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. © 2012 Wiley Periodicals, Inc.
