19、NTERCONNECTING DEVICES AND PASSIVE COMPONENTS BASIC TEST AND MEASUREMENT PROCEDURES Part 2-50: Tests Fibre optic connector proof test with static load Singlemode and multimode FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising a

20、ll 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, T

21、echnical 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

22、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 organizations.

23、 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 recomm

24、endations 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

25、 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 publ

26、ication 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.

27、 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

28、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 app

29、lication 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 61300-2-50 has been prepared by su

30、bcommittee 86b Fibre optic interconnecting devices and passive components, of IEC technical committee 86: Fibre optics. The text of this standard is based on the following documents: FDIS Report on voting 86B/2509/FDIS 86B/2543/RVD Full information on the voting for the approval of this standard can

31、 be found in the report on voting indicated in the above table.

36、TING DEVICES AND PASSIVE COMPONENTS BASIC TEST AND MEASUREMENT PROCEDURES Part 2-50: Tests Fibre optic connector proof test with static load Singlemode and multimode 1 Scope This part of IEC 61300 describes a test to quantitatively assess the capability of connector terminated patchcord cable assemb

37、lies to withstand static loads without uncoupling of the connector, physical damage to the assembly or permanent degradation of optical performance. This test is intended to apply to terminated reinforced jacketed cable of any diameter, both singlemode and multimode. 2 Normative references The follo

41、ted connectors 3 General description Static loads are applied to the cable of a patchcord assembly at 0 (straight pull) and at 90 (side pull) to the connector axis and held for a fixed time, while the mated connector assembly is held fixed by the adapter. The sample is examined and measured for atte

42、nuation and return loss before and after each load is applied. 4 Apparatus The apparatus for this test is shown in Figure 1. The patchcord 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. The position

43、of the connector assembly along the test arm should be adjusted so that, when the arm is at 90, the centerline along which the 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 section of cable under tension. 6 61300-2-5

44、0 IEC:2007 The bracket on which the adapter is mounted is to have provision for mounting the adapter at angles of 0 and 90 to the axis of the connector.
