Optical fibres - Part 1-45: Measurement methods and test procedures - Mode field diameter

Scope

<!-- NEW! -->IEC 60793-1-45:2024 is available as <a href="https://webstore.iec.ch/publication/94215">IEC 60793-1-45:2024 RLV</a> which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.</br></br>IEC 60793-1-45:2024 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 third edition cancels and replaces the second edition published in 2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:

a) modification of the minimum distance between the fibre end and the detector for the direct far field scan (Annex A).

b) generalization of the requirement for the minimum dynamic range for all fibre types (Annex A).
