中文摘要:
我们建议一个穿的波导栅栏(美国线规) 每隧道基于 10 Gbit/s 完整的双波长部门 multiplexing 被动光网络(WDM-PON ) 。 A 啁啾有 return-to-zero ( RZ )的管理直接调制的激光调音的微分阶段移动( DPSK )调整技术为 downlink ( DL )被利用方向,然后 downlink 信号为 uplink ( UL )被重新调制有 10 Gbit/s 的数据率的方向使用紧张调整技术每隧道。有 10 Gbit/s 的数据率的成功的 WDM-PON 传播操作与低力量惩罚每在没有任何光扩大或分散赔偿的 25 km 的距离上的隧道被表明。
英文摘要:
We propose an arrayed waveguide grating(AWG)-based 10 Gbit/s per channel full duplex wavelength division multiplexing passive optical network(WDM-PON).A chirp managed directly modulated laser with return-to-zero(RZ) differential phase shift keying(DPSK) modulation technique is utilized for downlink(DL) direction,and then the downlink signal is re-modulated for the uplink(UL) direction using intensity modulation technique with the data rate of 10 Gbit/s per channel.A successful WDM-PON transmission operation with the data rate of 10 Gbit/s per channel over a distance of 25 km without any optical amplification or dispersion compensation is demonstrated with low power penalty.
