摘　　要：光纤的衰减及其均匀性是衡量光纤质量的一项重要指标,但其测试困难且很不方便,本文提出了一种分析光纤衰减及其均匀性的方法,并设计出基于该分析方法的一种测试工具,即通过利用光时域反射仪OTDR测试光纤数据,再将此数据通过GPIB接口传送给微机系统进行分析处理和保存。经实际使用证明,该工具准确而高效。The loss of fiber and its even property are vital indexes for evaluating fiber quality.But the measurement of them is difficult and not easy.This author proposes a method to analyze the loss of fiber and its even quality and designs a measuring instrument using the method.By this method,OTDR is used to measure the fiber data,which are sent to a micro-computer system through GPIB for further analysis and preservation.This instrument is proved to be accurate and efficient in practical use.
