Application guidelines for nonlinear coefficient measuring methods

IEC TR 62285:2023 is available as IEC TR 62285:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC TR 62285:2023 which is a Technical Report, provides guidelines for uniform measurements of the nonlinear coefficient of class B single-mode fibres (see IEC 60793-2-50) in the 1 550 nm region. Measurements of the nonlinear coefficient are used to characterise specific single-mode fibre designs for the purpose of system design relative to power levels and distortion or noise effects derived from the nonlinear optical behaviour. This third edition cancels and replaces the second edition published in 2005. It constitutes a technical revision. This edition includes the following signification technical changes with respect to the previous revision:
a) change fibre type of pigtail to B-652.D fibre or fibre of same type with the fibre under test;
b) modifications on Figure A.1 and Formulas (A.3), (A.4);
c) add example values and recommended method A test conditions for B-G.654.E fibre, update Table C.1.

Guide d'application pour les méthodes de mesure du coefficient de non-linéarité

IEC TR 62285:2023 est disponible sous forme de IEC TR 62285:2023 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.
