Abstract
We report a new approach to eliminate the extinction ratio (ER) limitation in a wavelength division multiplexed passive optical network using RZ‐ASK/DPSK remodulation format corresponding to downstream/upstream signals, respectively. A novel precoding method can improve the ER tolerance from 6 to 13 dB for a 40‐Gb/s RZ‐ASK downstream and 622‐Mb/s DPSK upstream experimental transmission with <1 dB penalty. Rayleigh and stimulated Brillouin backscattering effects are simulated and analyzed in the deployment of a bidirectional 40G Ethernet PON probably using in practical application. © 2009 Wiley Periodicals, Inc.
