标准摘要
[中文适用范围]： 描述了一种表征渐变折射率多模光纤模态结构的方法。该信息对于评估光纤与激光源一起使用时的带宽性能非常有用。仅适用于多模、渐变折射率玻璃芯（约 [外文原描述]： Describes a method for characterizing the modal structure of a graded-index multimode fibre. The information is useful for assessing the bandwidth performance of a fibre when used with laser sources. Applies only to multimode, graded-index glass-core (category A1) fibres. The test method is commonly used in production and research facilities, however is not easily accomplished in the field.
