摘要。提出了一种单源光频梳的生成技术，降低了光接入网的成本。两个马赫-曾德尔调制器与一个由射频信号驱动的相位调制器级联。在10 ghz的频率间隔下，生成的40个光多载波具有良好的声噪比和最小的梳线偏移。将传统波分复用无源光网络（WDM-PON）系统光线路终端的激光阵列替换为光频梳发生器（OFCG），从而实现支持大容量WDM-PON系统的高性价比光线路终端（OLT）。在生成的40个载波中，每个载波基于差分相移键控承载10gbps数据。来自所有信道的400 Gbps多路复用数据通过25公里的光纤成功传输，功率损失可以忽略不计。下行信号的一部分用于光网络单元的上行传输，其中部署强度调制的开关键控以进行调制。基于OFCG的WDM-PON系统的理论分析与仿真结果吻合较好。用于分析WDM-PON系统中OFCG的指标包括全双工传输的功率损失、眼图和误码率。
Abstract. We propose a technique for the generation of optical frequency comb from a single source, which reduces the costs of optical access networks. Two Mach-Zehnder modulators are cascaded with one phase modulator driven by radiofrequency signals. With 10-GHz frequency spacing, the generated 40 optical multicarriers have good tone-to-noise ratio with least excursions in their comb lines. The laser array at the optical line terminal of the conventional wavelength division multiplexed passive optical network (WDM-PON) system has been replaced with optical frequency comb generator (OFCG), which may result in cost-effective optical line terminal (OLT) supporting a large-capacity WDM-PON system. Of 40 carriers generated, each carrier carries 10 Gbps data based on differential phase-shift keying. Four hundred Gbps multiplexed data from all channels are successfully transmitted through a fiber span of 25 km with negligible power penalties. Part of the downlink signal is used in uplink transmission at optical network unit where intensity-modulated on-off keying is deployed for remodulation. Theoretical analysis of the proposed WDM-PON system based on OFCG are in good agreement with simulation results. The metrics considered for the analysis of the proposed OFCG in a WDM-PON system are power penalties of the full-duplex transmission, eye diagrams, and bit error rate.
