单波速率不低于800Gb/s的80波超120公里新型相干光传输系统实验数据集

本数据集面向数据中心互联及中短距离大容量光传输系统的研究，聚焦于高速光通信关键技术的实验验证与性能优化。其核心应用场景包括下一代高吞吐量光纤传输架构的设计、评估与部署，为800 Gb/s级单波速率系统的工程化推进提供有力的实测支撑。 实验在超过120公里的标准单模光纤链路上，成功实现了C+L波段共120个波长信道、单波净速率不低于800 Gb/s的波分复用WDM传输。研究旨在验证系统在高符号率、多波长并发条件下的关键技术指标，重点检验宣称的单波速率与通道数量可行性，并全面评估各信道在实际传输过程中的误码率表现、传输距离适应性以及系统整体运行稳定性。 数据集主要包含以下三类关键测量信息： 1.误码率（BER）数据：针对全部120个通道，在三个不同时段采集前向纠错前误码率； 2.信号星座图：记录接收端经数字信号处理后恢复的双偏振I/Q信号二维星座图，用于分析调制质量与噪声影响； 3.光谱特性：采集WDM信号在入纤前与出纤后的光频谱分布数据，用于分析传输过程中信道间的功率变化、非线性效应及系统损耗等特性。 整体数据规模约为1 MB。This dataset is targeted at research on data center interconnection and medium-short haul high-capacity optical transmission systems, focusing on experimental verification and performance optimization of key technologies in high-speed optical communications. Its core application scenarios cover the design, evaluation and deployment of next-generation high-throughput optical fiber transmission architectures, providing robust experimental support for the engineering advancement of 800 Gb/s per-channel rate systems. The experiment successfully demonstrated wavelength division multiplexing (WDM) transmission over a standard single-mode fiber (SSMF) link longer than 120 km, with a total of 120 wavelength channels in the C+L band and a net per-channel rate of no less than 800 Gb/s. This study aims to verify the key technical indicators of the system under high symbol rate and concurrent multi-wavelength conditions, focus on validating the feasibility of the claimed per-channel rate and channel count, and comprehensively evaluate the bit error rate (BER) performance of each channel during actual transmission, transmission distance adaptability, and overall system operational stability. The dataset mainly includes three categories of key measurement data: 1. Bit Error Rate (BER) data: Pre-forward error correction (pre-FEC) BER was collected for all 120 channels at three different time periods. 2. Signal constellations: Two-dimensional constellations of the dual-polarization I/Q signals recovered by digital signal processing (DSP) at the receiver are recorded, which are used to analyze modulation quality and noise impacts. 3. Spectral characteristics: Optical spectral distribution data of WDM signals before and after fiber injection are collected, which are used to analyze characteristics such as inter-channel power variation, nonlinear effects, and system loss during transmission. The total data size is approximately 1 MB.
