23、AL COMMISSION _ FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS BASIC TEST AND MEASUREMENT PROCEDURES Part 2-33: Tests Assembly and disassembly of fibre optic mechanical splices, fibre management systems and closures FOREWORD 1) The International Electrotechnical Commission (IEC) is a wor
24、ldwide 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
25、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 committees; any IEC National Committee interested in the sub
26、ject 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 d
27、etermined 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 Co
28、mmittees. 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 wh
29、ich 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 Public
30、ation 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 n
31、ot 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 techn
32、ical 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
33、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 the elements of this IEC Publication may be the subjec
34、t of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61300-2-33 has been prepared by subcommittee 86B: Fibre optic interconnecting devices and passive components, of IEC technical committee 86: Fibre optics. This third editio
35、n cancels and replaces the second edition published in 2006. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: the inclusion of fibre management system and ancillary passive and active components as
36、well as cable management system for the incoming and outgoing optical cables. This bilingual version (2013-04) corresponds to the monolingual English version, published in 2012-07. 4 61300-2-33 IEC:2012 The text of this standard is based on the following documents: CDV Report on voting 86B/3330/CDV
37、86B/3406/RVC Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. The French version of this standard has not been voted upon. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. The list
38、of all parts in the 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
39、stability date 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. 61300-2-33 IEC:2012 5 FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE C
40、OMPONENTS BASIC TEST AND MEASUREMENT PROCEDURES Part 2-33: Tests Assembly and disassembly of fibre optic mechanical splices, fibre management systems and closures 1 Scope This part of the IEC 61300 series, evaluates the assembly and reassembly of a fibre optic mechanical splice, a fibre management s
41、ystem or a closure for a specified number of times. The test procedures simulate the following conditions which may be encountered during the components service lifetime: the ability of an optical mechanical splice to be re-installed after disassembly; the ability to re-enter fibre management system
42、s and closures, by accessing fibres and optical components and making reconfigurations without disturbing transmission in adjacent fibre circuits; verification of the sealing performance after frequent opening and closing of enclosures. 2 Normative references The following documents, in whole or in
43、part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 61300-2-22, Fibre optic interconnecting dev

Procedure A tests the ability of optical mechanical splices to be re-installed after disassembly. Procedure B tests the ability to re-enter fibre management systems and closures, by accessin
48、g fibres and optical components and making reconfigurations without disturbing transmission in adjacent fibre circuits. Procedure C verifies the sealing performance after frequent opening and closing of enclosures. The mechanical splice, fibre management system or (en)closure shall be assembled and
49、reassembled a specified number of times following the manufacturers instructions, including any specified cleaning or recovery procedure. The test shall be done according to requirements referenced in IEC 61753-1. Assembly and disassembly of the mechanical splice, fibre management system or closure shall be carried out at room temperature, unless otherwise specified. 5 Procedure 5.1 Pr
