Abstract

Optical-carrier-distribution using reflective-semiconductor-optical- amplifier (RSOA)-based colorless optical-networking-unit (ONU) is a promising candidate for the wavelength-division-multiplexed passive-optical-network (WDM-PON). However, commercial available RSOA has a typical modulation-bandwidth of ∼1GHz, which is not enough for the future bandwidth demand. Here we demonstrate a WDM-PON using 1GHz bandwidth RSOA-based ONU, which can be operated up to 13Gbit/s. Experimental results show that 20km singlemode-fibre transmission of the 13Gbit/s orthogonal-frequency-division-multiplexed (OFDM) signal can be achieved with bit-error rate lower than the forward error correction threshold.
