Abstract

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