BRITISH STANDARD BS IEC 60874-10-2: 1997 Connectors for optical fibres and cables Part 10-2: Detail specification for fibre optic connector type BFOC/2,5 terminated to single-mode fibre type B1 ICS 33.180.20 Licensed Copy: sheffieldun sheffieldun, na, Sun Nov 26 12:04:00 GMT+00:00 2006, Uncontrolled Copy, (c) BSI BS IEC 60874-10-2:1997 This British Standard, having been prepared under the direction of the Electrotechnical Sector Committee, was published under the authority of the Standards Committee and comes into effect on 15 May 1999 © BSI 02-2000 ISBN 0 580 30901 0 National foreword This British Standard reproduces verbatim IEC 60874-10-2:1997 and implements it as the UK national standard. The UK participation in its preparation was entrusted by Technical Committee GEL/86, Fibre optics, to Subcommittee GEL/86/2, Interconnecting devices and passive components, which has the responsibility to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European developments and promulgate them in the UK. A list of organizations represented on this subcommittee can be obtained on request to its secretary. From 1 January 1997, all IEC publications have the number 60000 added to the old number. For instance, IEC 27-1 has been renumbered as IEC 60027-1. For a period of time during the change over from one numbering system to the other, publications may contain identifiers from both systems. Cross-references The British Standards which implement international or European publications referred to in this document may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Find” facility of the BSI Standards Electronic Catalogue. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

The object of the 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, the IEC publishes International Standards. 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 organizations liaising with the IEC also participate in this preparation. The 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 the 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 National Committees. 3) The documents produced have the form of recommendations for international use and are published in the form of standards, technical reports or guides and they are accepted by the National Committees in that sense. 4) In order to promote international unification, IEC National Committees undertake to apply IEC International Standards transparently to the maximum extent possible in their national and regional standards. Any divergence between the IEC Standard and the corresponding national or regional standard shall be clearly indicated in the latter. 5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with one of its standards. 6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60874-10-2 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: 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 QC number that appears on the front cover of this publication is the specification number in the IEC Quality Assessment System for Electronic Components (IECQ). The references to clauses or subclauses of IEC 60874-1 indicated in this part apply to the third edition of IEC 60874-1.

NOTE 2To satisfy the qualification approval requirements of the detail specification there must be no failures of any in the sample groups for any test parameter. If a failure does occur this must be investigated and the cause of failure identified and corrected. The test which is affected must then be repeated using the minimum sample size stated in this detail specification. A fully documented test report and supporting data shall be prepared and must be available for inspection. Failures and the corrective action taken to eliminate failures must be documented and evidence must be presented to show that the corrective action will have no detrimental effect on the performance in any of the other tests. Design changes, as opposed to improvements in quality control, will usually be deemed to necessitate a repeat of the full qualification programme. NOTE 3Unless otherwise indicated, the test details, measurements and performance requirements are given in Table 4. NOTE 4Only group 1 tests shall be carried out using a reference connector. All other tests shall be carried out using the samples from the relevant group at random.
