FULL COLORLESS GIGABIT WAVELENGTH-DIVISION MULTIPLEXED-PASSIVE OPTICAL NETWORK SUPPORTING SIMULTANEOUS TWO DIFFERENT DATA TRANSMISSION

A novel wavelength-division multiplexed-passive optical network scheme supporting the transmission of heterogeneous data and broadcast signal is proposed in this article. Both optical carrier suppression and multiplexing of arrayed waveguide grating with 50-GHz channel spacing are used to generate each optical carrier for the transmission of these data. A reflective semiconductor optical amplifier is also used, so that this architecture operates irrespective of wavelength. In case of downlink transmission, error-free transmissions (bit error rate of 10-11) of 1.25- and 2.5-Gb/s baseband data are achieved at the same time. Also, 64-quadrature amplitude modulation signal of 60 Mb/s is transmitted showing the error vector magnitude of 4.7% in the presence of the transmission of 2.5-Gb/s baseband data.
