Fibre optic interconnecting devices and passive components - Basic test and measurement procedures - Part 3-7: Examinations and measurements - Wavelength dependence of attenuation and return loss of single mode components
IEC 61300-3-7:2009 describes the various methods available to measure the wavelength dependence of attenuation and return loss, of single-mode passive optical components (POC) used in fibre-optic (FO) telecommunications. This second edition cancels and replaces the first edition published in 2000. Changes from the previous edition of this standard are to reflect changes made to IEC 61300-1 and covers unidirectional and bi-directional methods of measurement.
Dispositifs d'interconnexion et composants passifs fibroniques - Méthodes fondamentales d'essais et de mesures - Partie 3-7: Examens et mesures - Dépendance par rapport à la longueur d’onde de l’affaiblissement et de l’affaiblissement de réflexion des composants unimodaux
IEC 61300-3-7:2009 décrit les diverses méthodes disponibles de mesure de la dépendance par rapport à la longueur d’onde de l’affaiblissement A(l) et de l’affaiblissement de réflexion RL(l), pour les composants optiques passifs (POC, passive optical components) unimodaux utilisés dans les télécommunications à fibres optiques. (FO). Toutefois, elle ne s'applique pas aux dispositifs à multiplexeur par répartition en longueur d'onde à forte densité (DWDM – dense wavelength division multiplexing). Les méthodes de mesure de la dépendance par rapport à la longueur d’onde de l’affaiblissement des dispositifs DWDM sont décrites dans l’IEC 61300-3-29. L’IEC 62074-1 donne une définition des types de dispositifs WDM. Trois cas de mesure sont pris en considération dans le présent document:
- Mesurage de A(l) seulement;
- Mesurage de RL(l) seulement;
- Mesurage simultané de A(l) et RL(l).
Ces mesurages peuvent être effectués dans une seule direction (unidirectionnel) ou de manière bidirectionnelle. Cette deuxième édition annule et remplace la première édition parue en 2000. Elle constitue une révision technique. Les modifications par rapport à l’édition précédente de la présente norme visent à refléter les modifications apportées à l’IEC 61300-1 et traitent des méthodes de mesure unidirectionnelles et bidirectionnelles.

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
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61300-3-7 has been prepared by subcommittee 86B: Fibre optic
interconnecting devices and passive components, of IEC technical committee 86: Fibre optics.
This second edition cancels and replaces the first edition published in 2000. It constitutes a
technical revision.
Changes from the previous edition of this standard are to reflect changes made to IEC 61300-
1 and covers unidirectional and bi-directional methods of measurement.
