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

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.Keywords: mode field diameter (MFD)

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

Establishes requirements for measuring the mode field diameter (MFD) of fibres. Four methods are described: (a) direct far-field scan: (b) variable aperture in the far field: (c) near-field scan: (d) bi-directional backscatter using an optical time domain reflectometer. All four methods apply to type B single-mode fibres, operating near 1310 nm or 1550 nm. The contents of the corrigendum of July 2002 have been included in this copy.

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).
