IEC 60793-1-42:2013建立了测量光纤色散的统一要求，从而有助于检查用于商业目的的光纤和电缆。第三版取消并取代了2007年出版的第二版。它构成技术修订。与上一版相比，此版本包括以下重大技术变更: -包括B6类单模光纤； -删除测试方法D（干涉法）。 关键词:光纤色散； 本出版物应与IEC 60793-1-1:20 08一起阅读。

IEC 60793-1-42:2013 establishes uniform requirements for measuring the chromatic dispersion of optical fibre, thereby assisting in the inspection of fibres and cables for commercial purposes. This third edition cancels and replaces the second edition, published in 2007. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- the inclusion of category B6 single-mode fibres;
- the deletion of test method D (interferometry). Keywords: chromatic dispersion of optical fibre

This publication is to be read in conjunction with IEC 60793-1-1:2008.
