Fibre optic interconnecting devices and passive components - Basic test and measurement procedures - Part 1: General and guidance (IEC 61300-1:2022)

This part of IEC 61300 provides general information and guidance for the basic test and measurement procedures defined in the IEC 61300-2 series and IEC 61300-3 series for interconnecting devices, passive components, mechanical splices, fusion splice protectors, fibre management systems and protective housings.
This standard is used in combination with the relevant specification which defines the tests to be used, the required degree of severity for each of them, their sequence, if relevant, and the permissible performance limits. In the event of conflict between this basic standard and the relevant specification, the latter takes precedence.

Overview - EN IEC 61300-1:2022 (CLC)

EN IEC 61300-1:2022 is Part 1 of the IEC 61300 series and provides general information and guidance for basic test and measurement procedures for fibre optic interconnecting devices and passive components. Published as a CLC-adopted European standard, it is intended to be used together with the relevant IEC 61300-2 (tests) and IEC 61300-3 (examinations and measurements) specifications. Where a conflict exists, the product- or specification-level document takes precedence over this general guidance.

Keywords: EN IEC 61300-1:2022, fibre optic interconnecting devices, passive components, test and measurement procedures, IEC 61300.

Key topics and requirements

• Scope and purpose: Establishes common principles, terminology and requirements that apply across the IEC 61300 test series for connectors, mechanical splices, splice protectors, fibre management systems and protective housings.
• Terms and definitions: Standardizes vocabulary and abbreviated terms used throughout the 61300 series to ensure consistent test interpretation.
• Standard atmospheric conditions: Defines reference environmental conditions under which tests and measurements should be reported.
• Launch conditions: Guidance on launch/setup for both multimode and single-mode measurements, including special requirements for encircled flux (EF) and encircled angular flux (EAF) for certain fibre types (normative Annex A and Annex B).
• Attenuation and mode variation: Describes how launch conditions influence measured attenuation and expected variation for different multimode fibre categories.
• Calibration and round-robin: Requirements and guidance on calibration procedures and interlaboratory comparisons to maintain measurement traceability.
• Safety, graphical symbols and numerical significance: General safety notes, use of symbols and interpretation of nominal values, tolerances and ranges.

Practical applications and users

EN IEC 61300-1:2022 is used by:

• Manufacturers of fibre optic connectors, adapters, splice protectors and passive components to define test set-up and reporting consistency.
• Test laboratories and QA teams for developing test methods, calibration plans and conformity assessments.
• System integrators and installers who need to verify component performance and interpret attenuation measurements.
• Standards and compliance engineers specifying acceptance criteria and selecting the correct IEC 61300-2/-3 tests and severity levels.

Practical uses include preparing test plans, ensuring repeatable attenuation measurements, selecting appropriate launch conditions (EF/EAF templates), and harmonizing interlaboratory test results.

Related standards

• IEC 61300-2 series - Basic test procedures (specific tests)
• IEC 61300-3 series - Examinations and measurements (visual, dimensional, optical)
• IEC 60793-2-10 / IEC 60793-2-30 - Fibre product specifications referenced for fibre types
• IEC 61280, IEC 60825 - Measurement methods and laser safety referenced in the standard

EN IEC 61300-1:2022 provides the framework and guidance needed to apply the more detailed test procedures in the IEC 61300 series consistently and reliably.

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 61300-1 has been prepared by subcommittee 86B: Fibre optic interconnecting devices and

INTRODUCTION
The publications in IEC 61300 series [1] contain information on mechanical and environmental
testing procedures and measurement procedures relating to fibre optic interconnecting devices
and passive components. They are intended to be used to achieve uniformity and reproducibility
in environmental testing procedures and measurement procedures.
The term "test procedure" refers to procedures commonly known as mechanical and
environmental tests. The expressions "environmental conditioning" and "environmental testing"
refer to the environments to which components or equipment may be exposed so that an
assessment may be made of their performance under the conditions of use, transport and
storage.
The term "measurement procedure" refers to those measurements which are necessary
to assess the physical and optical characteristics of a component and may also be used before,
during or after a test procedure to measure the effects of environmental conditioning or testing.
The return loss and attenuation tests are examples of measurement procedures.
The requirements for the performance of components or equipment subjected to the test and
measurement procedures described in this document are not included. The relevant
specification for the device under test defines the allowed performance limits.
When drafting a specification or purchase contract, only those tests which are necessary for
the relevant components or equipment taking into account the technical and economic aspects
should be specified.
The mechanical and environmental test procedures are contained in IEC 61300-2 (all parts)
and the measurement procedures in IEC 61300-3 (all parts). Each test or measurement
procedure is published as a stand-alone publication so that it may be modified, expanded or
cancelled without having an effect on any other test or measurement procedure. However, it
should be noted that, where practical, reference is made to other standards as opposed to
repeating all or part of already existing standards. As an example, the cold test for fibre optic
apparatus refers to IEC 60068-2-1 [2], but it also provides other needed information such as
purpose, recommended severities and a list of items to be specified.
Multiple methods may be contained in a test or measurement procedure. As an example,
several methods of measuring attenuation are contained in the attenuation measurement
procedure.
If more than one method is contained in a test or measurement procedure, the reference method
may be identified.
The tests in this document permit the performance of components or equipment to be compared.
To assess the overall quality of a production lot, the test procedures should be applied in
accordance with a suitable sampling plan and may be supplemented by appropriate additional
tests, if necessary.
To provide tests appropriate to the different intensities of an environmental condition, some of
the test procedures have a number of degrees of severity. These different degrees of severity are
obtained by varying the time, temperature or some other determining factor separately or in
combination.
