Briefly introduced the principle of optic fiber / wireless transmission way. The transmission characteristics of optical fiber / wireless transmission technology in railway communication are analyzed. Optical fiber / wireless transmission method suitable for the characteristics of railway dispatching communication, terminal stations can be set according to the field strength distribution along the line. Wireless users in the dispatching area do not need to conduct network frequency switching, continuous communication. The experimental system made a brief analysis and calculation.
