摘　　要：随着高速光纤总线技术的逐渐成熟,具备高传输速率、高可靠性、低响应延迟、低线缆总重等特点的光纤总线开始在航天领域得到应用。在航天光纤总线的研究中,光纤通道是研究的热点。本文研究了光纤通道的交换式拓扑,并结合航天器的实际工作要求,提出了基于FPGA的光纤通道交换式拓扑的实现方案,重点设计了光纤通道的交换结构和交换器。通过Quartus II的仿真以及硬件实物实验验证了该方案的可行性。With the gradual maturation of high-speed fiber optic bus technology,fiber optical bus with high transmission rate,high reliability,low response latency and low cable weight begins to be used in the field of Aerospace.And fiber channel is a hotspot in the study of aerospace fiber optical bus.By combining with the spacecraft practical requirements,the exchange topology of fiber channel is studied and a scheme of fiber channel switched topology based on FPGA is given which focuses on the design of the fiber channel exchange structure and switch.Through the simulation of Quartus Ⅱ and hardware verification,the feasibility of the exchange structure of the proposed scheme is verified in this paper.
