Fibre optic active components and devices - Test and measurement procedures - Part 3: Optical power variation induced by mechanical disturbance in optical receptacles and transceiver interfaces
IEC 62150-3:2015 It has been found that some optical transceivers and receptacles are susceptible to fibre optic cable induced stress when side forces are applied to the mated cable-connector assembly, resulting in variations in the transmitted optical power. The purpose of this part of IEC 62150 is to define physical stress tests to ensure that such optical connections (cable and receptacle) can continue to function within specifications. This standard specifies the test requirements and procedures for qualifying optical devices for sensitivity to coupled power variations induced by mechanical disturbance at the optical ports of the device. This standard applies to active devices with optical receptacle interfaces. This standard describes the testing of transceivers for use with single-mode connectors having either 2,5 mm or 1,25 mm ferrules. This second edition cancels and replaces the first edition published in 2012 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- extension of application field to SC connector interface transceivers in addition to LC connector interface transceivers specified in the first edition as both transceiver interfaces are very important in the industry;
- addition of a new Annex E dealing with load value difference for connector type in Method A.
Keywords: fibre optic cable induced stress, power variations induced by mechanical disturbance
Composants et dispositifs actifs fibroniques - Procédures d'essais et de mesures - Partie 3: Variation de puissance optique induite par des perturbations mécaniques dans les interfaces d'embases et d'émetteurs-récepteurs optiques
IEC 62150-3:2015 On a constaté que certains émetteurs-récepteurs et embases optiques sont sensibles aux contraintes induites par les câbles fibroniques lorsque l'ensemble câble-connecteur accouplé est soumis à des forces latérales, ce qui génère des variations de la puissance optique transmise. La présente partie de l'IEC 62150 a pour objectif de définir des essais de contraintes physiques pour garantir que de telles connexions optiques (câble et embase) peuvent continuer à fonctionner conformément aux spécifications.

La présente norme s'applique aux dispositifs actifs dotés d'interfaces d'embases optiques.

Cette deuxième édition annule et remplace la première édition, parue en 2012, dont elle constitue une révision technique. La présente édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- étendue du champ d'application aux émetteurs-récepteurs avec interfaces de connecteurs SC, en plus des émetteurs-récepteurs avec interfaces de connecteurs LC spécifiés dans la première édition, dans la mesure où ces deux interfaces d'émetteurs-récepteurs sont très importantes dans l'industrie;
- ajout d’une nouvelle Annexe E traitant de la différence de valeur de charge pour le type de connecteur selon la méthode A.
Mots clés : contraintes induites par les câbles fibroniques, puissance couplée induites par des perturbations mécaniques

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
