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.
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 and ISO National bodies.
3) IEC and ISO documents have the form of recommendations for international use and are accepted by IEC and
ISO National bodies in that sense. While all reasonable efforts are made to ensure that the technical content of
IEC and ISO documents is accurate, IEC and 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 and ISO National bodies undertake to apply IEC and ISO
documents transparently to the maximum extent possible in their national and regional publications. Any
divergence between any IEC and ISO document and the corresponding national or regional publication shall be
clearly indicated in the latter.
5) IEC and ISO do not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC and ISO marks of conformity. IEC and ISO 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 document.
7) No liability shall attach to IEC and ISO or their directors, employees, servants or agents including individual
experts and members of its technical committees and IEC and ISO National 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, use of, or reliance upon, this ISO/IEC document or any
other IEC and ISO documents.
8) Attention is drawn to the Normative references cited in this document. Use of the referenced publications is
indispensable for the correct application of this document.
9) Attention is drawn to the possibility that some of the elements of this ISO/IEC document may be the subject of
patent rights. IEC and ISO shall not be held responsible for identifying any or all such patent rights.
The main task of IEC and ISO technical committees is to prepare International Standards.
However, a technical committee may propose the publication of a Technical Report when it has
collected data of a different kind from that which is normally published as an International
Standard, for example "state of the art".
ISO/IEC TR 11801-9908, which is a Technical Report, was prepared by subcommittee 25:
Interconnection of information technology equipment, of ISO/IEC joint technical committee 1:
Information technology.
The list of all currently available parts of the ISO/IEC 11801 series, under the general title
Information technology – Generic cabling for customer premises, can be found on the IEC and
ISO websites.

INTRODUCTION
The need to support cost-efficient high-speed applications over optical fibre has resulted in the
availability of a wide variety of applications and implementation options. The available options
to support high-speed applications over optical fibre have multiplied in recent years, and the
trend towards higher speeds can be expected to continue. Innovative techniques to maximize
the useful life of installed infrastructure include the use of multi-level encoding schemes,
wavelength division multiplexing, parallel fibre transmission, and new cabled optical fibre
categories. In order to make informed decisions regarding the optimal infrastructure choices to
support deployment of high-speed applications today, and enable the optimal migration path to
higher speeds in the future, cabling system specifiers, designers and users need to have a good
understanding of the duplex and parallel application options, and their connectivity choices.
This document describes the options for high-speed applications utilizing duplex and parallel
optical fibre channels and identifies relevant migration considerations when upgrading or
planning to upgrade to higher speed applications.
