Information technology — Implementation and operation of customer premises cabling — Part 3: Testing of optical fibre cabling

ISO/IEC 14763-3:2014(E) specifies systems and methods for the inspection and testing of installed optical fibre cabling designed in accordance with premises cabling standards including ISO/IEC 11801, ISO/IEC 24764, ISO/IEC 24702 and ISO/IEC 15018. The test methods refer to existing standards-based procedures where they exist. This second edition cancels and replaces the first edition published in 2006 and its Amendment 1:2009. It constitutes a technical revision. This edition includes the following changes: - general requirements have been revised; - OTDR characterization (6.2) and requirements for cabling interface adapters and test cords have been revised; - enhanced three-test-cord reference method has been introduced; - information on optical time domain reflectometry (Annex C) has been revised; - examples of calculations of channel and permanent link limits (Annex G) have been revised and information regarding cleaning and inspection of fibre optic connections have been added (Annex H).

INFORMATION TECHNOLOGY – IMPLEMENTATION
AND OPERATION OF CUSTOMER PREMISES CABLING –

Part 3: Testing of optical fibre cabling

FOREWORD
1) ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission)
form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC
participate in the development of International Standards through technical committees established by the
respective organization to deal with particular fields of technical activity. ISO and IEC technical committees
collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in
liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have
established a joint technical committee, ISO/IEC JTC 1.
2) The formal decisions or agreements of IEC and ISO 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 and ISO member bodies.
3) IEC, ISO and ISO/IEC Publications have the form of recommendations for international use and are accepted
by IEC National Committees and ISO member bodies in that sense. While all reasonable efforts are made to
ensure that the technical content of IEC, ISO and ISO/IEC publications is accurate, IEC or ISO 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 and ISO member bodies undertake to
apply IEC, ISO and ISO/IEC publications transparently to the maximum extent possible in their national and
regional publications. Any divergence between any ISO, IEC or ISO/IEC publication and the corresponding
national or regional publication should be clearly indicated in the latter.
5) ISO and IEC do not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. ISO or IEC are 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 ISO or its directors, employees, servants or agents including individual experts
and members of their technical committees and IEC National Committees or ISO member bodies 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 of, use of, or reliance upon, this ISO/IEC
Publication or any other IEC, ISO or ISO/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 ISO/IEC Publication may be the subject of
patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
International Standard ISO/IEC 14763-3 was prepared by subcommittee 25: Interconnection
of information technology equipment, of ISO/IEC joint technical committee 1: Information
technology.
This second edition cancels and replaces the first edition published in 2006 and its
Amendment 1:2009.
This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:

---------------------- Page: 8 ----------------------
ISO/IEC 14763-3:2014  ISO/IEC 2014 – 7 –
– general requirements (Clause 5) have been revised and the concept of normalization has
been replaced by reference measurements;
– OTDR characterization (6.2) and requirements for cabling interface adapters (6.3) and test
cords have been revised and requirements for single-mode fibre test cords (6.3.4) have
been removed;
– enhanced three-test-cord reference method has been introduced (9.1.1.2);
– requirements for the attenuation measurement of cords (10.6) have been revised;
– Annex A "Launched modal distribution (LMD)" has been simplified and the new title now
reads "Launched modal conditions for testing multimode optical fibre cabling";
– visual inspection criteria for connectors have been reworked (Annex B);
– information on optical time domain reflectometry (Annex C) has been revised;
– examples of calculations of channel and permanent link limits (Annex G) have been
revised;
– and information regarding cleaning and inspection of fibre optic connections have been
added (Annex H).
A list of all parts in the ISO/IEC 14763 series, published under the general title Information
technology – Implementation and operation of customer premises cabling, can be found on
the IEC website.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
– reconfirmed,
– withdrawn,
– replaced by a revised edition, or
– amended.

IMPORTANT – The 'colour inside' logo on the cover page of this publication indicates
that it contains colours which are considered to be useful for the correct
understanding of its contents. Users should therefore print this document using a
colour printer.

INTRODUCTION
This International Standard is one of four prepared in support of International Standard
ISO/IEC 11801 and other cabling standards.
Figure 1 below shows the inter-relationship between ISO/IEC 11801 and other International
Standards and for cabling systems with related standards.

Figure 1 – Relationship of related International Standards
ISO/IEC 14763-3 details the inspection and test procedures for optical fibre cabling,
a) designed in accordance with premises cabling standards including ISO/IEC 11801,
ISO/IEC 24764, ISO/IEC 24702 and ISO/IEC 15018, and
b) installed according to the requirements and recommendations of ISO/IEC 14763-2.
Users of this International Standard should be familiar with relevant premises cabling
standards and ISO/IEC 14763-2.
The quality plan for each installation will define the acceptance tests and sampling levels
selected for that installation. Requirements and recommendations for the development of a
quality plan are described in ISO/IEC 14763-2.
NOTE JTC 1/SC 25, in cooperation with IEC/TC 86, is currently developing an overall quantitative model to
calculate total measurement uncertainty as stated in the reference planes of ISO/IEC 11801. When such a model
has been verified, it is expected to be incorporated into this standard in form of an Amendment, thereby removing
pertinent clauses currently marked “ffs” (for further study).
