| 摘 要： | 为实现模拟和数字信号的光纤多路传输,采用复杂可编程逻辑器件（Complex Programmable Logic Device,CPLD）和时分复用技术,设计了光纤多路传输系统.利用EPM7128对传输的数字信号按照设计的帧格式进行时分复用发送,接收端将接收的光信号经光电转换之后解复用,恢复出传输的各路信号.实验测试表明：系统可稳定的实现四路模拟信号和八路数字信号的时分复用光纤传输.

| Abstract: | Complex programmable logic device（CPLD） and the technology of TDM were adopted to achieve the purpose of optical fiber multiplex transmission of analog signal and digital signal.According to the required frame format,the transmitting digital signals were TDM by EPM7128.At the receiver,the receiving optical signals were recovered through the photoelectric conversion module and the de-multiplexing module.It was shown,through experimental tests,that the system realized stable optical fiber time-division multiplex transmission of four-channel analog signals and eight-channel digital signals. |
