20、00:1999 BSI 03-2000 5 Section 1. General 1.1 Scope This sectional specification covers a family of single way fibre optic connector sets which are classified as type MSC. Type MSC is a connector set of the plug-adaptor-plug configuration. It features a push-pull coupling mechanism and cylindrical bu
21、tting ferrules. The optical alignment mechanism is a split sleeve contained within the adaptor. The specification contains the requirements for type MSC connector sets. Detail specifications (DSs) shall be prepared using the following pro forma general blank detail specifications (BDSs) associated w
22、ith 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: 1.2 Related documents The following standards contain provisions
23、 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 encouraged to investigate the possibility of applying the most re
24、cent 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.

26、resentation. 1.3 Definitions All necessary definitions are given in EN 186000-1. 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 manufacturers of connectors are not obliged to mark them as such, but suffic
27、ient 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 detail specification (DS). 1.4.2 The assembly instructions, included in the connector package, shall give a promin
28、ent 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 system design engineer, who should refer to IEC60825-1. As there is no safety guide for light emitting diodes (LEDs), IEC60825-1 shall apply to systems
29、 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 optical fibre or a terminated optical f
30、ibre, 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 See2.6 of EN186000-1.

The coupling sleeve shall be movable toward the right-and the left-directions. These dimensions are given when the coupling sleeve is moved in its most right
37、-direction position. 3. The dimension J is given for the plug endface when not mated. Note that the ferrule is movable by a certain axial compression force with direct contacting end faces, and therefore the dimension J is variable. Ferrule compression force shall be 5,5 N to 6,5 N when the position
38、 of the optical datum target from the datum X is moved in the range of 3,9 mm to 4,1 mm. In addition, the dimension J shall become less than 3,25 mm with a relatively large axial compression force. 4. The dimension Q shall be negative when the outer sleeve is in the extreme left position. 5. The dom
39、e eccentricity of the spherical polished endface shall be 50 4m maximum. For angled polished endfaces the dome offset shall be measured not only in the nominal position of the ferrule in the plug, but also in the extreme positions while rotated within the plug.
