摘　　要：An innovative dynamically reconfigurable radio-over-fiber （RoF） network equipped with an intel- ligent medium access control （MAC） protocol is proposed to provide broadband access to train passengers in railway high-speed mobile applications. The proposed RoF network architecture is based on a reconfigurable control station and remote access unit （RAU） that is equipped with a fixed filter and tunable filter. The pro- posed hybrid frequency-division multiplexing/time division multiple access （FDM/TDMA） based MAC protocol realizes failure detection/recovery and dynamic wavelength allocation to remote access units. Simulation result shows that with the proposed MAC protocol, the control station can detect failures and recover and dynamic wavelength allocation can increase the wavelength resource utilization to maintain network performance.An innovative dynamically reconfigurable radio-over-fiber （RoF） network equipped with an intel- ligent medium access control （MAC） protocol is proposed to provide broadband access to train passengers in railway high-speed mobile applications.
