In this paper, an approach of a colorless ONU comprised by a Fabry-Pérot filter and a Semiconductor Optical Amplifier for all-optical clock recovery of the downstream signal, followed by a Mach-Zehnder modulator as the upstream modulator is experimentally demonstrated. The all-optical clock recovery performs data erasure allowing for efficient wavelength reuse of the downstream signal for upstream remodulation. Operation at a fullduplex 10Gb/s symmetrical data rate and 20 dB loss budget is
