Experimental network synchronization via plastic optical fiber

► Experimental network synchronization of Chua's circuits is obtained. ► Network synchronization is obtained by invoking recent results from complex systems theory. ► Synchronization among a master circuit with multiple slave circuits is achieved via plastic optical fiber. ► An application to secure network communications of analogical signal and image messages is given. ► Experimental network synchronization and communication is realized by using opto-electronics devices.
