摘　　要：In this paper, we propose a new structure of a centralized-light-source wavelength division multiplexed passive op- tical network （WDM-PON） utilizing inverse-duobinary-return-to-zero （inverse-duobinary-RZ） downstream and DPSK up- stream. It reuses downstream light for the upstream modulation, which retrenches lasers assembled at each optical network unit （ONU）, and ultimately cuts down the cost of ONUs a great deal. Meanwhile, a 50-km-reach WDM-PON experiment with 10-Gb/s inverse-duobinary-RZ downstream and 6-Gb/s DPSK upstream is demonstrated here. It is revealed to be a novel cost-effective alternative for the next generation access network.In this paper, we propose a new structure of a centralized-light-source wavelength division multiplexed passive op- tical network （WDM-PON） utilizing inverse-duobinary-return-to-zero （inverse-duobinary-RZ） downstream and DPSK up- stream.
