14、wide 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 electronic fields. To this end and in addition to other ac
15、tivities, 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 committees; any IEC National Committee interested in the subje
16、ct 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 Standardization (ISO) in accordance with conditions det
17、ermined 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 has representation from all interested IEC National Comm
18、ittees. 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 accurate, IEC cannot be held responsible for the way in whic
19、h 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 regional publications. Any divergence between any IEC Publicat
20、ion 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 some areas, access to IEC marks of conformity. IEC is not
21、 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 including individual experts and members of its technic
22、al 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 reliance upon, this IEC Publication or any other IEC Pu
23、blications. 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 the elements of this IEC Publication may be the subject
24、of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. The main task of IEC technical committees is to prepare International Standards. In exceptional circumstances, a technical committee may propose the publication of a technical specification when the re
25、quired support cannot be obtained for the publication of an International Standard, despite repeated efforts, or the subject is still under technical development or where, for any other reason, there is the future but no immediate possibility of an agreement on an International Standard. Technical s
26、pecifications are subject to review within three years of publication to decide whether they can be transformed into International Standards. IEC TS 62627-09, which is a Technical Specification, has been prepared by subcommittee SC 86B: Fibre optic interconnecting devices and passive components, of
27、IEC technical committee 86: Fibre optics. 4 IEC TS 62627-09:2016 IEC 2016 The text of this technical specification is based on the following documents: Enquiry draft Report on voting 86B/3993/DTS 86B/4016/RVC Full information on the voting for the approval of this technical specification can be foun
28、d in the report on voting indicated in the above table. This document has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts in the IEC 62627 series, published under the general title Fibre optic interconnecting devices and passive components, can be found on the IEC
29、 website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be transformed into an International
30、 standard, reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date. IEC TS 62627-09:2016 IEC 2016 5 INTRODUCTION SC 86B, Fibre optic interconnecting devices and passive components, specifies several passive optical devi
31、ces. Each passive optical device has generic specification and performance specifications. Generic specifications define terms, definitions and requirements (classifications, documentations, standardization systems and so on). Some basic terms and definitions are defined and used in two or more gene
32、ric specifications. In order to harmonize terms and definitions in generic specifications, this technical specification defines terms and definitions commonly used in multiple generic specifications. 6 IEC TS 62627-09:2016 IEC 2016 FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS Vocabular

It provides the definitions which are commonly used in the generic specifications, performance standards and tests and measurement standards for passive
34、optical devices (components) prepared by SC 86B. It has the following three types of terms and definitions: basic terms and definitions; component terms and definitions; performance parameter terms and definitions. The generic specifications for passive optical devices (components) are listed in Ann
