| 摘 要： | 当光纤信道中的光损耗幅度出现较大且快速变化时，在接收端为了能快速地跟踪光信号强度变化、输出稳定信号，文中利用交流耦合接收技术，同时根据光纤传输信道要求，采用8B／10B信道编码技术。使用光损耗快速变化的光纤传输信道对接收组件进行了视频传输实验，在信道光损耗连续变化情况下，视频监视器的输出图像显示正常，无抖动，具有响应速度快和信号输出稳定的特点，满足系统设计要求。

| Abstract: | When the large and rapid change of the amplitude of the optical loss in the fiber channel, in order to quickly track changes of optical signal strength and the signal output stabilization at the receiving side, AC-coupled receiver technology was used in the paper, at the same time according to the optical fiber transmission channel requirements, 8B/10B channel coding techniques was adopt. Video transmission experiment uses the optical fiber transmission channel of the optical loss rapid for reception component, under channel optical loss changes continuously, the output image of the video monitor display normal, without shake, with the characteristics of fast response and stable signal output it is consistent with the requirements for the system design. |
