Annotation of standard text IEC 61755-2-1-ed.2.0 :

IEC 61755-2-1:2022 defines a set of prescribed conditions for a single-mode fibre optic connection that is maintained in order to satisfy the requirements of attenuation and return loss (RL) performance in a randomly mated pair of non-angled polished physically contacting (PC) fibres. The model uses a Gaussian distribution of light intensity over the specified mode field diameter (MFD) for determination of attenuation performance grades, based on MFD mismatch and the amount of lateral and angular fibre core offsets. Attenuation and RL performance grades are defined in IEC 61755-1. This second edition cancels and replaces the first edition published in 2006. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:

  1. addition of normative references and visual requirement tables;
  2. reconsideration of the whole parts of the text to avoid misuse of the standard.
IEC 61755-2-1:2022 definit un ensemble de conditions prescrites pour maintenir une connexion optique de fibres unimodales permettant de satisfaire aux exigences de performance d’affaiblissement et d’affaiblissement de reflexion (RL) dans une paire de fibres polies en contact physique (PC) sans angle, accouplees sans choix prealable. Le modele utilise une distribution gaussienne de l’intensite lumineuse sur le diametre de champ de mode (MFD) specifie, afin de determiner les classes de performance d’affaiblissement sur la base de la discordance MFD et de la quantite de decalages lateraux et angulaires des cours de fibre. Les classes de performance d’affaiblissement et de RL sont definies dans l’IEC 61755-1. Cette deuxieme edition annule et remplace la premiere edition parue en 2006. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a) ajout de references normatives et de tableaux d’exigences visuelles;
b) reexamen de l’ensemble des parties du texte pour prevenir toute mauvaise utilisation de la norme.
