我们实验演示了一个10 Gb/s的双向副载波复用（SCM）波分复用（WDM）无源光网络（PON）。我们使用数字信号处理和平方根升余弦脉冲整形技术来产生M进制正交幅度调制电信号的下行链路和上行链路传输使用简单的强度调制和直接检测光电子学，和10 GHz的收发器。该设计包括光谱预加重和偏移光学滤波，以增加商业2.2 GHz反射式半导体光放大器的光网络单元的有效带宽。我们实现了对称的10 Gb/s的传输超过20公里的单馈线PON光线路终端发射功率从1到9 dBm。我们还证明了这些SCM WDM脑桥的能力，以承受上游损害的影响。
We experimentally demonstrate a 10 Gb/s bidirectional subcarrier multiplexed (SCM) wavelength-division multiplexed (WDM) passive optical network (PON). We use digital signal processing and square-root raised cosine pulse shaping techniques to generate M-ary quadrature amplitude modulation electrical signals for the downlink and uplink transmissions using simple intensity modulation and direct detection optoelectronics, and 10 GHz transceivers. The design includes spectral preemphasis and offset optical filtering to increase the effective bandwidth of a commercial 2.2 GHz reflective semiconductor optical amplifier based optical network unit. We realize symmetric 10 Gb/s transmission over a 20 km single feeder PON with optical line terminal launch powers from 1 to 9 dBm. We also demonstrate the ability of these SCM WDM PONs to withstand the effects of upstream impairments.
