With the rapid development of intelligent transportation systems, the real-time acquisition, transmission, and security of massive traffic data have become key concerns. This paper proposes a unidirectional data transmission device based on optical fiber technology to reduce the security risks in data transmission between internal and external networks of transportation systems. With the unidirectional optical transmission of optical fiber, it achieves unidirectional physical isolation of data transmission channel, which maintains the security of host computers and internal networks. The network protocol stack is optimized to achieve efficient and stable data transmission. The data transfer rate from the host computer to the removable storage media reaches 100 Mb/s. This demonstrates the potential for use in the fields requiring stringent data security.
