Abstract

We propose and demonstrate a novel re-modulation scheme using inverse-return-to-zero (IRZ) signal for downstream data and differential phase shift keying (DPSK) signal for upstream data with high extinction-ratio(ER) in both directions. A 20-km-range colorless dense wavelength-division-multiplexing passive optical network (DWDM-PON) without dispersion compensation was demonstrated within 1-dB penalty for both 10-Gbit/s downstream and 10-Gbit/s upstream signals. The impact of the relative delay between the upstream signal and the downstream signal was investigated.

一种利用下游IRZ信号进行高消光比上游数据重调制的新型DWDM-PON

我们提出并演示了一种新的重调制方案，使用反向归零(IRZ)信号用于下游数据，差分相移键控(DPSK)信号用于上游数据，在两个方向上都具有高消光比(ER)。提出了一种无色散补偿的无源光网络(DWDM-PON)，适用于10gbit /s下行和10gbit /s上行信号，传输距离为20km。研究了上游信号和下游信号之间的相对延迟的影响。
