29、06:16, Uncontrolled Copy, (c) BSIEN 50377-11-1:2008 6 1 Scope 1.1 Product definition This specification 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 a
30、pplications) must meet in order to be categorised as an EN standard product. Since different 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 resu
31、lting level of random attenuation performance will only be ensured in accordance with Table 1. 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 ca
32、n not be assured to be any better than the worst attenuation grade. The intermating of a grade C plug with a grade B plug will result in an uncertain level of random attenuation performance.

33、vironment The tests selected combined with the severities and durations are derived from the 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 gua
34、rantee the reliability of the product. This should be predicted using a recognised reliability 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 assuranc
35、e programme. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.

43、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 plastic composite ferrule and a latched coupling mechanism. A cover (dustcap) to protect the ferrule endface when
44、 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 61076-4-100 Back plane MF-A/MF-B See Annex A. Covers (dustcaps) shall be provided to protect each port of the adapt
45、or. 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 Sulphide (PPS) material with a Youngs modulus of 20 GPa nominal and guide pins which are of stainless steel. Alter
46、native 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 Dimensions Outline dimensions and other dimensions necessary to ensure intermateability or which affect performance
47、 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.
