C- and O-band operation of RSOA WDM PON self-seeded transmitters up to 10 Gb/s [Invited]

We propose a network-embedded colorless self-tuning transmitter for wavelength division multiplexed (WDM) networks based on self-seeding in reflective semiconductor optical amplifiers (RSOAs). We compare up to a 10-Gb/s data rate in either O-band or C-band operation. In particular, the transmitter exploits a two-Faraday rotator configuration to ensure polarization-insensitive operation and allowing for the exploitation of high-gain C- and O-band RSOAs, which present a very high polarization- dependent gain. Two different multiplexers and various lengths of drop fibers constituted the networkembedded transmitters in order to evaluate various dispersion load influence on cavity buildup. Moreover, transmission over standard single-mode feeder fiber has been evaluated both at 2.5 and 10 Gb/s to compare the performance in both bands, confirming the absence of chromatic dispersion penalties for the O-band operation.
