We present a novel optical network unit (ONU) featuring a "colorless" directly modulated laser (DML) enabled by a hybridly integrated all-optical wavelength converter (AOWC), supporting operation beyond 10 Gb/s. It incorporates a semiconductor optical amplifier (SOA) for wavelength conversion and two cascaded delay interferometers (DIs) for spectral processing. The ONU was proven at full duplex 10-Gb/s data rate in a WDM passive optical network. Index Terms-Fiber-to-the-home (FTTH), optical
