The finite gain recovery time of the reflective semiconductor optical amplifier (RSOA) causes distortion and pattern dependence at high bit rates in colorless optical network units (ONUs) of WDM passive optical network (WDN-PON). We propose and demonstrate a scheme of upstream transmission of 10 Gbps NRZ signals directly modulated via a RSOA in a 25 km single fiber, where we use a fiber Bragg grating (FBG) as an offset filter to suppress the pattern dependence and improve the RSOA modulation bandwidth. Both experimental and simulation results are provided, which are useful results for designing cost-effective colorless transceivers.
