Abstract

We proposed a new method for suppressing the OBI noise in RSOA based WDM/SCM-PON. This method uses the injection-locked FP-LD in central office, which acts as high pass filter into modulation bandwidth of master laser. As an experimental verification, we could find that CNR has increased up to 12 dB and EVM after 10 Km transmission was reduced from 10% to 5% comparing with those without an injection-locked FP-LD for the received optical power of -10 dBm
