In order to meet the demands of high-speed data transmission in embedded systems,a fiber optic com-munication system solution is proposed based on RapidIO protocol. The conversion of the optical to electrical signals is executed by optical modules. The high-speed transceiver is employed to realize the physical layer pro-tocol and Field-Programmable Gate Array(FPGA)is adopted to acheive the logic layer protocol. The test results demonstrate that the program is cost-effective and reliable. With the data throughput of 1.25 Gb/s,the pro-posed scheme has been successfully applied in an electronic toll collection(ETC)system.
