Annotation of standard text IEC 61300-3-55-ed.1.0 :

IEC 61300-3-55: 2020 provides methods for measuring the polarisation extinction ratio (PER) of single-mode, polarisation maintaining (PM) optical components based upon PM fibres. This document also provides methods for detecting the input and output orientation of the PM components principal axes as well as methods for estimating the keying accuracy, i.e. the angular misalignment between the principal axes and the mechanical reference guide key of the connectors, if these are present. IEC 61300-3-55:2020 donne les methodes pour mesurer le rapport d’extinction de polarisation (PER) des composants optiques unimodaux maintenant la polarisation (PM) bases sur des fibres PM. Le present document donne egalement les methodes pour detecter l’orientation, en entree et en sortie, des axes principaux des composants PM, ainsi que les methodes permettant d’estimer la precision du detrompage, c’est-a-dire l’erreur d’alignement angulaire entre les axes principaux et le detrompeur mecanique de reference, s’ils sont presents.
