Abstract
An optical transmission device includes a laser configured to generate an initial optical signal, radio-frequency signal channels configured to transmit radio-frequency modulation signal, a ground channel disposed in parallel with and connected to the radio-frequency signal channels, an input optical fiber receiving the initial optical signal, a front-end optical splitting element splitting the initial optical signal, and optical transmission units. Each optical transmission unit includes a rear-end optical splitting element connected to the front-end optical splitting element, two optical splitting paths, an optical combining element, and an output optical fiber configured to output the optical modulation signal. One of the radio-frequency signal channels is disposed between the two optical splitting paths, and two of the radio-frequency signal channels are disposed at two sides of the two optical splitting paths, to modulate the optical splitting signal with the corresponding radio-frequency modulation signal.
