Focused on the issue of importing external data to secret-associated network and avoiding the risk of revealing the confidential data, A Multi-interface Safe High-speed Optical Fiber One-way- Transmission System was proposed,which allows data transmission without compromising the confidentiality of the information on the higher security classified network. This paper explains the detail implementation about hardware and software of unidirectional data transmission. Computer high-speed transmission interface and optical fiber communication technology was used to improve high-speed data transmission reliability. Forward error correction code was used in physical layer for controlling transmission errors and improving the reliability of the system. A high reliable connectionless transfer layer agreement was designed to realize one-way and reliable transmission of data. Plug and play multi-interface technology was used to improve the ease for use. The system designed provides a whole set of one-way transmission solution that transmit data from non-confidence network to confidence network. The theoretical analysis and simulation results show that the high-speed one-way transmission can be achieved by using the unidirectional data import system, and better performance in transmission efficiency and accuracy.
