Wavelength division multiplexed-passive optical networks (WDM-PONs) are attractive solutions for future broad band access networks. However, WDM can be relatively expensive to implement owing to the cost of the specified wavelength sources. The reflective structure is a common solution to solve this problem. There is a Reflective Semiconductor Optical Amplifier (RSOA) at the Optical Network Unit (ONU) in reflective structure. Bidirectional transmission over a single fiber is applied in WDM transmission system, as it uses a single source at the Center Office side and reduces the requirement number of the fiber and cost, but also injects the Rayleigh backscatterings. A RSOA and the other reflective components in Optical Distribute Network (ODN) generate reflection. These two interferences are critical noise on the single fiber transmission system. In this paper, we have studied the influences of the reflections and Rayleigh backscattering interferences by theoretically analysis and experiment.
