We experimentally demonstrate wavelength division multiplexing passive optical network system delivering downstream 5-Gbps data and upstream 2.5-Gbps data over 153km single mode fiber on a single wavelength using pulse source that is mode-locked laser generating a single pulse of sech‘‘ shape with specified power and width, that is, soliton pulse. The optical source for downstream data and upstream data is soliton pulse generator at central office and reflective semiconductor optical amplifier at each optical network unit. We also investigate analysis of backscattered optical signal for upstream data and downstream data simultaneously. Bit error rate and Quality factor was measured to demonstrate the proposed scheme.
