25、ING DEVICES AND PASSIVE COMPONENTS BASIC TEST AND MEASUREMENT PROCEDURES Part 2-42: Tests Static side load for strain relief FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC Nation
26、al 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, Publicl
27、y 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- governme
28、ntal 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 t
29、echnical 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 b
30、y 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 un
31、iformity, 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.
32、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 independent certification bodies. 6) All users should en
33、sure 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
34、 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 r
35、eferenced 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. In
36、ternational Standard IEC 61300-2-42 has been prepared by subcommittee 86B: Fibre optic interconnecting devices and passive components, of IEC technical committee 86: Fibre optics. This third edition cancels and replaces the second edition published in 2005 and constitutes a technical revision. This
37、edition includes the following significant technical change with respect to the previous edition: modification of the severity according to cable configurations. 4 61300-2-42 IEC:2014 The text of this standard is based on the following documents: FDIS Report on voting 86B/3699/FDIS 86B/3721/RVD Full
38、 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 Directives, Part 2. A list of all parts of IEC 61300 series, published under the general title Fibre optic
39、interconnecting devices and passive components Basic test and measurement procedures, 1 can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the d
40、ata related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. _ 1This footnote only applies to the French title. 61300-2-42 IEC:2014 5 FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS BASIC TEST AND MEASURE
41、MENT PROCEDURES Part 2-42: Tests Static side load for strain relief 1 Scope This part of IEC 61300 specifies a test to determine the influence of a side load applied to a cord assembled with a strain relief. The intention is to simulate a static load, due to a length of fibre cable, which would typi
42、cally be experienced during service. Components should withstand side loads during optical transmission without degradation of the optical performance. Besides a boot, any feature that controls the bending radius of the fibre can be considered as strain relief. 2 Normative references The following d
43、ocuments, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 61300-1, Fibre opt

46、 procedures Part 3-4: Examinations and measurements Attenuation 3 General description The specimen is inserted into the test apparatus as shown in Figure 1. A load, equivalent to several metres of cable, is applied to the cable attached to the device under test and any changes in optical attenuation
47、 are recorded during the specified period of the test. NOTE This test is applicable only to those passive optical components where the product design incorporates fibre cable pigtails. 4 Apparatus 4.1 Load generator The load generator consists of a mass and a means of clamping the mass to the cable.
48、 The clamping shall not introduce micro- or macro-bending losses in the cable. 6 61300-2-42 IEC:2014 4.2 Holding fixture The holding fixture consists of a means to hold the device under test in a stable and representative manner. For connectors, the holding fixture shall incorporate an adaptor where
49、 required. The holding fixture shall be capable of accommodating those devices where the input and output fibre cables are co-located on the same side of the device. 4.3 Optical source and detector The optical source and detector used to measure changes in attenuation shall comply with that specified in IEC 61300-3-4.
