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 60793-1-45:2017 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)
