摘　　要：研究了基于高速相干光接收的100Gb/s PDM-QPSK系统的传输性能评估技术,将解析评估公式推广到不同调制格式、带宽和不规则链路跨段等应用场景中并进行系统仿真验证。仿真结果显示,该评估方法能快速、准确地计算出不同功率、调制格式和跨段配置下的系统传输性能,Q因子误差低于0.8d B。The paper studies the quality of transmission （QoT） estimation techniques based on high speed coherent optical detection of 100Gb/s PDM-QPSK system, the closed-form expressions of QoT estimation is extended to various application scenarios with different modulation format, bandwidth and non-normalized spans, and the system simulation is carried out. The simulation results show that based on the estimation method, the system transmission performance can be calculated fast and accurately for various power, modulation formats and span configurations, with the Q factor evaluation errors lower than 0.8dB.
