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 61753-101-03 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 IEC 61753-101-3 the first edition published in 2006. This

edition constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

edition:
a) the terms and definitions have been updated according to IEC 61753-1:2018 and
IEC 61756-1:2019;
b) the test severities have been updated according to IEC 61753-1:2018;

c) detailed material tests for mould growth (IEC 60068-2-10) and UV light exposure (ISO 4892-

3) have been added;

d) the detailed transport performance requirements have been removed;

e) IEC 60793-2-50 subcategory B-657 fibres for test samples in Annex A has been added.

The text of this International Standard is based on the following documents:

This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in

accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available

at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are

described in greater detail at www.iec.ch/standardsdev/publications.

A list of all parts in the IEC 61753 series, published under the general title Fibre optic

interconnecting devices and passive components performance standard, can be found on the

IEC website.

The committee has decided that the contents of this document will remain unchanged until the

stability date indicated on the IEC website under webstore.iec.ch in the data related to the

specific document. At this date, the document will be
• reconfirmed,

FIBRE OPTIC INTERCONNECTING DEVICES AND
PASSIVE COMPONENTS PERFORMANCE STANDARD –
Part 101-03: Fibre management systems for category OP –
Outdoor protected environment
1 Scope

This part of IEC 61753 contains the minimum tests, test severities and measurement

requirements which a fibre management system need to meet in order to be categorised as

meeting the IEC standard, category OP – Outdoor Protected environment, as defined in

IEC 61753-1.

This performance standard for fibre management systems defines the requirements for

standard optical performance under a set of specified conditions. It 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 a basis to prove the product’s ability to satisfy the requirements of

a specific application, market sector or user group.
