11、MMISSION _ MULTICORE AND SYMMETRICAL PAIR/QUAD CABLES FOR DIGITAL COMMUNICATIONS Part 4-1: Riser cables Blank detail specification FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC
12、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 Standards, Technical Specifications, Technical Reports, P
13、ublicly 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 preparatory work. International, governmental and non- go
14、vernmental 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 organizations. 2) The formal decisions or agreements of IE
15、C 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 recommendations for international use and are acce
16、pted 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 by any end user. 4) In order to promote internatio
17、nal 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 regional publication shall be clearly indicated in the la
18、tter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its
19、directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees 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 ar
20、ising out of the publication, use of, or reliance upon, this IEC Publication or any other 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 i
21、s 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 responsible for identifying any or all such patent rights. International Standard IEC 61156-4-1 has been prepared by subcommittee 46C: Wires and symmetric cables, o
22、f IEC technical committee 46: Cables, wires, waveguides, r.f. connectors, r.f. and microwave passive components and accessories This standard is to be read in conjunction with IEC 61156-1: 2002 and IEC 61156-4. This third edition of IEC 61156-4-1 cancels and replaces the second edition published in
23、2003. This edition constitutes a technical revision. The significant global technical change is the alignment with IEC 61156-4. 4 61156-4-1 IEC:2009(E) The text of this standard is based on the second edition and on the following documents: FDIS Report on voting 46C/885/FDIS 46C/893/RVD Full informa
24、tion on the voting for the approval of this standard can be found in the report on voting indicated in the above table. A list of all parts of the IEC 61156 series, under the general title Multicore and symmetrical pair/quad cables for digital communications, can be found on the IEC website. This pu
25、blication 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 maintenance result date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific public
26、ation. At this date, the publication will be reconfirmed; withdrawn; replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date. 61156-4-1 IEC:2009(E) 5 MULTICORE AND SYMMETRICAL PAIR/QUAD CABLES FOR DIGITAL COMMUNICATIONS Part 4-1: Riser cables

31、aracteristics indicated in the relevant sectional specification for the category number (3 or 5) 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 When a characteristic d
32、oes not apply, then NA (for not applicable) may be entered in the appropriate space. When a characteristic applies but a specific value is not considered necessary, then NS (for not specified) should be entered in the appropriate space. The numbers shown in brackets on this and the following pages c
