IEC 60793-1-45:2017 RLV contains both the official IEC International Standard and its Redline version. The Redline version is not an official document, it 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 60793-1-45:2017 establishes uniform requirements for measuring the mode field diameter (MFD) of single-mode optical fibre, thereby assisting in the inspection of fibres and cables for commercial purposes.  This second edition cancels and replaces the first edition published in 2001. This edition constitutes a technical revision.  This edition includes the following significant technical changes with respect to the previous edition:
- improvement of the description of measurement details for B6 fibre,
- correction of Equations (1), (2), (5) and (6),
- correction of Table E.1, Table E.2 and Table E.3.
