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 wire for long-distance applications. Optical fiber data transfer rates and distances reach GHz-order and over 100 km. Previously, a remote configurable field programmable gate array (FPGA) system using current fiber networks was reported. However, since its configuration speed was very low, dynamic high-speed reconfiguration was impossible. Therefore, this paper presents a 4-configuration context fiber-linked optically reconfigurable gate array using a bundle of fiber networks and an optically reconfigurable gate array.
