摘　　要：针对传统光纤元件插回损耗测试方法效率低、易出错的缺点,基于GPIB技术开发了一种新型的光插回损耗自动测试系统。该系统通过GPIB总线实现计算机与多台测试仪器相互通信,利用VB编写测控软件实现光插回损耗的自动测试。所采集数据利用Access数据库统一管理。应用结果表明,该系统运行稳定,操作简便,具有一定的实用性和推广价值。To improve the efficiency and accuracy of the traditional insertion-return loss test method for fiber optic components, a new type of automatic test system for optic insertion-rettLrn loss based on general purpose interface bus （GPIB） technology is proposed. In the system, a computer communicates with several testers through GPIB technology. The automatic test is implemented by the control software developed by Visual Basic （VB）. The collected data are managed by the Access database. The application results show that this system runs stably and can be used conveniently. The technology and methods adopted in the system are practical and worthy of using abroad.
