POF商用有源器件呈现出多种设计，其中通过不同的连接器类型实现光纤耦合。发射器和接收器设计的特殊特性和公差是光纤输入和输出角功率分布变异性的背后，因此，我们认为它们是导致POF测量中通常发现的高标准偏差的原因。我们的目标是量化光纤耦合在注入端和检测端对POF链路传输参数的可变性的影响。我们分析了两种不同的源类型，并提出了一种基于实验测量参数的探测器模型。利用光纤的传播矩阵模型计算了功率损耗和频率响应的标准差，并从实验测量中提取了标准差，揭示了发射和探测条件的贡献。
POF commercial active devices present a variety of designs in which fibre coupling is achieved by different connector types. The particular characteristics and tolerances of transmitter and receiver designs are behind the variability of the fibre input and output angular power distributions, and consequently, we suggest that they are the cause of the high standard deviation usually found in POF measurements. Our aim here is to quantify the impact of the variability of the fibre coupling at the injection and the detection ends on transmission parameters of a POF link. We analysed two different source types and proposed a detector model whose parameters are based on experimental measurements. The standard deviations of power loss and frequency response are calculated using the propagation matrix model for the fibre, and also extracted from experimental measurements, revealing the contribution of both launching and detection conditions.
