Fibre optic interconnecting devices and passive components - Basic test and measurement procedures - Part 3-29: Examinations and measurements - Spectral transfer characteristics of DWDM devices

EN IEC 61300-3-29 identifies two basic measurement methods for characterizing the spectral transfer functions of DWDM devices. The transfer functions are the functions of transmittance dependent of wavelengths. In this standard, optical attenuations are also used. The transfer functions can be used to produce measurements of insertion loss (IL), polarization dependent loss (PDL), isolation, centre wavelength, bandwidth (BW) and other optical performances.

Dispositifs d'interconnexion et composants passifs à fibres optiques - Méthodes fondamentales d'essais et de mesures - Partie 3-29: Examens et mesures - Caractéristiques de transfert spectral des dispositifs DWDM

L'IEC 61300-3-29:2014 présente deux méthodes fondamentales de mesure pour caractériser les fonctions de transfert spectral de dispositifs DWDM. Les fonctions de transfert sont les fonctions du facteur de transmission en fonction des longueurs d'onde. Dans la présente norme, les affaiblissements optiques sont également utilisés. Les fonctions de transfert peuvent être utilisées pour produire des mesures de perte d'insertion (IL), de perte dépendant de la polarisation (PDL), d'isolation, de longueur d'onde centrale, de largeur de bande (BW) et d'autres performances optiques. Cette deuxième édition annule et remplace la première édition parue en 2005. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques significatives suivantes par rapport à l'édition précédente:  - des termes et des définitions ont été ajoutés et réexaminés pour être harmonisés avec l'IEC 62074-1;  - les caractérisations du dispositif en essai ont été révisées;  - les détails devant être spécifiés ont été réexaminés. Mots clés: fonctions de transfert spectral de dispositifs DWDM, mesures de perte d'insertion (IL), de perte dépendant de la polarisation (PDL), d'isolation, de longueur d'onde centrale, de largeur de bande (BW)

Standard EN IEC 61300-3-29 določa dve osnovni merilni metodi za opredelitev spektralnih prenosnih funkcij naprav DWDM. Prenosne funkcije so funkcije prenosa, ki so odvisne od valovnih dolžin. V tem standardu se uporabljajo tudi optična zmanjšanja. Prenosne funkcije se lahko uporabijo za izvajanje meritev dodanega dušenja, dušenja, odvisnega od polarizacije, ločevanja, srednje valovne dolžine, frekvenčnega območja in drugih optičnih zmogljivosti.

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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
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 61300-3-29 has been prepared by sub-committee 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 2005. It constitutes a
technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
– terms and definitions have been added and reconsidered in order to be harmonized with
IEC 62074-1;
– characterizations of the device under test have been reviewed;

The text of this standard is based on the following documents:
FDIS Report on voting
86B/3718/FDIS 86B/3758/RVD

Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.

The list of all parts of IEC 61300 series, published under the general title, Fibre optic
interconnecting devices and passive components – Basic test and measurement procedures,
can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

Spectral transfer characteristics of DWDM devices



1 Scope
This part of IEC 61300 identifies two basic measurement methods for characterizing the
spectral transfer functions of DWDM devices.
The transfer functions are the functions of transmittance dependent of wavelengths. In this
standard, optical attenuations are also used.
NOTE In this standard, transfer functions are expressed by T(λ) and optical attenuations are expressed by A(λ).
The transfer functions can be used to produce measurements of insertion loss (IL),
polarization dependent loss (PDL), isolation, centre wavelength, bandwidth (BW) and other
optical performances.
