IEC TR 61282-9:20 16（E）是一份技术报告，描述了偏振模色散（PMD）的影响和理论，并提供了PMD测量的指导。这第二版取消并取代了2006年出版的第一版。与上一版相比，第二版包括以下重大技术变更: -大部分理论已被浓缩-仅关注解释测试方法所需的内容； -符号已被删除，但缩写保留； -为避免重复实际国际标准中已有的内容，第5条中的内容已大幅减少。相反，重点是解释国际标准； -删除了国际标准中没有的测量方法；-存在对调制相移方法的显著校正，特别是关于穆勒集技术； -存在对偏振相移方法的显著校正； -给出了GINTY干涉法的证明。这个证明也扩展到固定分析器余弦转移技术； -提出了另一种固定分析仪方法。这是基于GINTY方法的证明，称为“谱微分法”； -第6条已重新命名为“限制”，并重新关注测试方法的限制。本技术报告并非工程手册； -附件已被删除； -书目的规模大大缩小； -扩大了导言，纳入了一些关于系统损伤的信息。 关键词:偏振模色散(PMD)

IEC TR 61282-9:2016(E) which is a Technical Report, describes effects and theory of polarization mode dispersion (PMD) and provides guidance on PMD measurements. This second edition cancels and replaces the first edition published in 2006. This second edition includes the following significant technical changes with respect to the previous edition:
- much of the theory has been condensed - focusing only on content that is needed to explain the test method;
- symbols have been removed, but abbreviations are retained;
- the material in the Clause 5 has been significantly reduced in an effort to avoid repeating what is already in the actual International Standards. Instead, the focus is on explaining the International Standards;
- measurement methods that are not found in International Standards have been removed;
- there are significant corrections to the modulation phase shift method, particularly in regard to the Mueller set technique;
- there are significant corrections to the polarization phase shift method;
- the proof of the GINTY interferometric method is presented. This proof also extends to the Fixed Analyser Cosine transfer technique;
- another Fixed Analyser method is suggested. This is based on the proof of the GINTY method and is called "spectral differentiation method";
- Clause 6 has been renamed "Limitations" and refocused on the limitations of the test methods. This Technical Report is not intended to be an engineering manual;
- the annexes have been removed;
- the bibliography has been much reduced in size;
- the introduction has been expanded to include some information on system impairments. Keywords: polarization mode dispersion (PMD)
