19、onents Committee (CECC) is composed of those member countries of the European Committee for Electrotechnical Standardization (CENELEC) who wish to take part in a harmonized System for electronic components of assessed quality. The object of the System is to facilitate international trade by the harm
20、onization of the specifications and quality assessment procedures for electronic components, and by the grant of an internationally recognized Mark, or Certificate, of Conformity. The components produced under the System are thereby acceptable in all member countries without further testing. This Eu

The text of the draft based on document CECC 86130 Issue 1:1993 was submitted to the formal vote for conversion to a European Standard; together with the voting report, circulated as document CECC (Secretariat) 3468 it was approved

27、on 1. General 1.1 Scope This SS covers type LSA fibre optic connector sets. Type LSA defines single way connectors with a M 5,5 mm 5 mm screw thread coupling mechanism and a cylindrical butting ferrule of 2,5 mm nominal diameter. This specification contains the requirements for type LSA connector se
28、ts. Detail specifications (DSs) shall be prepared using the following pro forma general blank detail specifications (BDSs) associated with the generic specification. For example: EN 186005 Environmental Category V. When completed, the DSs applicable to this SS shall be renumbered in accordance with
29、CECC 00700 (Section IV) Issue 1, clause 4.2, as follows. For example: CECC 86135-XXX Type LSA Environmental Category V 1.2 Related documents The following standards contain provisions which, through reference in this text, constitute provisions of this standard. At the time of publication, the editi
30、ons indicated were valid. All standards 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 subclause of a standard includes
31、 all subclauses to the reference unless otherwise specified. EN 186000-1, Generic specification (GS) for connector sets for optical fibres and cables Part 1.

32、 tolerancing principle. ISO 128, Technical drawings General principles of presentation. 1.3 Definitions For comparison of connectors with different accuracy grades with different mechanical and optical quality grades within the same DS the connectors are specified with a quality grade. This value gi
33、ves a combination of the following three subgrades: * clearance grade * eccentricity grade * attenuation grade. 1.3.1 clearance grade this describes the tolerance field of the leading diameter of ferrule and sleeve. The clearance grade is given by a number, running from 0 (tightest tolerance) to 5 (
34、see Annex 2). The allocation of clearance grade and tolerance field is described in the relevant DS 1.3.2 eccentricity grade this describes the tolerance field that combines the tolerance of the borehole and its concentricity to the axis of the plug. This information is only applicable for field mou
35、ntable connectors. The eccentricity grade is given by a number, running from 0 (lowest tolerance) to 5. The allocation of grade and tolerance field is described in the relevant DS 1.3.3 attenuation grade this describes an area of a given attenuation. It is only considerable for pigtailed connector s
36、ets. The attenuation grade is given by a number, running from 0 (lowest tolerance) to 5. The allocation of the grade and tolerance field is described in the relevant DS Licensed Copy: sheffieldun sheffieldun, na, Sun Oct 29 10:47:06 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN 186130:1994 6 BSI 01-
37、2000 1.3.4 quality grade this gives the combination of clearance grade, eccentricity grade and attenuation grade the quality grade is given by the highest number of the three mentioned subgrades Example: Pigtailed connector set 1.4 Safety 1.4.1 Optical fibre connectors, when used as part of an optic
38、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
39、shall be given prominence in the DS. 1.4.2 The assembly instructions, included in the connector package, shall give a prominent warning to the assembler, of the necessary work practices. 1.4.3 The responsibility for the safe application of the connector lies with the system design engineer, who shou
40、ld refer to IEC 825. As there is no safety guide for light emitting diodes (LEDs), IEC 825 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 fibre, to prevent it punctur
41、ing 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 of EN 186000-1.
