【摘要】In this paper,we propose a new structure of a centralized-light-source wavelength division multiplexed passive optical network (WDM-PON) utilizing inverse-duobinary-return-to-zero (inverse-duobinary-RZ) downstream and DPSK upstream.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. 【总页数】4页(299-302) 【关键词】
