For years, Pepperl+Fuchs with the brand Visolux has been one of the leading manufacturers of optical data communication systems and has offered a complete, state-of-the-art product portfolio with numerous options used around the world.

Optical data transmission systems allow bi-directional communication for storage and retrieval systems, transfer cars, automated guided vehicles, and monorail conveyors. They replace complex and problematic cables, slip rings, and other transmission methods. The transfer between two stations takes place with infrared light, which is modulated by a data clock. Optical data couplers with many common interfaces used in industry are available. The data transfer takes place either serially or in 8-bit parallel mode.
