22、RDS Part 4: Guidelines for optical connector end-face cleaning methods for receptacle style optical transceivers FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committee

23、s). 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, Technical Specifications, Technical Reports, Publicly Available

24、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 preparatory work. International, governmental and non- governmental organiz

25、ations 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 organizations. 2) The formal decisions or agreements of IEC on technical mat

26、ters 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 recommendations for international use and are accepted by IEC Nation

27、al 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 any end user. 4) In order to promote international uniformity, IE

28、C 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 publication shall be clearly indicated in the latter. 5) IEC itsel

29、f 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 independent certification bodies. 6) All users should ensure that th

30、ey 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 personal injury, property damage or other damage of any nature

31、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 Normative references cited in this publication. Use of the referenced pu

32、blications 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 responsible for identifying any or all such patent rights. The main task

33、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 normally published as an International Standard, for example “state of the art“. IEC/T

34、R 62572-4, which is a technical report, has been prepared by subcommittee 86C: Fibre optic active components and devices, of IEC technical committee 86: Fibre optics. The text of this technical report is based on the following documents: Enquiry draft Report on voting 86C/1147/DTR 86C/1182/RVC Full

35、information on the voting for the approval of this technical report can be found in the report on voting indicated in the above table. TR 62572-4 IEC:2013(E) 5 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts in IEC 62752 series, under the gene

36、ral title Fibre optic active components and devices Reliability standards, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related t

37、o 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 colour inside logo on the cover page of this publication indicates that it contain

38、s colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer. 6 TR 62572-4 IEC:2013(E) INTRODUCTION High speed internet communication systems and subscriber systems have spread rapidly owing to the increa

39、sed capacity of data communication. In these systems, receptacle style optical transceivers such as SFP (small form factor pluggable), XFP (10-Gbps small form factor pluggable), which can be mounted and removed during transmission systems operation, are widely used. Optical receptacles of optical tr

40、ansceivers are connected to optical connector plugs of optical patch cords and optical signals are transmitted and received through these optical receptacles. Pluggable type optical transceivers are required to be low cost and of small size, and the designs are often simplified. Therefore, the inter

41、nal structure, especially the receptacle structure, tends to vary between optical transceiver manufacturers. Generally, to maintain high reliability, optical connections require cleaning of the optical connector end-face. The technical report on cleaning of optical connector plugs and optical adapto

42、rs, IEC/TR 62627-01, which was proposed by Japan, was published in August, 2010. There are, however, no standard cleaning methods for the optical receptacles of optical transceivers. It is a concern that the failure of optical transceivers due to damage and contamination of the optical receptacle en

43、d-face may lead to failure in optical network systems. This technical report is based on OITDA TP12/TP-2012.1 1_ 1References in square brackets refer to the Bibliography. TR 62572-4 IEC:2013(E) 7 FIBRE OPTIC ACTIVE COMPONENTS AND DEVICES RELIABILITY STANDARDS Part 4: Guidelines for optical connector

44、 end-face cleaning methods for receptacle style optical transceivers 1 Scope IEC/TR 62572-4, which is a technical report, provides guidelines for optical connector end- face cleaning methods for receptacle style optical transceivers. It includes details about handling receptacle style optical transc

45、eivers, internal structures of optical transceivers, information on cleaning tools and machines, applicable cleaning methods and cleaning procedures. Receptacle style optical transceivers as well as optical fibre patch cords are handled by operators and maintenance staff of optical network systems.

46、This technical report may be used as a guideline to prepare instruction manuals for the operators and maintenance staff of optical network systems. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its applicati
