A new architecture for a wavelength‐reused wavelength division multiplexed‐passive optical network, which is simultaneously transmitting both a wireline data and a wireless one, is proposed and demonstrated experimentally. The proposed scheme uses a Mach–Zehnder modulator in the central office and a reflective semiconductor optical amplifier in the optical network unit. The subcarrier multiplexing method is utilized to simultaneously generate a wireline data and a wireless one for a downlink transmission. A downlink light is reused to transmit an uplink data using a reflective semiconductor optical amplifier. A transmitted downlink data is suppressed due to the gain saturation effect of a reflective semiconductor optical amplifier in the optical network unit and it is possible to directly remodulate an uplink 1.25‐Gb/s baseband data. A 1.25‐Gb/s bidirectional error free transmission is accomplished after 20‐km optical transmission. © 2009 Wiley Periodicals, Inc.
