5 IEC:2003(E) 3 INTERNATIONAL ELECTROTECHNICAL COMMISSION MULTICORE AND SYMMETRICAL PAIR/QUAD CABLES FOR BROADBAND DIGITAL COMMUNICATIONS (HIGH BIT RATE DIGITAL ACCESS TELECOMMUNICATION NETWORKS) OUTSIDE PLANT CABLES Part 1: Generic specification FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising 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 Standards, 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 preparatory work. International, governmental and nongovernmental 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 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 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 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 regional publication shall be clearly indicated in the latter. 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 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 arising 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 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 responsible for identifying any or all such patent rights. International Standard IEC has been prepared by subcommittee 46C: Wires and symmetric cables, of IEC technical committee 46: Cables, wires, waveguides, r.f. connectors, r.f. and microwave passive components and accessories. The text of this standard is based on the following documents: FDIS 46C/622/FDIS Report on voting 46C/632/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.
6 IEC:2003(E) This standard consists of this part 1, which forms the generic specification, and the other parts, which form the sectional specifications, under the general title Multicore and symmetrical pair/quad cables for broadband digital communications (high bit rate digital access telecommunication networks) Outside plant cables: Part 1: eneric specification NOTE The general design details and requirements are common to all broadband cables/wires and are applicable to Parts 2 to 5. Part 2: Sectional specification for unfilled cables Part 2-1: Blank detail specification for unfilled cables Part 3: Sectional specification for filled cables Part 3-1: Blank detail specification for filled cables Part 4: Sectional specification for aerial drop cables Part 4-1: Blank detail specification for aerial drop cables Part 5: Sectional specification for filled drop cables Part 6: Blank detail specification for filled drop cables 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 At this date, the publication will be reconfirmed; withdrawn; replaced by a revised edition, or amended.
7 IEC:2003(E) 5 MULTICORE AND SYMMETRICAL PAIR/QUAD CABLES FOR BROADBAND DIGITAL COMMUNICATIONS (HIGH BIT RATE DIGITAL ACCESS TELECOMMUNICATION NETWORKS) OUTSIDE PLANT CABLES Part 1: Generic specification 1 Scope This part of IEC is applicable to polyolefin insulated symmetrical pair/quad telecommunication cables, filled or unfilled with copper conductor intended for broadband digital communications in the local outdoor network. It provides definitions of characteristics, establishes general requirement for materials and cable construction, and details test methods and procedures. Cables are differentiated by bandwidth. They have a maximum referenced frequency of 30 MHz, 60 MHz and 100 MHz. The local cables covered by this standard are divided into two types based on cable design filled and unfilled. These cables have typically 6 to 300 pairs. The drop cables covered by this standard are divided into two types based on method of installation aerial and buried. Drop cables typically have a pair-count of 2 to 6 pairs. 2 Normative references The following referenced documents are indispensable for the application of this document.
