FOREWORD
1) ISO (International Organization for Standardization) and IEC (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. Their preparation is entrusted to technical
committees; any ISO and IEC National Committee interested in the subject dealt with may participate in this
preparatory work. International governmental and non-governmental organizations liaising with ISO and IEC
also participate in this preparation.
2) In the field of information technology, ISO and IEC have established a joint technical committee,
ISO/IEC JTC 1. Draft International Standards adopted by the joint technical committee are circulated to
national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the
national bodies casting a vote.
3) All users should ensure that they have the latest edition of this publication.
4) 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 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.
5) 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.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
ISO/IEC 14763-3 has been prepared by subcommittee 25: Interconnection of information
technology equipment, of ISO/IEC joint technical committee 1: Information technology.
This International Standard replaces ISO/IEC TR 14763-3, first edition, published in 2000, and
constitutes a technical revision.
This standard incorporates innovations and recent developments including guidance in the
proper use of uni-directional and bi-directional OTDR testing, the three-jumper method as
default test method, fibre end-face inspection and criteria for scratches, return loss values for
SC and non-SC connectors and the normative use of reference connectors. However, the most
substantial change is the application of the 2 parameters which are used to determine the two
repeatable multimode launch conditions “modal power distribution” and “coupled power ratio”.
This International Standard has been approved by vote of the member bodies, and the voting results
can be obtained from the address given on the title page.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

Part 3 of ISO/IEC 14763 details inspection and test procedures for optical fibre cabling
• designed in accordance with ISO/IEC 11801 and equivalent standards and
• installed according to the requirements and recommendations of ISO/IEC 14763-2 (under
consideration).
Users of this International Standard should be familiar with both ISO/IEC 11801 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 (under consideration).
