20、Tests Fibre optic connector test for transmission with applied tensile load Singlemode and multimode FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The obje

21、ct 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 Specificatio

22、ns (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-governmental organizations liaisi

23、ng 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,

24、 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

25、 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 Co

26、mmittees 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 markin

27、g 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

28、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, u

29、se 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

30、 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 61300-2-51 has been prepared by subcommittee 86B: Fibre optic interconnecting devices and passive components,

31、 of IEC technical committee 86: Fibre optics The text of this standard is based on the following documents: FDIS Report on voting 86B/2510/FDIS 86B/2544/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 public

32、ation has been drafted in accordance with the ISO/IEC Directives, Part 2. 4 61300-2-51 IEC:2007 A list of all parts of the IEC 61300 series, published under the general title Fibre optic interconnecting devices and passive components Basic test and measurement procedures, can be found on the IEC web

33、site. 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 publication.

37、art 2-51: Tests Fibre optic connector test for transmission with applied tensile load Singlemode and multimode 1 Scope This part of IEC 61300 describes a test to quantitatively assess the capability of fibre optic connector terminated fibre assemblies to withstand static tensile loads without uncoup

38、ling of the connector, physical damage to the assembly or degradation of optical performance. This test is intended to apply to fibre assemblies using any of the following: Media type 1: reinforced jacketed cordage of any diameter, Media type 2: cable with 900 m buffer coating that may or may not be

39、 reinforced or Media type 3: connectors terminating fibre with 250 m coating. 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 refe

42、omponents - Basic test and measurement procedures - Part 3-34: Examinations and measurements - Attenuation of random mated connectors 3 General description Static loads are applied in this test to the fibre or cable of the terminated assembly while the mated connector assembly is held fixed by the a

43、dapter. The loads are applied in increments parallel to and at angles to the connector axis and held for a fixed time. The sample is measured for attenuation and return loss before application of the loads, during the application of the load at each combination of load and angle and at the end of th

44、e test after the sequence of load and angle combinations have been applied. 4 Apparatus The apparatus for this test is shown in Figure 1. Fibre/cable tension is applied with weights through a capstan. The patchcord is flexed at the point of entrance to the connector plug by rotating the test arm. Th

45、e position of the connector assembly along the test arm should be adjusted so that, when the arm is at 90, the centerline 6 61300-2-51 IEC:2007 along which the fibre/cable hangs, passes through the test point. The fixture is to be designed to allow the capstan to be rotated about the axis of the sec

46、tion of fibre/cable under tension. The bracket on which the adapter is mounted is to have provision for mounting the adapter at one of the three specified angles from 0 to 135 to the axis of the connector. For transmission with applied load, angle is 0, 90 and 135 (only 90 shown) Pivot point of test
