在这里，我们提出了一种估计失准损耗的方法，该方法基于使用光纤远场模式（FFP）计算光在空间传播时的辐射角功率分布，并使用汉克尔变换简化和加速计算。该方法可以很好地估计短、中、长偏置距离的横向和纵向组合损耗。此外，同样的方法不仅可以用于描述标量损失，还可以用于描述由未对准引起的角度依赖性。我们表明，这种方法可用于升级集成到仿真软件中的传播模型中包含的连接器矩阵。通过这种方式，我们可以评估链路中不同点的错位影响，并能够预测系统级别不同布局的性能。
Here, we propose a method to estimate misalignment losses that is based on the calculation of the radiated angular power distribution as light propagates through space using the fiber far field pattern (FFP) and simplifying and speeding calculations with the Hankel transform. This method gives good estimates for combined transversal and longitudinal losses at short, intermediate and long offset distances. In addition, the same methodology can be adapted to describe not only scalar loss but also its angular dependence caused by misalignments. We show that this approach can be applied to upgrade a connector matrix included in a propagation model that is integrated into simulation software. This way, we assess the effects of misalignments at different points in the link and are able to predict the performance of different layouts at system level.
