17、94 BSI 01-2000 2 Foreword The CENELEC Electronic Components 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 Sy
18、stem is to facilitate international trade by the harmonization 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
19、all member countries without further testing. This European Standard was prepared by CECCWG26, Fibre Optic Connectors. The text of the draft based on document CECC86130Issue1:1993 was submitted to the formal vote for conversion to a European Standard; together with the voting report, circulated as d

Type LSA defines single way connectors with aM5,5mm 5mm screw thread coupling mechanism and a cylindrical butting ferrule of2,5mm nominaldiameter. This specification conta
25、ins the requirements for type LSA connector sets. 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 t
26、his SS shall be renumbered in accordance with CECC00700 (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 st

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
30、specified with a quality grade. This value gives 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 numbe
31、r, running from0(tightest tolerance) to5(seeAnnex 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 info
32、rmation is only applicable for field mountable connectors. The eccentricity grade is given by a number, running from0(lowest tolerance) to5. 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 c
33、onsiderable for pigtailed connector sets. The attenuation grade is given by a number, running from0(lowest tolerance) to5. The allocation of the grade and tolerance field is described in the relevant DSEN186130:1994 6 BSI 01-2000 1.3.4 quality grade this gives the combination of clearance grade, ecc
34、entricity 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 optical fibre system, may emit/produce potentially hazardous radiation. The manu
35、facturers 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 shall be given prominence in the DS. 1.4.2 The assembly instructions, inclu
36、ded 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 should refer to IEC825. As there is no safety guide for light emitting diodes (
37、LEDs), IEC825shall 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 puncturing the skin especially in the eye area. Direct viewing of the end of an optic
38、al 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.
