We have studied a power-by-wire/fly-by-light (PBW/FBL) system for years and developed prototype equipment such as an optical data bus, electric smart actuator and flight control computer. The optical data bus includes commercial based single mode fiber, optical couplers and E/O (electro/optical) transceiver that is small enough to be installed inside each piece of electronic equipment. The electric smart actuator is a triple redundant 270 V DC EMA (electro mechanical actuator) package with embedded control electronics. Also, a new fault detection and reconfiguration capability was demonstrated using the flight control computer prototype. The functional test and environmental test for each component are almost completed. Currently, we are starting the system integration bench test in which all prototype equipment will be connected using the optical data bus. We present the prototype design, equipment test results and system integration test plan.
