27、cification contains the initial, start of life dimensional, optical, mechanical and environmental performance requirements which a terminated and assembled singlemode MF 4-fold-connector set (for backplane applications) must meet in order to be categorised as an EN standard product. Since different
28、variants and grades of performance are permitted, product marking details are given in 3.5. 1.2 Intermateability Although all products conforming to the requirements of this standard will intermate, the resulting level of random attenuation performance will only be ensured in accordance with Table 1
29、. The intention is that this will be true irrespective of the manufacturing source(s) of the product. When intermating plug variants having different attenuation grades, the resulting level of attenuation can not be assured to be any better than the worst attenuation grade. The intermating of a grad
30、e C plug with a grade B plug will result in an uncertain level of random attenuation performance. Table 1 - Ensured level of random attenuation Plug variant/Attenuation grade C B C C C B C B 1.3 Operating environment The tests selected combined with the severities and durations are derived from the
31、category C environment, according to EN 61753-1. 1.4 Reliability Whilst the anticipated service life expectancy of the product in this environment is 20 years, compliance with this specification does not guarantee the reliability of the product. This should be predicted using a recognised reliabilit
32、y assessment programme. 1.5 Quality assurance Compliance with this specification does not guarantee the manufacturing consistency of the product. This should be maintained using a recognised quality assurance programme. 2 Normative references The following referenced documents are indispensable for

40、tor set of plug and socket configuration characterised by a rectangular, spring loaded butting ferrule with up to 12 fibres and a backplane coupling mechanism. The optical alignment mechanism of the connectors is of a precision pin and hole type. 3.1 Plug The plug features a rectangular thermo plast
41、ic composite ferrule and a latched coupling mechanism. A cover (dustcap) to protect the ferrule endface when the connector is in the unmated condition shall be provided. 3.2 Housings The housings B2 and B3 (see Annex B) have no role in the final alignment mechanism. The mounting style is: EN 61076-4
42、-100 Back plane MF-A/MF-B See Annex A. Covers (dustcaps) shall be provided to protect each port of the adaptor. 3.3 Materials Materials which are not specified or which are not specifically described are left to the discretion of the manufacturer. The material for the ferrule is Polyphenylene Sulphi
43、de (PPS) material with a Youngs modulus of 20 GPa nominal and guide pins which are of stainless steel. Alternative materials, which have compatible material properties, may be used as long as endface and performance requirements are met under all conditions as specified in this document. 3.4 Dimensi
44、ons Outline dimensions and other dimensions necessary to ensure intermateability or which affect performance are specified. All other dimensions are left to the discretion of the manufacturer. Where the mating face limit dimensions are not in agreement with an IEC interface this is clearly stated. B
