We investigate the impact of the reflection in an RSOA-based WDM PON utilizing the spectrum-sliced ASE source as
the seed light. Since the spectrum-sliced ASE source has sufficiently large bandwidth to suppress the optical beat
interference (OBI) noise, we can achieve the high reflection tolerance in comparison with that in a conventional WDM
PON using the remodulation scheme. In the experiment, we systematically investigate the dependence of the reflection
tolerance on the operating conditions such as the optical power and bandwidth of the spectrum-sliced ASE source
injected into the RSOA. In the case when the injection power into the RSOA is low, the performance of the upstream
signal becomes vulnerable due to the reflection-induced incoherent crosstalk and parasitic laser oscillation. However, we
can improve the reflection tolerance significantly by increasing the optical power and the bandwidth of the spectrumsliced
ASE source. By optimizing these operating conditions, we can achieve an excellent refection tolerance greater
than -15 dB.
