Abstract A full duplex WDM-PON system is designed and demonstrated based on carrier reusing scheme and by employing differential quadrature phase shift keying (DQPSK) modulation in downlink and inverse return-to-zero modulation in the uplink to transmit 40 Gbps and 20Gbps data-rate respectively. Three Mach-Zehnder modulators are used sequentially to realize the 67 % carrier suppressed return to zero (CS-RZ) DQPSK modulation in the downlink transmission. Very low bit error rate values @10‒9 and clear eye-diagrams are observed over a 40 km single-mode-fiber transmission in our proposed full-duplex configuration.

AbstractWe have proposed and demonstrated a full-duplex wavelength division multiplexed passive optical network (WDM-PON) configuration based on reflective semiconductor optical amplifier (RSOA). RSOA is used for reusing and remodulate the downlink signal in the uplink. We have used external modulation scheme for transmitting 20 Gbps data rates in two channels over a 40 km single mode fiber (SMF). The uplink and the downlink performances are checked by the bit error rate (BER) and the eye diagrams.
