Annotation of standard text IEC 61753-021-03-ed.1.0 :

IEC 61753-021-03:2026 defines minimum initial test and measurement requirements and severities which single-mode fibre optic connectors terminated as a pigtail or a patchcord satisfy in order to be categorized as meeting the IEC standard category OP (outdoor protected environment), as defined in IEC 61753-1. If tests are performed on the connectors terminated as pigtails or patchcords for category OPHD, OP+ or OP+HD and the product passes these tests, the product will be automatically qualified or categorized as meeting the IEC standard for category OP. If tests are performed on the connectors terminated as pigtails or patchcords for category OP, and the product passes these tests, the product will be automatically qualified or categorized as meeting the IEC standard for category C or CHD. This first edition cancels and replaces the first edition of IEC 61753-021-3 published in 2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) update of environmental categories (from U to OP), tests and their severities in accordance with IEC 61753-1; b) changes in the terms and definitions of the different types of test samples (pigtail test samples and patchcord test samples) used in the various tests to avoid confusion; c) update of fibre naming conventions in accordance with IEC 60793-2-50 and addition of provisions for B-657 fibres; d) addition of all the attenuation and return loss grades defined in IEC 61753-1; e) deletion of the static side load test; f) addition of provisions for rectangular ferrule connectors; g) addition of the fibre optic connector proof test with static load – side pull; h) update of the flexing of the strain relief test to use change of attenuation instead of transient loss; i) addition of Annex B for visual examination of the outer cable sheath movement of reinforced cables as an additional requirement for change of temperature, cable retention and flexing of the strain relief tests. L’IEC 61753-021-03:2026 definit les exigences minimales d’essai et de mesures initiales et les severites auxquelles les connecteurs fibroniques unimodaux raccordes a des fibres amorces et des cordons de brassage satisfont pour etre classes comme repondant a la categorie OP (environnement exterieur protege) de la norme IEC, telle qu’elle est definie dans l’IEC 61753-1. Si les essais sont effectues sur les connecteurs raccordes a des fibres amorces et des cordons de brassage pour la categorie OPHD, OP+ ou OP+HD et que le produit satisfait aux essais, il est automatiquement qualifie ou classe comme repondant a la categorie OP de la norme IEC. Si les essais sont effectues sur les connecteurs raccordes a des fibres amorces et des cordons de brassage pour la categorie OP, et que le produit satisfait aux essais, il est automatiquement qualifie ou classe comme repondant a la categorie C ou CHD de la norme IEC. Cette premiere edition annule et remplace la premiere edition de lIEC 61753-021-3 parue en 2012. Cette edition constitue une revision technique.Cette edition inclut les modifications techniques significatives suivantes par rapport a ledition precedente: a) mise a jour des categories d’environnement (de U a OP), des essais et de leurs severites conformement a l’IEC 61753-1; b) modification des termes et definitions des differents types d’echantillons d’essai (echantillons d’essai de fibres amorces et echantillons d’essai de cordons de brassage) utilises dans les differents essais afin d’eviter toute confusion; c) mise a jour des conventions de nommage des fibres, conformement a l’IEC 60793­2­50 et ajout de dispositions pour les fibres B-657; d) ajout de toutes les classes d’affaiblissement et d’affaiblissement de reflexion definies dans l’IEC 61753-1; suppression de l’essai de charge laterale statique; f) ajout de dispositions pour les connecteurs a ferule rectangulaire; g) ajout de l’essai de resistance des connecteurs fibroniques avec charge statique – traction laterale; h) mise a jour de la flexion de lessai des serre-cables pour utiliser les variations daffaiblissement a la place des pertes transitoires; i) ajout de l’Annexe B relative a l’examen visuel du mouvement de la gaine exterieure du cable des cables renforces comme exigence supplementaire pour les essais de variations de temperature, de retention du cable et de flexion des serre-cables.
