Abstract

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.
