摘　　要：针对当前照射制导设备数据传输能力存在的问题,文章提出了一种基于串并收发器技术、传输速率为2.5 Gbit/s的光电通信系统设计。该设计以串并收发器为核心,采用光纤传输与现场可编程门阵列(FPGA)软件结合的方式对网络报文控制数据、状态采样数据和同步时序信号等不同速率和接口形式的数据进行组帧和解帧处理,最终实现了高速光电系统的通信。测试结果表明,该系统大幅提升了阵面数据信息的传输和处理速率,同时降低了传统阵面与地面通信系统的硬件设备数量和繁杂度,突破了阵面与地面间的传输距离限制。In view of the problems in transmission capacity of illumination guidance system,this paper presents a high speed of 2.5 Gbit/s optical system based on gigabit transceiver.The system takes gigabit transceiver as the core device.It is used to achieve a series of processing with multiple data types and multiple interface in optical fiber transmission and Field Programmable Gate Array(FPGA).It ultimately achieves the high-speed optical fiber transmission of serial data.The results show that the system can increase the processing rate of the data from guidance array to ground console.It also reduces the number of equipment in illumination guidance system,which breaks through the limit of transmission distance between guidance array and ground console.
