塑料光纤的性能受到模耦合和差分模衰减（DMA）的影响。我们建立了一种方法来估计矩阵，管理这两个影响，并允许我们区分这两个。我们得到部分定量估计这个矩阵的一个特定的梯度折射率塑料光纤（GI-POF）。我们研究的样品表现出强大的，但不完整的模式耦合超过100米的长度，而DMA在很大程度上限于一个中心线缺陷。我们表明，光纤的损耗大部分可以归因于模式之间的耦合具有相似的有效指数的模式组。
The performance of plastic optical fiber is greatly influenced by the related but distinct effects of mode coupling and differential modal attenuation (DMA). We establish a method for estimating the matrix that governs both of these effects and allows us to distinguish the two. We obtain partial quantitative estimates of this matrix for a particular graded-index plastic optical fiber (GI-POF). The sample we studied exhibited strong but incomplete mode coupling over 100-m lengths, while DMA was largely limited to a centerline defect. We show that much of the loss of the fiber can be attributed to mode coupling between mode groups with similar effective indexes.
