Fibre optics - Launch condition requirements for measuring multimode attenuation
IEC 62614:2010 describes the launch condition requirements used for measuring multimode attenuation in passive components and in installed cable plants. In this standard, the fibre types that are addressed include category A1a (50 m/125 m) and A1b (62,5 m/125 m) multimode fibres, as specified in IEC 60793-2-10. The nominal test wavelengths detailed are 850 nm and 1 300 nm. This standard may be suitable for multimode attenuation measurements for other multimode categories and/or other wavelengths, but the source condition for other categories and wavelengths are not defined here.

Fibres optiques - Exigences des conditions d'injection pour la mesure de l'affaiblissement en multimodal
La CEI 62614:2010 décrit les exigences des conditions d'injection utilisées pour la mesure de l'affaiblissement en multimodal dans les composants passifs et dans les installations câblées. Les types de fibres couverts par la présente norme sont les fibres multimodales des catégories A1a (50 m/125 m) et A1b (62,5 m/125 m), telles que spécifiées dans la CEI 60793-2-10. Les longueurs d'ondes d'essai nominales qui sont détaillées sont 850 nm et 1 300 nm. La présente norme peut être adaptée pour d'autres mesures d'affaiblissement en multimodal pour d'autres catégories multimodales et/ou d'autres longueurs d'ondes, mais la condition de source pour d'autres catégories multimodales et les longueurs d'ondes correspondantes ne sont pas définies ici.
Optična vlakna - Zahteve za meritve večrodovnega slabljenja pred začetkom proizvodnje (IEC 62614:2010)
Ta mednarodni standard opisuje zahteve za meritve večrodovnega slabljenja pred začetkom proizvodnje v pasivnih komponentah in nameščenih kablih. V tem standardu obravnavane vrste vlaken vključujejo večrodovna vlakna kategorije A1a (50 μm/125 μm) in A1b (62,5 μm/125 μm), kot je opredeljeno v IEC 60793-2-10. Podrobneje opisani nazivni preskusni valovni dolžini sta 850 nm in 1 300 nm. Ta standard je lahko primeren za meritve večrodovnega slabljenja za druge večrodovne kategorije in/ali druge valovne dolžine, vendar izvorno stanje za druge kategorije in valovne dolžine tu ni opisano. Namen teh zahtev je naslednji: - zagotoviti skladnost terenskih meritev, kadar se uporabljajo različne vrste preskusne opreme; - zagotoviti skladnost tovarniških meritev, kadar se uporabljajo različne vrste preskusne opreme; - zagotoviti skladnost terenskih meritev v primerjavi s tovarniškimi meritvami. Ta standard opisuje zahteve za stanje pred začetkom proizvodnje za optično slabljenje z uporabo virov z nadzorovanim obdanim pretokom (EF).

LAUNCH CONDITION REQUIREMENTS
FOR MEASURING MULTIMODE ATTENUATION
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 62614 has been prepared by IEC technical committee 86: Fibre
optics.
This standard cancels and replaces IEC/PAS 62614, published in 2009. This first edition
constitutes a technical revision.
The text of this standard is based on the following documents:
FDIS Report on voting
86/367/FDIS 86/368/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 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.

LAUNCH CONDITION REQUIREMENTS
FOR MEASURING MULTIMODE ATTENUATION
1 Scope
This International Standard describes the launch condition requirements used for measuring
multimode attenuation in passive components and in installed cable plants.
In this standard, the fibre types that are addressed include category A1a (50 μm /125 μm) and
A1b (62,5 μm /125 μm) multimode fibres, as specified in IEC 60793-2-10. The nominal test
wavelengths detailed are 850 nm and 1 300 nm. This standard may be suitable for multimode
attenuation measurements for other multimode categories and/or other wavelengths, but the
source condition for other categories and wavelengths are not defined here.
The purpose of these requirements is as follows:
• to ensure consistency of field measurements when different types of test equipment are
used;
• to ensure consistency of factory measurements when different types of test equipment are
used;
• to ensure consistency of field measurements when compared with factory measurements.
This standard describes launch condition requirements for optical attenuation using sources
with a controlled encircled flux (EF).
