在160 Gb/s 100 km光时分复用(OTDM)通信系统中,色散是影响系统性能的主要因素。为减小由此带来的信号波形的失真,进行了理论分析与研究,并做了相应的实验加以验证。传输链路采用混合补偿方式,精确补偿色散与色散斜率,优化传输链路色散图谱及各点工作功率,有效抑制非线性效应,实现高精度色散管理,提升系统的整体性能。使用500 GHz高速示波器,调整传输链路光纤的长度精确到10 m,并准确观测各环节实验结果。系统既没有使用前向纠错技术,也没有进行偏振模色散(PMD)补偿,仅仅通过高精度色散管理实现了160 Gb/s光时分复用信号100.25 km稳定无误码(误码率小于10-12)传输。 In 160 Gb / s 100 km optical time division multiplexing (OTDM) communication systems, dispersion is a major factor affecting system performance. In order to reduce the distortion of the signal waveform, the theoretical analysis and research are done, and the corresponding experiments are carried out to verify. The transmission link uses a hybrid compensation method to accurately compensate for the dispersion and dispersion slope, optimize the dispersion diagram of the transmission link and the working power at each point, effectively suppress the non-linear effect, achieve high-precision dispersion management, and improve the overall system performance. Use 500 GHz high-speed oscilloscope, adjust the length of the transmission link fiber to 10 m, and accurately observe the experimental results of all aspects. The system uses neither forward error correction (PMD) technology nor PMD compensation, achieving 160 Gb / s optical time-division multiplexed signals with high precision dispersion management 100.25 km stable without error (bit error rate less than 10- 12) Transmission.
