摘　　要：针对目前PON面临的光纤故障问题,对基于OTDR的光纤定位技术进行了研究。结合OTDR的定位原理,利用光纤故障会导致OTDR测试曲线发生变化的特点,提出PON的光纤故障定位方法,并利用该方法搭建PON故障定位集中测量系统。实验平台验证了PON光纤故障定位方法的效果及局限性。Optical fiber fault location technology based OTDR is researched for the problems PON network is faced with. Based on the location principle of OTDR, the test curve of OTDR will change because of optical fiber fault, then optical fiber fault location method for PON network is proposed and central measurement system is designed. Experimental platform has been built to verify the effect and limitations of the method.
