我们提出了一种基于阵列波导光栅（AWG）的每通道10 Gbit/s全双工波分复用无源光网络（WDM-PON）。下行（DL）方向采用啁啾管理的直接调制激光，采用归零（RZ）差分相移键控（DPSK）调制技术，然后采用强度调制技术将下行信号重调制到上行（UL）方向，每通道数据速率为10 Gbit/s。在无任何光放大或色散补偿的情况下，成功地实现了WDM-PON传输操作，传输距离为25 km，每通道数据速率为10 Gbit/s，且功耗低。
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.
