1、BRITISH STANDARD BS IEC 60874-14-3:1997 Connectors for optical fibres and cables Part 14-3: Detail specification for fibre optic adaptor (simplex) type SC for single-mode fibre ICS 33.180.20BSIEC 60874-14-3:1997 This British Standard, having been prepared under the directionof the Electrotechnical S
2、ector Committee, was published under the authority of the Standards Committee and comesinto effect on 15 December 1998 BSI 05-1999 ISBN 0 580 30914 2 National foreword This British Standard reproduces verbatim IEC 60874-14-3:1997 and implements it as the UK national standard. The UK participation in
3、 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 th
4、e 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 pub
5、lications 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
6、 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
7、 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. Summary of pages This document comprises a front cover, an inside fr
