Fibre optic interconnecting devices and passive components performance standard -- Part 101-2: Fibre management systems for category C - Controlled environment

This part of IEC 61753 deals with performance standards for parts of fibre management systems. It defines those tests and severities which form the performance or general operating service environment, and identifies those tests which are considered to be product specific. Test and severity details are given. This part of IEC 61753 contains the minimum test and measurement severities which a specific product must satisfy in order to be categorised as meeting the IEC standard, Category C - Controlled environment, as defined in Annex A of IEC 61753-1. More severe requirements may be agreed between the customer and the supplier. A product performance standard will contain a combination of those tests and measurements that are common to all products, for a particular service environment or performance category, and those that are considered specific to that particular product in that environment.

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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.
International Standard IEC 61753-100-2 has been prepared by subcommittee 86B: Fibre optic

INTRODUCTION
This Performance Standard for fibre management systems defines the requirements for
standard optical performance under a set of specified conditions. This 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 a basis to prove the product’s ability to
satisfy the requirements of a specific application, market sector or user group.
A product that has been shown to meet all the requirements of this performance standard may
be declared as complying with this performance standard. Products having the same
classification from one manufacturer that satisfy this performance standard, will operate within
the boundaries set by the performance standard. There is no guarantee that products from
different manufacturers, having the same classification and which conform to the same
performance standard, will provide an equivalent level of performance when they are used
together.
Conformance with IEC environmental policy according to IEC Guide 109 and concerning the need
to reduce the impacts on the natural environment of fibre management system products during
all phases of their life – from acquiring materials to manufacturing, distribution, use, and end-
of-life treatment (i.e. re-use, recycling and disposal) – is indicated within each product
specification.
Conformance to a performance standard demonstrates that a product has passed a design
verification test. It is not a guarantee of lifetime assured performance or reliability. Reliability
testing must be the subject of a separate test schedule, where the tests and severities selected
are such that they are truly representative of the requirements of this reliability test programme.
Consistency of manufacture should be maintained using a recognised Quality Assurance
programme whilst the reliability of a product should be evaluated using the procedures
recommended in IEC 62005.
Tests and measurements should be selected from the IEC 61300 series.

Part 101-2: Fibre management systems
for Category C – Controlled environment


1 Scope
This part of IEC 61753 deals with performance standards for parts of fibre management
systems. It defines those tests and severities which form the performance or general operating
service environment, and identifies those tests which are considered to be product specific.
Test and severity details are given.
This part of IEC 61753 contains the minimum test and measurement severities which a specific
product must satisfy in order to be categorised as meeting the IEC standard, Category C –
Controlled environment, as defined in Annex A of IEC 61753-1. More severe requirements may
be agreed between the customer and the supplier.
A product performance standard will contain a combination of those tests and measurements
that are common to all products, for a particular service environment or performance category,
and those that are considered specific to that particular product in that environment.
