Abstract: Focused on the issue of importing data to secret-associated network, and avoid the risk of revealing the confidential data, A Multi-interface Safe High-speed Optical Fiber One-way Transmission System was proposed. This paper explains the detail implementation about hardware and software of unidirectional 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. High reliable connectionless transfer layer was designed to improve the reliability of the system. Plug and play multi-interface technology was use to improve the ease for use. The theoretical analysis and simulation results show that the high-speed transmission can be provided by using the unidirectional data import system, and better performance in transmission efficiency and accuracy.
