Integrated All-Optical OFDM - WDM Transmission of 4x2.5Gbps Data Over 50km for a Radio Over Fiber Network
Transmission of data above gigabytes, paved way to all-optical transmission, especially all-optical OFDM which enables wide band data to be transmitted over narrow band parallel channels. All optical technology always has higher data rate than electronic system. OFDM is generated by electronic Fast Fourier Transform (FFT) or Hartley Transform. But achieving OFDM by electronic processors is quite challenging for data rate of 100Gbps or above. The proposed system integrates all-optical OFDM with Wavelength Division Multiplexing (WDM), and the performance is evaluated for 4X2.5Gbps RoF network.
