Fibre optic interconnecting devices and passive components - Performance standard - Part 1-3: General and guidance for single-mode fibre optic connector and cable assembly for industrial environment, Category I

IEC 61753-1-3:2014 defines the minimum initial performance, test and measurement requirements and severities which a connector or cable assembly with single-mode fibres needs to satisfy in order to be categorized as meeting IEC Category I (industrial environment). Category I is an additional environmental category to C, U, O and E already described in IEC 61753-1. Category I is based on the MICE Table described in ISO/IEC 24702. The performance tests evaluate the product for two basic acceptance criteria: mechanical integrity and optical transmission requirements, by simulating the effects of exposure to the environment in which it will be installed, simulating installation and intervention conditions, and evaluating specified features of the product. The defined performance test procedures simulate the situation in a mated condition under use in an industrial environment. It is not the intention to simulate the situation:
- when being mated or demated;
- during the assembling of the connector;
- during transportation and storage of the connector. Reliability tests for life time expectations are not covered by this standard. Keywords: single-mode fibres, IEC Category I (industrial environment), MICE Table

Dispositifs d'interconnexion et composants passifs à fibres optiques - Norme de performance - Partie 1-3: Généralités et lignes directrices relatives aux connecteurs à fibres optiques unimodales et aux cordons en environnement industriel, Catégorie I

L'IEC 61753-1-3:2014 définit les sévérités et les exigences minimales initiales de performances, d'essais et de mesure auxquelles doit satisfaire un connecteur ou un cordon comportant des fibres unimodales, afin d'être considéré comme satisfaisant aux critères de la catégorie I (environnement industriel) de l'IEC. La catégorie I est une catégorie d'environnement qui vient s'ajouter aux catégories C, U O et E déjà décrites dans l'IEC 61753-1. La catégorie I est fondée sur le Tableau MICE décrit dans l'ISO/IEC 24702. Les essais de performances évaluent deux critères d'acceptation fondamentaux du produit: l'intégrité mécanique et les exigences de transmission optiques, en simulant les effets de l'exposition à l'environnement dans lequel le produit sera installé, en simulant l'installation et les conditions d'intervention et en évaluant les caractéristiques spécifiées du produit. Les procédures d'essais de performances définies simulent la situation dans une condition accouplée lorsque le produit est utilisé dans un environnement industriel. L'objectif n'est pas de simuler les situations suivantes:
- lorsque le connecteur est accouplé ou désaccouplé;
- pendant l'assemblage du connecteur;
- pendant le transport et le stockage du connecteur. La présente norme ne couvre pas les essais de fiabilité relatifs à l'espérance de vie. Mots clés: fibres unimodales, catégorie I (environnement industriel) de l'IEC, Tableau MICE

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.

PERFORMANCE STANDARD –
Part 1-3: General and guidance for single-mode fibre optic connector
and cable assembly for industrial environment, Category I
1 Scope

This part of IEC 61753 defines the minimum initial performance, test and measurement

requirements and severities which a connector or cable assembly with single-mode fibres

needs to satisfy in order to be categorized as meeting IEC Category I (industrial environment).

Category I is an additional environmental category to C, U, O and E already described in

IEC 61753-1. Category I is based on the MICE Table described in ISO/IEC 24702.

The performance tests evaluate the product for two basic acceptance criteria: mechanical

integrity and optical transmission requirements, by simulating the effects of exposure to the

environment in which it will be installed, simulating installation and intervention conditions,

and evaluating specified features of the product.

The defined performance test procedures simulate the situation in a mated condition under

use in an industrial environment. It is not the intention to simulate the situation:

when being mated or demated;
during the assembling of the connector;
during transportation and storage of the connector.
Reliability tests for life time expectations are not covered by this standard.

4 Industrial environment
4.1 General

Fibre optic components are frequently used in industrial environments like control stations,

power rooms or inside switch cabinets. The environmental conditions such as temperature,

dust, moisture, vibration, chemicals, impact etc. found in industrial deployment, may require

robust and sealed components to protect the optical interfaces from the effects of the

environment.
4.2 Cross reference with MICE

ISO/IEC TR 29106 classifies the environment local to a cabling system in terms of MICE

characteristics. The tests and severities in Clause 9 of this standard are intended to reflect

the M and I environment. The climatic conditions and chemical substances used are

3 3

selected from the C environment. The defined tests and severities are according to

IEC 60068-2-60.

NOTE Only a small subset of the chemical substances from the C environment are used, and these are at

different concentrations.

5 Tests
5.1 General

All test methods are in accordance with the IEC 61300 series as defined in Table A.1.

Each test defines the number of samples to be evaluated as described in Annex A. The

samples used for each test should be composed of randomly selected and previously

unstressed new samples but may also be selected from previously used samples if desired.

The connectors under test shall be terminated onto single-mode fibre per IEC 60793-2-50,

type B1.1, B1.3 or B6, depending upon the design of connector. The connector interface

standard shall meet the dimensions of the IEC 61754 series and the connector optical

interface standard shall meet the relevant requirements of the IEC 61755 series.

Unless otherwise specified, tests should be carried out under standard atmospheric

conditions according to IEC 61300-1. The optical criteria for each test shall be as defined in

Clause 9 (see also notes to Table 1).
5.2 Sample definition

For the purposes of this standard, a sample is a complete set of passive connector

components consisting of a free plug and a socket, as shown in Figure 1, or a plug coupler

plug, as shown in Figure 2. The socket may be mounted in an enclosure. This allows

demountable coupling between pairs of optical fibres.
Products under test shall be mounted and cleaned according to the manufacturer’s
instructions.

Each of the non terminated leads from the socket should be at least 3 m long so that the

splices may be located outside of the environmental test chamber.

---------------------- Page: 10 ----------------------
IEC 61753-1-3:2014 © IEC 2014 – 9 –

As a minimum requirement and if not otherwise mentioned, the tests can be run individually

as defined in Annex A.

Samples for the attenuation test shall be randomly selected and randomly mated as new

products. Samples for the return loss test are the same plugs as those selected and mated for

the attenuation test. Samples for subsequent tests may be randomly selected and randomly

mated as new products or they may be the same plugs. However, samples are reused at the

manufacturer’s own risk. In the event that this re-use causes a failure, the test may be re-run

with new samples.
6 Test report

Fully documented test reports and supporting evidence shall be prepared and available for

inspection to show that the tests have been carried out and the results are satisfactory; the

requested performance (see Table 1 for the grades) should be defined before starting the

tests.
7 Reference component
No reference components are required to perform the tests in this standard.
8 Performance requirements
8.1 General

The minimum protection level shall be IP x5 and /or IP x7 for immersion and IP 6x for dust, so

the resulting level will be IP 65 and /or IP 67. The protection level of the connector according

to IEC 60529 shall be determined before performing the tests.
8.2 Dimensions

Dimensions shall comply with the appropriate IEC interface standard as defined in the

IEC 61754 series.
8.3 Test preparation and accomplishment

Before the tests are made, the sample shall be preconditioned under standard atmospheric

conditions for testing as specified in IEC 61300-1 for a period of 2 h.

When mounting is required in a test, the adaptors shall be rigidly mounted on a specified

accessory using the specified connection methods, fixing devices and panel cut-outs.

The combination of connectors shall be maintained during the complete test sequence,

normally without un-mating the sample. When un-mating is required in a test, the end faces of

the sample shall be cleaned according to the manufacturer’s instructions.
8.4 Performance criteria
Before starting the test the following criteria shall be defined:

a) all performed tests according to the chosen performance category and performance

requirements shall be passed with all tested samples;

b) the connector end face shall comply with the end face geometry requirements of the

applicable optical interface standard as defined in the IEC 61755-3 series;

c) the optical performance levels shall meet the requirements of the designated grade as

defined in Table 1;
---------------------- Page: 11 ----------------------
