19、E COMPONENTS BASIC TEST AND MEASUREMENT PROCEDURES Part 2-49: Tests Connector installation test FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of

20、 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 (P

21、AS) 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 liaising wi

22、th 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 n

23、early 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 t

24、hat 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 Committ

25、ees 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 pro

26、cedure 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 ag

27、ents 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

28、, 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

29、 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 61300-2-49 has been prepared by subcommittee 86B: Fibre optic interconnecting devices and passive components, of I

30、EC technical committee 86: Fibre optics. The text of this standard is based on the following documents: FDIS Report on voting 86B/2508/FDIS 86B/2542/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. 4 61300-2-49 IE

36、2-49: Tests Connector installation test 1 Scope This part of IEC 61300 provides a test to determine that a connector is capable of functioning when installed in a cabinet or other enclosure in which the space available is limited. 2 Normative references The following referenced documents are indispe

37、nsable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

39、measurement procedures Part 3-4: Measurements Attenuation 3 General description The specimen is mounted into the test apparatus as shown in Figure 1. A panel is brought parallel to the mounting fixture and change in loss is measured. 4 Apparatus 4.1 Mounting fixture The mounting fixture is a vertica

40、l surface that consists of a means to hold the device under test in a stable and representative manner. For connectors the mounting fixture will incorporate an adaptor. The mounting fixture shall be capable of accommodating those devices where the input and output fibre cables are co-located on the

41、same side of the device. For connectors, where an adapter is used to connect two connectors, if there is more than one way to mount the adapter in the fixture, the adapter should be mounted so as to maximize the distance from the end of the connector to the panel. 4.2 Panel The panel consists of a f

42、lat surface that is brought parallel to the mounting fixture to simulate a cabinet door closing on the installed device. 6 61300-2-49 IEC:2007 To detector To optical source Mounting fixture Device under test PanelFibre cable For example, 70 mm IEC 952/07 Figure 1 Example of the connector installatio

43、n test 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. See Table 1 for preferred wavelengths. Table 1 Preferred wavelengths Singlemode 1 310 nm and 1 550 nm, optional 1 625 nm Multimode 850 nm a

44、nd 1300 nm 5 Procedure 5.1 Preparation of specimens Prepare the specimens according to the manufacturers instructions or as specified in the relevant specification. The device under test shall be terminated with a sufficient length of fibre cable to facilitate interfacing with the optical source and

45、 detector. 5.2 Pre-conditioning Pre-condition the device under test for 2 h at the standard test conditions as given in IEC 61300-1, unless otherwise specified in the relevant specification. Measure and record the attenuation of the device under test. 61300-2-49 IEC:2007 7 5.3 Initial measurements C

46、omplete initial examinations and measurements on the specimen as required by the relevant specification. 5.4 Conditioning Clean the connector according to the manufacturers instructions. The body of the specimen shall be mounted in a representative manner onto the mounting fixture (see Figure 1). Th

47、e jumper cable that exits from the device under test is to be dressed so that about one metre of cable is supported by the end of the connector boot. 5.5 Measuring the attenuation Re-measure the attenuation to ensure that the fixturing has not affected the cables attenuation. 5.6 Applying the panel

48、Bring the panel to a position that is parallel to the mounting fixture surface and at a distance from the mounting panel as illustrated in Figure 1. 5.7 Monitoring attenuation with the panel applied The attenuation of the specimen shall be measured with the panel in position, as described in IEC 613

49、00-3-4, unless otherwise specified in the relevant specification. Any deviation in the device attenuation from that measured in 5.5 shall be considered attributable to the cable/device interface, or to fibre-to-fibre interfaces in the device. 5.8 Final measurements and examinations On completion of the test, remove the panel an
