23、ernational 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 ele

24、ctronic 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 committ

25、ees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for

26、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 h

27、as 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 accur

28、ate, 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 regiona

29、l publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in so

30、me areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 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

31、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

32、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 t

33、he 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 62150-3 has been prepared by subcommittee 86C: Fibre optic systems and active devices, of IEC technical committee 86: F

34、ibre optics. This second edition cancels and replaces the first edition published in 2012 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: extension of application field to SC connector interface transceiver

35、s in addition to LC connector interface transceivers specified in the first edition as both transceiver interfaces are very important in the industry; addition of a new Annex E dealing with load value difference for connector type in Method A. IEC 62150-3:2015 IEC 2015 5 The text of this standard is

36、 based on the following documents: FDIS Report on voting 86C/1311/FDIS 86C/1330/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 publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

37、 A list of all parts in the IEC 62150 series, published under the general title Fibre optic active components and devices Test and measurement procedures, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date i

38、ndicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date. IMPORTANT The co

40、DEVICES TEST AND MEASUREMENT PROCEDURES Part 3: Optical power variation induced by mechanical disturbance in optical receptacles and transceiver interfaces 1 Scope It has been found that some optical transceivers and receptacles are susceptible to fibre optic cable induced stress when side forces ar

41、e applied to the mated cable-connector assembly, resulting in variations in the transmitted optical power. The purpose of this part of IEC 62150 is to define physical stress tests to ensure that such optical connections (cable and receptacle) can continue to function within specifications. This stan

42、dard specifies the test requirements and procedures for qualifying optical devices for sensitivity to coupled power variations induced by mechanical disturbance at the optical ports of the device. This standard applies to active devices with optical receptacle interfaces. This standard describes the

43、 testing of transceivers for use with single-mode connectors having either 2,5 mm or 1,25 mm ferrules. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition ci

46、the purposes of this document, the following terms and definitions apply. 3.1.1 wiggle mechanical disturbances that induce coupled optical power variation in the optical receptacle and transceiver interface IEC 62150-3:2015 IEC 2015 7 3.1.2 wiggle loss variation in coupled output power (with respect

47、 to a no-load, non-rotated measurement) induced in an optical module or receptacle when the mated connector is laterally stressed 3.2 Abbreviations DUT device under test LOS loss of signal Rx receiver Tx transmitter 4 Measurement consideration 4.1 Multiple test methods Since the wiggle loss mechanis

48、ms are categorized into two different cases, Case A and B, this standard defines two measurement methods, Method A and B, as shown in Table 1. Method A and B are applicable to the tests for the mechanical endurance of transceivers under wiggle Case A and B, respectively. Table 1 Multiple test method
