DS3. Characterization of POETICS Benes optical switch prototype (experimental data)

The dataset comprises experimental results from the experimental evaluation of POETICS Benes optical switch prototype, employing external transmitter and receiver based on bulk components. The transmitter consisted of an O-band optical laser source a Mach-Zehnder Modulator, driven electrically by an arbitrary waveform generator which generated NRZ and PAM-4 signals of different symbol rates, and an O-band SOA. After the optical switch, the receiver consisted of a second O-band SOA, an O-band optical filter and a photodetector. The electrical signals were captured through a real-time oscilloscope. Two different paths of within the optical switch were considered during testing, denoted as Path 1 and Path 2 respectively, with Path 1 exhibiting the best performance in terms of insertion losses. The captured signals are stored as .csv files, consisting of a voltage and a time vector. Attached with each .csv file is an image of the eye-diagram captured in real-time, through the real-time oscilloscope. The waveforms are accompanied by a “readme” file that describes more detailed technical information, as well as further details necessary for the processing of the data.本数据集收录了针对POETICS Benes光开关原型开展实验评估所获得的全部实验结果，该原型采用基于分立元器件的外部发射机与接收机架构。发射机包含O波段光激光器、马赫-曾德尔调制器（Mach-Zehnder Modulator），其电驱动信号由任意波形发生器提供，该发生器可生成不同符号速率的非归零（NRZ）与脉冲幅度调制4级（PAM-4）信号，此外发射机还搭载O波段半导体光放大器（SOA）。在光开关输出端，接收机包含第二台O波段半导体光放大器、O波段光滤波器与光电探测器。电信号通过实时示波器完成采集。测试过程中，光开关内设置了两条不同的传输路径，分别记为路径1与路径2，其中路径1的插入损耗性能最优。采集得到的信号以.csv格式文件存储，文件包含电压向量与时间向量。每个.csv文件均附带一张由实时示波器实时采集得到的眼图（eye-diagram）图像。该波形数据集还附带一份"readme"说明文件，其中包含更详细的技术信息，以及数据处理所需的全部必要细节。
