摘　　要：为了减少测试过程中人为因素引起的误差,提高掺铒光纤放大器(EDFA)的测试质量和效率,文章基于python语言设计了能快速测试EDFA瞬态的自动测试系统。根据EDFA的工作原理和速率方程,联系光纤通信过程中产生瞬态的原因设计了合理的测试方法。利用接口总线实现了该系统可由一台计算机同时控制多台测试仪器,并且通过python语言实现仪器设备的自动化控制和"一键式"自动保存各个仪器设备的测试数据和图形。实验结果表明,该系统测试精度较高,操作方便,可扩展性好,能够充分满足用户对瞬态测试的要求。In order to reduce the errors caused by human factors and improve the quality and efficiency of Erbium-doped Optical Fiber Amplifier(EDFA) testing, an automatic testing system based on Python is designed to test EDFA transient quickly. According to the working principle and rate equation of EDFA, a reasonable test method is designed according to the cause of transient in actual optical fiber communication process. The interface bus is used to enable the system to control the multiple test instruments by one computer at the same time. Python is used to realize the automatic control of instruments and equipment, and achieve "one-key" automatic storage of test data and graphics of each instrument and equipment. Experiments show that the system has the advantages of high testing accuracy, easy operation and good scalability, which can fully meet the user’s requirements for transient testing.
