17、 COMMISSION _ MULTICORE AND SYMMETRICAL PAIR/QUAD CABLES FOR DIGITAL COMMUNICATIONS Part 9: Cables for channels with transmission characteristics up to 2 GHz Sectional specification FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization compri
18、sing 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 Standa
19、rds, 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 prepar
20、atory 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 organiza
21、tions. 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
22、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
23、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 regiona
24、l publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by
25、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 its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for
26、 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 Norm
27、ative 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 respo
28、nsible for identifying any or all such patent rights. International Standard IEC 61156-9 has been prepared by subcommittee 46C: Wires and symmetric cables, of IEC technical committee 46: Cables, wires, waveguides, RF connectors, RF and microwave passive components and accessories. The text of this s
29、tandard is based on the following documents: FDIS Report on voting 46C/1037/FDIS 46C/1041/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 Directive

BS IEC 61156-9:2016IEC 61156-9:2016 IEC 2016 5 A list of all parts in the IEC 61156 series, published under the general title Multicore and symmetrical pair/quad cables for digital communications, can be found on the IEC website. The committee has decided that the contents of this publica
31、tion will remain unchanged until the stability date indicated on the IEC website 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. A bilingual version of this publica
32、tion may be issued at a later date. BS IEC 61156-9:2016 6 IEC 61156-9:2016 IEC 2016 MULTICORE AND SYMMETRICAL PAIR/QUAD CABLES FOR DIGITAL COMMUNICATIONS Part 9: Cables for channels with transmission characteristics up to 2 GHz Sectional specification 1 Scope This part of IEC 61156 describes cables
33、primarily intended for the fixed part of channels as defined in ISO/IEC 11801 and in ISO/IEC TR 11801-9901 which is planned to be included in the next edition of ISO/IEC 11801-1. It covers overall screened cables with screened (X/FTP) or unscreened (X/UTP) pairs, where X stands for F, S or SF, as we
34、ll as pair-screened cables without overall screen (U/FTP). The transmission characteristics of these cables are specified up to a frequency of 2 000 MHz and at a temperature of 20 C. Two categories of cables are recognised: Category 8.1 for use in Class I according to ISO/IEC TR 11801-9901; Category
35、 8.2 for use in Class II according to ISO/IEC TR 11801-9901. These cables are intended to be used for communication channels which use at least four pairs simultaneously. The cables covered by this International Standard are intended to operate with voltages and currents normally encountered in comm
36、unication systems. While these cables are not intended to be used in conjunction with low impedance sources, e.g. the electric power supplies of public utility mains, they are intended to be used to support the delivery of low voltage remote powering applications such as IEEE 802.3af (Power over Eth
37、ernet) or further developments e.g. according to IEEE 802.3at or IEEE 802.3bt. More information on the capacity to support these applications according to the installation practices is given in IEC PAS 61156-1-4, IEC TR 61156-1-6 and ISO/IEC TR 29125. 2 Normative references The following documents,

Test methods shal
45、l be in accordance with Clause 6 of IEC 61156-1:2007/AMD1:2009, except that the length of the cable under test shall be as specified below. In addition to all requirements specified in this Clause 6, the two categories shall meet all requirements specified for the respective categories in IEC 61156-
46、5: Category 8.1: Category 6A; Category 8.2: Category 7A.NOTE By these requirements it is assured that Category 8.1 is backward compatible to Category 6Aand Category 8.2 is backward compatible to Category 7A. The computed requirements in dB, rounded to one decimal place, shall be used to determine co
47、mpliance. The tests for electrical characteristics according to 6.2 shall be carried out on a cable length of not less than 100 m, unless otherwise specified. _ 1Under consideration. BS IEC 61156-9:2016 8 IEC 61156-9:2016 IEC 2016 The tests for transmission characteristics according to 6.3 shall be
48、carried out on a cable length of 30 m, unless otherwise specified. The following parameters are proportional to length and therefore the requirements for 30 m can be calculated from the requirements per 100 m by multiplying by 0,3: phase delay and differential delay; attenuation. 6.2 Electrical char
