标准摘要
[中文适用范围]： 本文件提供了在1550 nm区域对B类单模光纤（见IEC 60793-2-50）非线性系数进行统一测量的指南。非线性系数的测量用于表征特定单模光纤设计，以便在系统设计中相对于功率水平和非线性光学行为引起的失真或噪声效应进行设计。 [外文原描述]： 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.
