High-speed fiber-linked remote reconfiguration

Recently, fiber networks and undersea fiber optic cables have become widely used throughout the world. Because of its much lower attenuation and interference, optical fiber is superior to copper wires for long-distance applications. Such fibers´ transfer rates and distances reach GHz-order and over 100 km. Up to now, a remote configurable FPGA system using current fiber networks was reported. However, since its configuration speed was very low, dynamic highspeed reconfiguration was impossible. This paper therefore presents a high-speed remote reconfiguration experiment using a bundle of fiber networks and an optically reconfigurable gate array. Such architecture presents the possibility of a remote high-speed dynamic reconfigurable hardware system.
