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

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.
