3、ean Electronic Components Committee (CECC) of the European Committee for Electrotechnical Standardization (CENELEC). The UK participation in its preparation was entrusted by Technical Committee EPL/86, Fibre optics, to Subcommittee EPL/86/2, Interconnecting devices and passive components, which has

4、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 th

5、e UK. A list of organizations represented on this subcommittee can be obtained on request to its secretary. Cross-references Attention is drawn to the fact that CEN and CENELEC standards normally include an annex which lists normative references to international publications with their corresponding

6、 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 using the “Find” facility of the BSI Standards Electronic Catalogue.

7、 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. Summary of pages This document comprises

IV, in order to permit the issue of more than nine sectional specifications. The approved numbering system applicable to

22、fibre optic connector specifications is illustrated in the following diagram:EN186290:1997 4 BSI05-1999 Section 1. General 1 General 1.1 Scope This specification covers Type MPO fibre optic connector sets. Type MPO defines a multiway connector characterised by a rectangular ferrule nominally 6,4mm 2

23、,5mm which utilises two pins of0,7mm diameter as its alignment technology. It is applicable to a joint of multiple fibres by arranging them between two pin-positioning holes in the plug. The connector includes a push-pull coupling mechanism and a ferrule spring loaded in the direction of the optical

24、 axis. The connector has a single male key which may be used to orientate and limit the relative position between the connector and the component to which it is mated. The specification contains the requirements for Type MPO connector sets. Detail specifications shall be prepared using the following

25、 proforma general blank detail specifications associated with the generic specification. For example:- Environmental Category II EN186002 When completed, the detail specifications (DSs) applicable to this sectional specification (SS) shall be re-numbered in accordance with CECC00700 (Section IV) Iss

At the time of publication, the editions indicated were valid. All standards

27、are subject to revision, and parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent editions of the standards listed below. References made to a specific clause or sub-clause of a standard include all sub-clauses to the reference unless

28、 otherwise specified. EN186000-1, Generic Specification for Connector Sets for Optical Fibres and Cables. IEC825, Radiation safety of laser products, equipment. 1.3 Definitions All necessary definitions are given in EN186000-1. 1.4 Safety 1.4.1 Optical fibre connectors, when used as part of an optic

29、al fibre system, may emit/produce potentially hazardous radiation. The manufacturers of connectors are not obliged to mark them as such; but sufficient information should be made available in the manufacturers literature to enable the system designer to assess the degree of hazard. This information

30、shall be given prominence in the detail specification (DS). 1.4.2 The assembly instructions, included in the connector package, shall give a prominent warning to the assembler, of the necessary safe work practices. 1.4.3 The responsibility for the safe application of the connector lies with the syst

31、em design engineer, who should refer to IEC825. As there is no safety guide for light emitting diodes (LEDs), IEC825 shall apply to systems using these also. 1.4.4 DSs should give the following information in a prominent position:- WARNING “Care should be taken when handling small diameter optical f

32、ibre, to prevent it puncturing the skin especially in the eye area. Direct viewing of the end of an optical fibre or a terminated optical fibre, while it is propagating energy is not recommended unless prior assurance has been obtained as to the safe energy of the output level.” 1.5 Marking See 2.6
