Abstract
In a central light seeded PON, it is shown that the resilience to the Rayleigh backscattering can be strongly different for NRZ or RZ-direct modulated R-SOAs at the OLT. It is experimentally demonstrated that the RZ modulated signal has an increased tolerance to the in-band crosstalk compared to NRZ format, thanks to the spurious chirp. Error-free uplink communications down to 10 dB signal-to-crosstalk level are obtained.
