We have demonstrated a novel scheme of reflective semiconductor optical amplifier (RSOA) based bidirectional gigabit WDM-PON using suppressed optical carrier (SOC) and polarization beam splitter (PBS). While LiNbO3 Mach-Zehnder modulator (LN-MZM) located at the central office (CO) generate 4 GHz SOC as the seed light for uplink transmission, RSOA at CO modulate the downlink data. At optical network...
WDM-PON is viewed as a suitable next generation access network technology due to its capability of delivering high bandwidth and OPEX saving features. In this paper, several research activities of DWDM-PON are introduced and analyzed. Technical issues and propects are also presented.
An evolution scenario of broadband access is proposed, using a wavelength-division-multiplexed passive optical network (WDM-PON) and a hybrid WDM/time-division-multiplexed PON (WDM/TDM-PON). As candidate technologies to be applied in the evolution, the laser-injected reflective semiconductor optical amplifier-based WDM-PON and hybrid WDM/TDM-PON with a remotely pumped erbium-doped fiber amplifier...
It is addressed from the network provider's aspect that WDM-PON is suitable for the next generation optical network. Several schemes of R-SOA based WDM-PON are introduced and analyzed in terms transmission performances. The possibilities for further improvement of the performance are suggested.
