我们提出并证明了一种新的重调制方案，使用逆归零（IRZ）信号的下行数据和差分相移键控（DPSK）信号的上行数据与高的双方向的误码率（ER）。一个20公里范围内的无色密集波分复用无源光网络（DWDM-PON），没有色散补偿的10-Gbit/s的下行和10-Gbit/s的上行信号在1 dB的惩罚。研究了上行信号和下行信号之间的相对延迟的影响。
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.
