Cover Story: Fast communication, especially at a large distance, is of high importance. Recently, the increased data demand and crowded radio frequency spectrum have become crucial issues. As an alternative to wire communication systems, free-space optical communication (FSO) was developed. It allows efficient voice, video, and data transmission. Due to large bandwidth, FSO can be used in various applications. The rapid development of high-speed connection technology allows reducing repair downtime and gives the ability to quickly establish a backup network in an emergency. In this paper, the communication history from mirrors and optical telegraph to modern wireless systems, in particular free-space optical communication, and outline of future development directions of optical communication are discussed.
