We propose and demonstrate a Rayleigh backscattering (RB) interferometric beat noise circumvention architecture for the ring-based wavelength-division- multiplexed (WDM) access networks. RB can be significantly avoided since the RB and the upstream signal are traveling in opposite directions. We also analyze the performance of the proposed scheme for upgrading to 40 Gb/s and the influence of wavelength-drift at the remote node (RN).
