采用蒙特卡罗方法对阶跃折射率聚合物光纤的本征和外在耦合损耗进行了统计分析。与大多数现有的线性衡量单个损耗的模型不同，使用了一个全面的解析耦合损耗模型，该模型还考虑了数值孔径和芯径失配以及径向和纵向偏移量之间的相互依赖关系。作为一个典型的例子，分析了A4a.2阶跃折射率多模光纤在平衡模式分布下的耦合损耗。结果表明，与传统模型相比，耦合损耗估计的保守性大大降低，改进了链路功率预算。
The intrinsic and extrinsic coupling losses of step-index polymer optical fibers are statistically examined by Monte Carlo simulations. In contrast to most existing models that linearly scale individual losses, a comprehensive analytic coupling loss model is used that also considers the interdependencies between mismatches in numerical aperture and core diameter, as well as radial and longitudinal offsets. As a typical example, the coupling losses of A4a.2 step-index multimode fibers are analyzed for an equilibrium mode distribution. The results show considerably less conservative coupling loss estimations than with traditional models, improving link power budgeting.
