Controlled environment

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.
IEC 61753-043-02 has been prepared by subcommittee 86B: Fibre optic interconnecting
devices and passive components, of IEC technical committee 86: Fibre optics. It is an
International Standard.
The text of this International Standard is based on the following documents:

INTRODUCTION
Wavelength selective cords combine features and functions from cords as described in the
IEC 61753-12x series and from filters as described in IEC 61977. Additional information about
functional principle and application can be found in Annex D and Annex E.
The cords consist of simplex fibre optic cable terminated at each end of the cable with single-
mode fibre optic connector plugs with cylindrical ferrules. The operating wavelength range is
between 1 260 nm and 1 660 nm. Short length cords are used as test samples as the attenuation
of the cord and the temperature cycling performance will be affected by longer lengths of cable.
It is important that any qualification of a cord whose length is greater than 5 m takes these
factors into account.
The relevant requirements for the mechanical interface of connector sets are covered by
IEC 61754 (all parts). The relevant requirements for the optical interface of single-mode fibre
optical connector sets are covered by IEC 61755 (all parts). The relevant requirements for
performance of connector sets are covered by IEC 61753-1:2018. The relevant requirements
for single-mode fibres are covered by IEC 60793-2-50. The relevant requirements for cables for
cords are covered by IEC 60794-2-50.
