An optical frequency comb source is used to provide the multi-wavelength seeding light, while reflective semiconductor optical amplifiers (RSOAs) are installed in both optical line terminal (OLT) and optical network units (ONUs) as colorless transmitter. The experimental results show that the bi-directional transmission for 1.2 Gbit/s data rate is achieved over 80 km single mode fiber (SMF).
