Abstract

A laser transmission system for free space optical communication is described in this paper. The distributed processing techniques are investigated to apply to all-optical transmission systems. A pair of transmission nodes is equipped with an E/O and an O/E converter and each node is controlled independently. The distributed processing system transmits the positioning data of laser beam and the control commands using TCP/IP between two PCs. A prototype of active free space optics systems is constructed and employed for experiments of tracking mobile terminals. Results confirm that the proposed techniques enable the free space optics system to pursue the unstable transmission nodes and maintain broadband communication in high quality.
