摘　　要：　在信息传输的各个领域中,光纤作为传输信号媒介的应用得以迅速发展。光纤的音频多路数字化传输也是光纤领域目前开发的热点课题之一,它充分利用光纤本身所具有的各种特点,使音频信号的传输更有效、更可靠。本文利用串行信号的时分复用技术,完成了多路音频数字化信号的光纤传输。提出信号传输中,数据信号和控制信号的复用及解复用解决方法。In many fields of information transmission, the fiberoptic as a transmission media has been playing a proper role. The digitized transmission of multichannel audio has become one area of active research, by utilizing the specific property of fiberoptic to make the audio transmission more efficient and more reliable. The method of fiberoptic transmission of multichannel digitized audio signal, which uses the timedivision multiplexing(TDM) of series signals is intraduced. The solving process to the multiplexing and demultiplexing of digital signals and control signals in the signal transmission is proposed.
