We experimentally demonstrate the performance of a 10 Gb/s subcarrier multiplexed (SCM) wavelength-division multiplexed (WDM) passive optical network (PON) using 2.5 Gbaud 16-QAM transmission signals. Digital signal processing (DSP) and square-root raised cosine (SRRC) pulse shaping enable both the uplink and downlink channels to achieve net spectral efficiencies up to 2.8 bit/s/Hz per channel using reflective semiconductor optical amplifier (RSOA)-based optical network units (ONUs) and economical 10 GHz intensity modulation and direct detection transceivers. We characterize the system's bit error rate (BER) performance over a 20 km single feeder PON with both remote continuous-wave (CW) seeding and full-duplex transmission scenarios, assuming standard forward error correction (FEC) codes.
我们通过实验展示了一个使用2.5 Gbaud 16-QAM传输信号的10 Gb/s副载波复用（SCM）波分复用（WDM）无源光网络（PON）的性能。数字信号处理（DSP）和平方根升余弦（SRRC）脉冲整形使得上行链路和下行链路信道能够使用基于反射半导体光放大器（RSOA）的光网络单元（ONU）以及经济实惠的10 GHz强度调制和直接检测收发器，实现每信道高达2.8 bit/s/Hz的净频谱效率。我们在假设采用标准前向纠错（FEC）码的情况下，针对具有远程连续波（CW）种子注入和全双工传输场景的20 km单馈线PON，对系统的误码率（BER）性能进行了表征。
