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.
