The invention provides an audio optical transmission network and a multi-network networking system, the audio optical transmission network comprises an optical part and an electrical part, broadband light generated by a light source passes through a circulator and then enters a wavelength beam splitting unit through a transmission optical fiber, the broadband light is screened into N paths of narrow-band light with equal wavelength intervals, and the N paths of narrow-band light are respectively incident into N sound detection units; n paths of interference light are generated and return to the wavelength beam splitting unit, the interference light is combined into interference wide-spectrum light, the interference wide-spectrum light enters the electrical part through the transmission optical fiber and the circulator, and the electrical part restores audio signals according to the interference wide-spectrum light and outputs the audio signals to the earphone. Optical transmission signals at the two ends are
