29、d contains the initial, start of life dimensional, optical, mechanical and environmental performance requirements which a connector terminated with cylindrical zirconia PC ferrule and assembled singlemode resilient alignment sleeve SC-PC simplex connector set (plug/adaptor/plug), adaptor and patchco
30、rd must meet in order for it to be categorised as an EN standard product. Since different variants and grades of performance are permitted, product marking details are given in 3.6. 1.2 Intermateability Although all products conforming to the requirements of this European Standard will intermate, th
31、e resulting 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 attenuat
32、ion cannot 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. Table 1 Ensured level of random attenuation Plug attenuation grade C B C C C B C B A simplex plug can be
33、 connected in a duplex adaptor without degrading its level of performance. 1.3 Operating environment The tests selected combined with the severities and durations are representative of a category U environment described in EN 61753-1. 1.4 Reliability Whilst the anticipated service life expectancy of
34、 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 reliability assessment programme. 1.5 Quality assurance Compliance with this specification does not guarantee the manufactur
35、ing consistency of the product. This should be maintained using a recognised quality assurance programme.

45、eral The SC-PC connector is a single position plug connector set of plug / adaptor / plug configuration characterised by a cylindrical, spring loaded butting ferrules of 2,5 mm nominal diameter and a push-pull coupling mechanism. The optical alignment mechanism of the connector is of a resilient sle
46、eve style. 3.2 Plug The plug features a cylindrical zirconia ceramic ferrule and a push-pull coupling mechanisms. The plug housing has a single male key, which is used to limit the relative rotation between mated plugs. A cover (dust cap) to protect the ferrule end face when the connector is in the
47、unmated condition shall be provided. 3.3 Adaptor The adaptor has a zirconia ceramic resilient alignment sleeve. The mounting style is a rectangular flange simplex. Covers (dust caps) are provided to protect each port of the adaptor. 3.4 Materials Materials which are not specified or which are not sp
48、ecifically described are left to the discretion of the manufacturer. 3.5 Dimensions 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 EN Interface Standard this is clearly stated. 3.6 Colour and marking Marking of the product shall be in the following order of precedence: identification of manufacturer; manu
