20、it dimensions 8EN186260:1997 BSI 04-1999 5 1 General 1.1 Scope This sectional specification covers a family of single way fibre optic connector sets which are classified astype SC. Type SC is a connector set of the plug-adaptor-plug configuration. It features a push-pull coupling mechanism and cylin
21、drical butting ferrules. The optical alignment mechanism is a split sleeve contained within the adaptor. The specification contains the requirements for type SC connector sets. Detail specifications (DSs) shall be prepared using the following pro forma general blank detail specifications (BDSs) asso
22、ciated with the generic specification. For example: EN 186005 for environmental category V. When completed, the DS(s) applicable to this SS shall be numbered in accordance with CECC00700 (Section IV) Issue1, clause4.2, as follows. For example: CECC86265-000, Type SC, environmental category V. 1.2 Re
23、lated documents The following standards contain provisions which, through reference in this text, constitute provisions of this standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this standard are encoura
24、ged 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 includes all sub-clauses to the reference unless otherwise specified. EN 186000-1, Generic specification for connectors for optical

26、ibre Connectors, when used as part of an Optical 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
27、assess the degree of hazard. This information 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 a
28、pplication of the connector lies with the system design engineer, who should refer to IEC825-1. As there is no safety guide for light emitting diodes (LEDs), IEC825-1 shall apply to systems using these also. 1.4.4 DSs should give the following information in a prominent position: WARNING “Care shoul
29、d 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 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
30、 energy of the output level”. 1.5 Marking See 2.6 of EN186000-1. 2 Requirements The requirements specified in sections 2 and 3 of EN186000-1 apply. The requirements for connector sets components covered by this specification are as specified herein and in the relevant DS. 2.1 Classification The conn
31、ector sets covered by this specification are classified as: Type: type 1: SC, coupling mechanism: push-pull, configurations: plug / adaptor / plug Arrangements: kit, pigtail, patchcord.EN186260:1997 6 BSI 04-1999 Environmental categories: the DS-writer shall select the appropriate BDS for the chosen
32、 environmental category. Assessment levels: level A, level B, level C. The single limit (maximum or minimum) mating face dimensions for connector set configurations are given in Figure 1 and Figure 2.
