摘　　要：为促进光纤通信向大容量、远距离和高速率方向发展,设计了一种基于嵌入式技术的光纤通信链路自动控制系统。利用光纤发射/接收器获取光纤信号,使用主电子控制模块对输入信号进行集中编码,利用信号转换电路处理编码结果,将转换结果传送到光纤通信存储模块。通信单元以串行方式将两个单元的控制信号传送到链路,其输出端选用光电隔离器输出接收到的控制信号,实现光纤通信链路自动控制。实验结果表明:该系统控制后的各链路处理和排队时延均降低50%左右;各链路的每秒发送记录数始终在720~840条范围内变化,且总带宽利用率均在90%以上。In order to promote the development of optical fiber communication towards large capacity, long-distance and high-speed, an automatic control system of optical fiber communication link based on embedded technology is designed in this paper. The optical fiber transmitter/receiver is used to obtain the optical fiber signal, the main electronic control module is used to centrally encode the input signal, the signal conversion circuit is used to process the coding result, and the conversion result is transmitted to the optical fiber communication storage module. The communication unit transmits the control signals of the two units to the link in serial mode, and its output end selects the photoelectric isolator to output the received control signal to realize the automatic control of the optical fiber communication link. The experimental results show that the processing and queuing delay of each link are reduced by about 50%;The number of records sent per second of each link always varies from 720 to 840, and the total bandwidth utilization is more than 90%.
