FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising all
national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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
National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form of
standards, technical specifications, technical reports or guides and they are accepted by the National Committees
in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International Standards
transparently to the maximum extent possible in their national and regional standards. Any divergence between the
IEC Standard and the corresponding national or regional standard shall be clearly indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61156-6-1 has been prepared by subcommittee 46C: Wires and
symmetric cables, of IEC technical committee 46: Cables, wires, waveguides, RF connectors and
accessories for communication and signalling.
The text of this standard is based on the following documents:
FDIS Report on voting
46C/514/FDIS 46C/522/RVD
Full information on the voting for the approval of this standard can be found in the report on voting
indicated in the above table.
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 2006
At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.

MULTICORE AND SYMMETRICAL PAIR/QUAD CABLES

FOR DIGITAL COMMUNICATIONS –
Part 6-1: Symmetrical pair/quad cables with transmission

characteristics up to 600 MHz –Work area wiring –

Blank detail specification
1 Scope
This blank detail specification describes symmetrical pair/quad cables intended to construct patch,
equipment, and work area cords in digital communication systems such as ISDN, local area
networks and data communication systems using frequencies up to 600 MHz.
This specification should be used in conjunction with IEC 61156-1 and IEC 61156-6. The blank
detail specification determines the layout and style for detail specifications describing symmetrical
pair/quad cables with transmission characteristics up to 600 MHz for digital communications. Detail
specifications, based on the blank detail specification, may be prepared by a national organization,
a manufacturer, or a user.
The designation "Category 5e" is used herein to describe an enhanced Category 5 cable (see 1.1
of IEC 61156-6).
2 Normative references
The following referenced documents are indispensable for the application of this document. For
dated references, only the edition cited applies. For undated references, the latest edition of the
referenced document (including any amendments) applies.
IEC 61156-1, Multicore and symmetrical pair/quad cables for digital communications – Part 1:
Generic specification
IEC 61156-6, Multicore and symmetrical pair/quad cables for digital communications – Part 6:
Symmetrical pair/quad cables with transmission characteristics up to 600 MHz – Work area wiring
– Sectional specification
ISO/IEC 11801:2000, Information technology – Generic cabling for customer premises

3 Guidance for preparation of detail specifications
It is necessary to keep the transmission characteristics indicated in the relevant sectional
specification for the referenced category number, i.e. 5e, 6 or 7 and the characteristic impedance.
The detail specification shall be written in accordance with the layout of the blank detail
specification, which forms part of this standard.
NOTE 1 When a characteristic does not apply, then NA (for not applicable) should be entered in the appropriate space.
NOTE 2 When a characteristic applies but a specific value is not considered necessary, then NS (for not specified)
should be entered in the appropriate space. When NS is used, the appropriate requirement in the sectional specification
should apply.
