rates, low power consumption, low installation cost and easily upgradable. FSO performance parameters, i.e., internal and external parameters, and some modulation techniques used in FSO technology are also discussed.
