IEC 60793-1-45:2024
Optical fibres - Part 1-45: Measurement methods and test procedures - Mode field diameter
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).

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. Keywords: mode field diameter (MFD)
The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.
The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
