IEC 61753-021-06:2023 defines the minimum initial test and measurement requirements and severities which single-mode fibre optic connectors terminated as a pigtail or a patchcord satisfy in order to be categorised as meeting the IEC standard category OP+ (extended outdoor protected environment), as defined in IEC 61753-1. If tests were performed on the connectors terminated as pigtails or patchcords for category OP+HD and the product passed, the product will be automatically qualified or categorized as meeting the IEC standard for category OP+. If tests are performed on the connectors terminated as pigtails or patchcords for category OP+, and the product passes, the product will be automatically qualified or categorized as meeting the IEC standard for categories OP and C. This first edition cancels and replaces the first edition of IEC 61753-021-6 published in 2007. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 61753-021-6:2007: a) updated environmental category (from O to OP+), tests and their severities according to IEC 61753-1:2018; b) removed the copyright notice as it is no longer needed; c) changed title and scope to remove restrictions on attenuation and return loss grades; d) changed the term and definitions of the different types of test samples (pigtail test samples and patchcord test samples) used in the various tests to avoid confusion; e) removed the term and definition for small form factor (SFF) connectors as it is no longer used in the document; f) updated fibre naming conventions according to IEC 60793-2-50: and added provisions for B-657 fibres; g) added all the attenuation and return loss grades defined in IEC 61753-1; h) removed the static side load test; i) removed the need to perform all tests sequentially to align with other performance standards; j) added provisions for rectangular ferrule connectors; k) added Annex B for visual examination of the outer cable sheath movement of reinforced cables as an additional requirement for change of temperature, cable retention and flexing of the strain relief tests.

Si des essais ont été réalisés sur les connecteurs raccordés comme des fibres amorces ou des cordons de brassage pour la catégorie OP+HD et que le produit a satisfait aux exigences, le produit est automatiquement qualifié ou classé comme satisfaisant à la norme IEC pour la catégorie OP+. Si des essais sont réalisés sur les connecteurs raccordés comme des fibres amorces ou des cordons de brassage pour la catégorie OP+ et que le produit satisfait aux exigences, le produit est automatiquement qualifié ou classé comme satisfaisant à la norme IEC pour les catégories OP et C. Cette première édition annule et remplace la première édition de l’IEC 61753‑021‑6 parue en 2007. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’IEC 61753‑021‑6:2007: a) les essais de la catégorie d’environnement ont été mis à jour (de O à OP+) ainsi que les sévérités associées conformément à l’IEC 61753-1:2018; b) l’avis de droit d’auteur a été supprimé car il n’est plus nécessaire; c) le titre et le domaine d’application ont été modifiés afin de lever les restrictions concernant les classes d’affaiblissement et d’affaiblissement de réflexion; d) les termes et définitions des différents types d’échantillons d’essai (échantillon d’essai de fibre amorce et échantillon d’essai de cordon de brassage) utilisés dans les différents essais ont été changés afin d’éviter toute confusion; e) le terme et la définition du connecteur à faible facteur de forme (SFF) ont été supprimés car il n’est plus utilisé dans le document; f) les conventions de désignation des fibres ont été mises à jour conformément à l’IEC 60793-2-50 et des dispositions ont été ajoutées pour les fibres B-657; g) toutes les classes d’affaiblissement et d’affaiblissement de réflexion définies dans l’IEC 61753-1 ont été ajoutées; h) l’essai de charge latérale statique a été supprimé; i) la nécessité d’effectuer tous les essais de façon séquentielle a été supprimée par souci d’alignement sur les autres normes de performance; j) des dispositions ont été ajoutées pour les connecteurs à férules rectangulaires; k) l’Annexe B a été ajoutée pour l’examen visuel du mouvement de la gaine extérieure des câbles renforcés, en tant qu’exigence supplémentaire pour les essais de variations de température, de rétention de câble et de flexion du serre-câble.

Optični spojni elementi in pasivne komponente - Izvedbeni standard - 021-06. del: Konektorji za enorodovna optična vlakna, zaključeni kot repki ali povezovalne vrvice za kategorijo OP+ - Razširjeno zunanje zaščiteno okolje (IEC 61753-021-06:2023)

Standard IEC 61753-021-06:2023 določa minimalne zahteve in stopnje zahtevnosti glede začetnega preskusa ter meritev, ki jih morajo izpolnjevati konektorji za enorodovna optična vlakna, zaključeni kot repki ali povezovalne vrvice, da ustrezajo standardu IEC za kategorijo OP+ (razširjeno zunanje zaščiteno okolje), kot je opredeljeno v standardu IEC 61753-1. Če so bili preskusi izvedeni na konektorjih, zaključenih kot repki ali povezovalne vrvice, za kategorijo OP+HD in je izdelek preskus opravil, se samodejno šteje, da ustreza standardu IEC za kategorijo OP+. Če se preskusi izvedejo na konektorjih, zaključenih kot repki ali povezovalne vrvice, za kategorijo OP+ in izdelek preskus opravi, se samodejno šteje, da ustreza standardu IEC za kategoriji OP in C. Ta prva izdaja razveljavlja in nadomešča drugo izdajo standarda IEC 61753-021-6, objavljeno leta 2007. Ta izdaja je tehnično popravljena izdaja. Ta izdaja v primerjavi s standardom IEC 61753-021-6:2007 vključuje naslednje pomembne tehnične spremembe:
a) posodobitev okoljske kategorije (iz O v OP+), preskusov in njihovih stopenj zahtevnosti v skladu s standardom IEC 61753-1:2018;
b) obvestilo o avtorskih pravicah je bilo odstranjeno, ker ni več potrebno;
c) naslov in področje uporabe sta bila spremenjena; odstranjene so bile omejitve glede stopenj slabljenja in povratne izgube;
d) izrazi in definicije različnih vrst preskusnih vzorcev (preskusni vzorci z repkom in preskusni vzorci s povezovalno vrvico), ki se uporabljajo v različnih preskusih, so bili spremenjeni, da ne bi prišlo do zmede;
e) izraz in definicija za konektorje majhne velikosti (SFF) sta bila odstranjena, ker se v tem dokumentu ne uporabljata več;
f) dogovori o poimenovanju vlaken so bili posodobljeni v skladu s standardom IEC 60793-2-50 in dodane so bile določbe za vlakna B-657;
g) dodani so bili vsi razredi slabljenja in povratne izgube, opredeljeni v standardu IEC 61753-1;
h) preskus statične bočne obremenitve je bil odstranjen;
i) zaradi uskladitve z drugimi izvedbenimi standardi je bila potreba po zaporednem izvajanju vseh preskusov umaknjena;
j) dodane so bile določbe za konektorje s pravokotnimi tulkami;
k) dodan je bil dodatek B v zvezi z vizualnim pregledom premikanja zunanjega plašča ojačenih kablov kot dodatna zahteva za spremembo temperature, natezno trdnost kabelskih priključkov in preskuse spreminjanja natezne obremenitve.

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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
IEC 61753-021-06 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.
This first edition cancels and replaces the first edition of IEC 61753‑021‑6 published in 2007.

INTRODUCTION
Performance standards define the requirements for standard optical performance under a set
of specified conditions. Each standard contains a series or a set of tests and measurements
with clearly stated conditions, severities and pass/fail criteria. The series of tests, commonly
referred to as an operating service environment or performance category, is intended to be run
on a "one-off" basis to prove the product’s ability to satisfy the requirements of a specific
application, market sector or user group.
The subsequent parts of this document define those sets of tests which form each operating
service environment or performance category, and which have been standardized for
international use. A product that has been shown to meet all the requirements of a performance
standard may be declared as complying with that performance standard.
Products having the same classification from one manufacturer that satisfy a performance
standard will operate within the boundaries set by the performance standard. Intermateability
or interchangeability of products from different suppliers (having the same classification and
conforming to the same performance standard) can only be guaranteed when these products
also meet the interface standards. Only in this condition will an equivalent level of performance
be provided when they are used together (for example, in the case of optical connectors).
Conformance to a performance standard is not a guarantee of lifetime assured performance or
reliability.
Reliability testing is subjected to a separate test schedule, where the tests and severities
selected are truly representative of the requirements of this reliability test programme.
Consistency of manufacture should be maintained using a recognized quality assurance
programme whilst the reliability of the product should be evaluated using the procedures
recommended in the IEC 62005 series.
Tests and measurements should be selected from the IEC 61300 series. Where this is not
possible, the required test method should be attached as an annex to the performance standard.

FIBRE OPTIC INTERCONNECTING DEVICES AND
PASSIVE COMPONENTS – PERFORMANCE STANDARD –

Part 021-06: Single-mode fibre optic connectors terminated
as pigtails and patchcords for category OP+ –
Extended outdoor protected environment

1 Scope
This part of IEC 61753 defines the minimum initial test and measurement requirements and
severities which single-mode fibre optic connectors terminated as a pigtail or a patchcord satisfy
in order to be categorised as meeting the IEC standard category OP+ (extended outdoor
protected environment), as defined in IEC 61753-1.
If tests were performed on the connectors terminated as pigtails or patchcords for category
HD
OP+ and the product passed, the product will be automatically qualified or categorized as
meeting the IEC standard for category OP+. If tests are performed on the connectors terminated
as pigtails or patchcords for category OP+, and the product passes, the product will be
automatically qualified or categorized as meeting the IEC standard for categories OP and C.
