Optical fibres - Part 1-61: Measurement methods and test procedures - Polarization crosstalk
IEC 60793-1-61: 2017 establishes uniform requirements for measuring the polarization crosstalk of polarization-maintaining (PM) fibres. This document gives two methods for measuring the polarization crosstalk of PM fibres. Method A is the power ratio method, which uses the maximum and minimum values of output power at a specified wavelength, and Method B is the in-line method, which uses an analysis of the Poincaré sphere. Details of each method are described in Clause 6. Crosstalk values obtained by Methods A and B are based on different definitions. The crosstalk measured by Method A is defined as an "averaged" value over a measured wavelength range. In contrast, the crosstalk value obtained from Method B shows the "worst case" crosstalk value.

IEC 60732-1-61: 2017 définit des exigences uniformes relatives au mesurage de la diaphonie de polarisation des fibres à maintien de polarisation (PM - polarization-maintaining). Le présent document fournit deux méthodes de mesurage de la diaphonie de polarisation des fibres PM. La Méthode A est la méthode du rapport de puissance, qui utilise les valeurs maximale et minimale de puissance de sortie à une longueur d’onde spécifiée, et la Méthode B est la méthode synchronisée, qui utilise une analyse de la sphère de Poincaré. L’Article 6 détaille chacune des méthodes. Les valeurs de diaphonie obtenues par les Méthodes A et B se fondent sur des définitions différentes. La diaphonie mesurée par la Méthode A se définit comme une valeur « moyenne » dans une plage mesurée de longueurs d’ondes. Par contraste, la valeur de diaphonie obtenue avec la Méthode B est la valeur de diaphonie « la plus défavorable ». La présente version bilingue (2020-09) correspond à la version anglaise monolingue publiée en 2017-02.
Optična vlakna - 1-61. del: Metode merjenja in preskusni postopki - Polarizacija presluha (IEC 60793-1-61:2017)
Ta del standarda IEC 60793 uvaja enotne zahteve za merjenje polarizacije presluha pri vlaknih, ki ohranjajo polarizacijo (PM).
Ta dokument podaja dve metodi merjenja polarizacije presluha pri vlaknih PM. Metoda A je metoda razmerja med močjo, ki uporablja najvišje in najnižje vrednosti izhodne moči pri podani valovni dolžini, metoda B pa je notranja metoda, ki uporablja analizo Poincaréjeve sfere.
Posamezni metodi sta podrobno opisani v točki 6.
Vrednosti presluha, pridobljene z metodama A in B, temeljijo na različnih opredelitvah. Presluh, izmerjen z metodo A, je opredeljen kot »povprečna« vrednost v izmerjenem razponu valovne dolžine. V nasprotju s tem pa vrednost presluha, pridobljena z metodo B, prikazuje »najslabšo možno« vrednost presluha.
