24、 AND PASSIVE COMPONENTS BASIC TEST AND MEASUREMENT PROCEDURES Part 3-44: Examinations and measurements Fibre optic transceiver receptacle endface visual and automated inspection FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

25、 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 electronic fields. To this end and in addition to other activities, IEC publishes International Standards,

26、 Technical 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 preparator

27、y 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 organization

28、s. 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 reco

29、mmendations 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 a

30、ny 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 pu

31、blication 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 some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by inde

32、pendent 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 including individual experts and members of its technical committees and IEC National Committees for any

33、 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 reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normativ

34、e 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 the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsib

35、le for identifying any or all such patent rights. International Standard IEC 61300-3-44 has been prepared by subcommittee 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

36、Report on voting 86B/3424/FDIS 86B/3467/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 61300-3-44 IEC:2012 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all par

37、ts of 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 website. The committee has decided that the contents of this publication will remain unchanged until the stability date

38、indicated 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. This document is withdrawn when IEC 61300-3-35 Edition 2.0 is published. IMPORTANT The

39、 colour inside logo on the cover page of this publication indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer. 61300-3-44 IEC:2012 5 FIBRE OPTIC INTERCONNECTING DEVICES A

40、ND PASSIVE COMPONENTS BASIC TEST AND MEASUREMENT PROCEDURES Part 3-44: Examinations and measurements Fibre optic transceiver receptacle endface visual and automated inspection 1 Scope This part of IEC 61300 describes methods for quantitatively assessing the endface quality of an optic receptacle int

41、erface for single mode applications, equipped with transceivers such as SFP/XFP. Lens type and stub ferrule type interface configurations are designed for this interface, but this standard defines the end face quality of the stub ferrule type in this edition. The information is intended for use with

42、 other standards which set requirements for allowable surface defects such as scratches, pits and debris which may affect optical performance. In general, the methods described in this standard apply to 125 m cladding fibres contained within a ferrule and intended for use with sources of 2 W of inpu

43、t power. 2 Measurement 2.1 General The objective of this document is to prescribe methods for quantitatively inspecting fibre optic endfaces to determine if they are suitable for use. Two methods are described: A: video microscopy and B: automated analysis microscopy. Within each method, there are h

44、ardware requirements and procedures for both low resolution and high resolution systems. High resolution systems are to be utilized for critical examination of the glass fibre after polishing and upon incoming quality assurance. High resolution systems are typically not used during field polishing o

45、r in conjunction with multimode connectors. Low resolution systems are to be utilized prior to mating connectors for any purpose. All methods require a means for measuring and quantifying defects. There are many types of defects. Commonly used terminology would include: particles, pits, chips, scrat

46、ches, embedded debris, loose debris, cracks, etc. For practical purposes, all defects will be categorized in one of two groups. They are defined as follows: scratches: permanent linear surface features; defects: all non-linear features detectable on the fibre. This includes particulates, other debri

47、s, pits, chips, edge chipping, etc. All defects and scratches are surface anomalies. Sub-surface cracks and fractures are not reliably detectable with a light microscope in all situations and are therefore not covered within this standard. Cracks and fractures to the fibre may be detected with a lig

48、ht microscope and are generally considered a catastrophic failure. Differentiating between a scratch and all other defects is generally intuitive to a human being. However, to provide clarity, and for automated systems, scratches are defined as being less than 4 m wide, linear in nature, and with a

49、length that is at least 30 times their width. As the width dimension is not practical to measure below 3 m, these figures can be grossly estimated. Defects size is defined for method A as the diameter of the smallest circle that can encompass the entire defect. Defect size for method B can be either the actual measured surface area or 6 61300-3-44 IEC:2012 the diameter of the smallest ci
