摘　　要：根据光纤线导数据传输的特点,提出了一种基于现场可编程门阵列(FPGA)实现鱼雷光纤线导总线数据传输的方法,采用自定义的成帧格式与8B/10B编解码相结合的方式,可以简化系统结构,仅用单片FPGA就可实现,具有组成简单、传输延迟低、传输可靠性高等优点。仿真结果表明,在光纤数据的有效传输速率达到100 Mb/s条件下,误码率小于10^(-6),该方法可实现光纤线导以太网总线数据的可靠传输。According to the characteristics of optical fiber data transmission, this paper proposes a data transmission method through the optical fiber bus of a wire-guided torpedo based on field-programmable gate array（FPGA）.The method combines the custom framing format with the 8B/10B coding and decoding, and can be achieved only by a single FPGA. It simplifies the system structure, and has the advantages such as simple composition, small transmission delay and high transmission reliability. Simulation result shows that the bit error rate is less than 10^-6 as the effective optical fiber transmission rate is 100 Mb/s. This method can realize reliable data transmission through Ethernet bus for optical fiber wire-guided communication.
