纤维光学互连器件和无源元件.基本试验和测量程序.第3-2部分:检查和测量.单模纤维光学器件的偏振损耗相关性

[中文适用范围]： 本部分 IEC 61300 规定了测量单模光纤器件损耗随偏振变化而变化的方法。该程序侧重于使用固定波长源的测量；因此，该程序适用于其单波长特性可代表较宽波长带特性的器件。此类器件的典型例子包括单模互连器件和无源组件，包括连接器、熔接点、分支器件、衰减器、隔离器和开关。观察到的传输损耗最大变化称为偏振相关损耗（PDL）。本标准适用于宽带器件，不适用于窄带器件（如滤波器和复用器）。读者可参考 IEC 61300-3-29 进行此类测量。 [外文原描述]： IEC 61300-3-2:2009 specifies measurement methods to determine the dependence of loss in a single-mode fibre optic device to changes in polarization. This procedure focuses on measurements with a fixed wavelength source; therefore, this procedure is applicable to devices whose properties at a single wavelength can represent those over the broader wavelength band. Typical examples of such devices are single-mode interconnecting devices and passive components, including connectors, splices, branching devices, attenuators, isolators, and switches. The maximum observed variation in transmission loss is referred to as polarization-dependent-loss (PDL). This standard applies to broadband devices and not to narrow-band devices like filters and multiplexers. The reader is referred to IEC 61300-3-29 for such measurements. This third edition cancels and replaces the second edition published in 1999. It constitutes a technical revision. The main changes with respect to the previous edition are: this edition includes both the all-states method of the previous edition as well as the Mueller matrix method from IEC 61300-3-12.
