17、zation 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 activities, IEC publishes Interna
18、tional 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 subject dealt with may participate i
19、n 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 determined by agreement between th
20、e 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 Committees. 3) IEC Publications hav
21、e 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 which they are used or for any misi
22、nterpretation 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 Publication and the corresponding natio
23、nal 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 responsible for any services c
24、arried 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 technical committees and IEC National
25、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 Publications. 8) Attention is dra
26、wn 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 of patent rights. IEC shall not
27、 be held responsible for identifying any or all such patent rights. The main task of IEC technical committees is to prepare International Standards. However, a technical committee may propose the publication of a technical report when it has collected data of a different kind from that which is norm
28、ally published as an International Standard, for example “state of the art“. IEC TR 62627-01, which is a Technical Report, has been prepared by subcommittee 86B: Fibre optic interconnecting devices and passive components, of IEC technical committee 86: Fibre optics. This second edition cancels and r
29、eplaces the first edition published in 2010. This edition constitutes a technical revision. PD IEC/TR 62627-01:2016IEC TR 62627-01:2016 IEC 2016 5 This edition includes the following significant technical changes with respect to the previous edition: a) restructure of clauses; b) addition of some te
30、rms and definitions; c) addition of information on cleaning tools and machines; d) addition of information on dust caps; e) addition of applicable cleaning tools and machines for optical connectors. The text of this Technical Report is based on the following documents: Enquiry draft Report on voting

35、bre optic connector cleaning methods 1 Scope This part of IEC 62627, which is a Technical Report, details cleaning methods for fibre optic connectors. It includes typical cleaning tools and machines, and cleaning procedures. Other cleaning methods may exist. The impact of contamination and the reaso
36、ns for connector visual inspection and cleaning are described in Annex B. This Technical Report does not address the visual inspection criteria, which are covered in IEC 61300-3-35: 2015. Optical fibre patch cords are handled by the operators and maintenance staff of optical network systems. This Te
37、chnical Report may be used as a guideline to prepare instruction manuals for those involved in optical system maintenance and operation. This Technical Report covers fibre optic connector plugs, optical adaptors, optical receptacles (excluding optical transceivers) and dust caps. Guidelines for opti
38、cal connector end-face cleaning methods for receptacle style optical transceivers are covered in IEC TR 62572-4. 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
39、edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. There are no normative references in this document. 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 Cleaners 3.1.

42、optical connector adaptors where a tape cleaning cloth at the top of the tool moves and cleans 3.1.5 reel type cleaner cassette type cleaner optical connector plug end-face cleaning tool, in which a cleaning cloth roll is packed in a cassette box, with a small window for cleaning 3.1.6 stick type cl
43、eaner swab type cleaner optical connector receptacle and optical connector adaptor end-face cleaning tool in which a cleaning cloth is attached to the top of a stick 3.2 Optical connector parts 3.2.1 bulkhead adaptor component in which two or more plugs may be mated Note 1 to entry: A bulkhead adapt
44、or has one or more alignment sleeves in which two or more ferrules are aligned. 3.2.2 dust cap cover or cap which is attached to an optical connector plug, an optical connector adaptor or an optical receptacle when the optical connector is not connected to protect it from contamination 3.2.3 exposed
45、 plug end-face EPE fibre optic plug without any fixed optical end-face protection, that may be held in the hand EXAMPLE End of a patch cord. Note 1 to entry: The ferrule is exposed to the air and is not confined within an alignment sleeve of a bulkhead adaptor or device port. The end-face of the plu
46、g is easy to access and may be brought into contact with cleaning material. 3.2.4 port open fibre optic alignment sleeve which contains a fibre optic plug end-face to which a fibre optic plug may be mated Note 1 to entry: In the case of a bulkhead adaptor, it is the open side of the adaptor after a
47、fibre optic plug has been inserted into one side. In the case of an optical device, it is the opening into which a user of the device will plug a patch cord. The mating side of a port can only be accessed through the alignment sleeve. Therefore the cleaning material shall be brought to the end-face
48、through the alignment sleeve. 3.2.5 power blocking shuttered adaptor optical adaptor that has a shutter to block optical power emitted from an optical connector plug Note 1 to entry: An optical adaptor with shutter should have a structure that, when two optical connector plugs are interfaced and the
49、 optical connector plug is removed at the shuttered side, the shutter automatically moves to block emitted optical power. There are two types of optical adaptors with shutter that have already been commercialized: one focuses on blocking the optical power and the other focuses on dust-proofness. Generally, power blocking shuttered adaptors that focus on blocking power often have a metal shutter within the optical adaptor. PD IEC/TR 62627-01:2016 8 IEC TR 62627-01:2016 IEC 2016 4 Appl
