摘　　要：随着计算机和通信技术的不断发展,光纤传输以其容量大、衰减小、抗干扰性能好等优点,成为数据传送的重要方式之一。提出了一种基于以太网控制器DM9000A和光电转换器AFBR-5803的光纤传输系统设计方案。该方案完成了DM9000A与AFBR-5803之间的硬件接口电路设计,在此基础上实现了Linux系统下DM9000A驱动程序的开发,并对程序中数据发送、接收等关键事件进行详细阐述。测试结果表明该设计能够准确、快速地完成数据的发送和接收。该光纤传输系统具有外围器件少、硬件接口简单、开发周期短等优点。Fiber optic transmission with its large capacity, little attenuation and anti-interference has become an important way of data transmission with the development of computer and communication technology. A solution for fiber optic transmission system based on Ethernet controller DM9000A and photoelectric converter AFBR-5803 is presented in this paper. The hardware interface circuit between DM9000A and AFBR-5803 is designed and on this basis, the driver development of DM9000A in Linux environment is achieved. The key events such as data sending and receiving of the driver are elaborated. Data transmission can be completed accurately and quickly by the design. The design makes the fiber optic transmission system with few peripheral devices, simple hardware interface, short development cycle and so on.
