2、oardand comes intoeffect on 15December1997 BSI 04-2000 ISBN 0 580 28591 X National foreword This British Standard is the English language version of EN61754-8:1997. It is identical with IEC61754-8:1997. The UK participation in its preparation was entrusted by Technical Committee EPL/86, Fibre optics
3、, to Subcommittee EPL/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 infor
4、med; 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 number60000 added to the old number. For instance, IEC2
5、7-1 has been renumbered as IEC60027-1. 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 Attention is drawn to the fact that CEN and CENELEC standards normallyinclude an annex which lists norma
6、tive references to internationalpublications with their corresponding European publications. The British Standards which implement these international or European publications may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or by
7、 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 immu
8、nity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, theENtitle page, pages 2 to 7 and a back cover.

19、 the standard interface dimensions for the type CF08 family of connectors. 2 Description The parent connector for the type CF08 connector family is a single-way plug connector which is characterized by a conical ferrule butting against a4mm diameter sphere or equivalent. It includes a push-pull coup
20、ling mechanism and a ferrule spring loaded in the direction of the optical axis. The plug has a single male key which may be used to orient and limit the relative rotation between the connector and the component to which it is mated. 3 Interfaces This standard contains the following standard interfa
21、ces: a) interface 8-1: plug connector interface; b) interface 8-2: adapter for plug/adapter/plug configuration; c) interface 8-3: receptacle connector for plug/receptacle/optical component configuration.EN61754-8:1997 4 BSI 04-2000 Figure 1 Plug connector interfaceEN61754-8:1997 BSI 04-2000 5 Table
