10Gbps bidirectional transmission GPON network based on single fiber

摘要

We proposed and demonstrated a bidirectional GPON architecture supporting 10Gbps data transmission through single fiber cable network. Data is transmitted utilizing a Non Return to Zero Differential Phase Shift Keying (NRZ-DPSK) and re-modulate the downstream signal using intensity modulator (on-off keying OOK) in Return to Zero (RZ) format to transmit upstream data, supporting data rate of 10Gbps/channel is an optimized network in full duplex mode. Simulation results confirmed that successful transmission using 50GHz channel spacing is achieved over a distance of 25km.
