IEC TR 62285:2023 RLV包含官方IEC国际标准及其红线版本。Redline版本仅提供英文版本，为您提供了一种快速简单的方法来比较IEC官方标准与其以前版本之间的所有变化。 IEC TR 62285:2023是一份技术报告，提供了在1 550 nm区域内统一测量B类单模光纤（参见IEC 60793-2-50）非线性系数的指南。非线性系数的测量用于表征特定的单模光纤设计，用于相对于功率电平和源自非线性光学行为的失真或噪声效应的系统设计。这第三版取消并取代了2005年出版的第二版。它构成技术修订。与上一版本相比，此版本包括以下重要的技术变更: a)将尾纤的纤维类型改为B-652.D纤维或与被测纤维类型相同的纤维； b)对图A.1和公式(A.3)、(A.4)的修改； c）添加B-G.654.E纤维的示例值和推荐方法A测试条件，更新表C.1。

IEC TR 62285:2023 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.

IEC TR 62285:2023 which is a Technical Report, provides guidelines for uniform measurements of the nonlinear coefficient of class B single-mode fibres (see IEC 60793-2-50) in the 1 550 nm region. Measurements of the nonlinear coefficient are used to characterise specific single-mode fibre designs for the purpose of system design relative to power levels and distortion or noise effects derived from the nonlinear optical behaviour. This third edition cancels and replaces the second edition published in 2005. It constitutes a technical revision. This edition includes the following signification technical changes with respect to the previous revision:
a) change fibre type of pigtail to B-652.D fibre or fibre of same type with the fibre under test;
b) modifications on Figure A.1 and Formulas (A.3), (A.4);
c) add example values and recommended method A test conditions for B-G.654.E fibre, update Table C.1.
