Bidirectional Transmission of 10 Gbit/s Using RSOA Based WDM-PON and Optical Carrier Suppression Scheme

Abstract We have proposed and demonstrated a novel architecture of cost effective bidirectional wavelength division multiplexed passive optical network (WDM-PON) system based on reflective semiconductor optical amplifier (RSOA), using optical carrier suppression (OCS) method. RSOA is employed at the user end to remodulate the downstream lightwave for uplink transmission. The OCS scheme is used to reduce the power loss of the signal during the transmission. A data rate of 10 Gbit/s is successfully transmitted over a single mode fiber (SMF) of more than 40 km length. The outstanding transmission performances at uplink and downlink have been observed by measuring the high Q factor and the sufficient low bit error rate (BER) at the BER tester.
