28、uct definition This European Standard 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 LSH-PC simplex connector set (pl
29、ug/adaptor/plug), adaptor and patchcord 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 3.5. 1.2 Intermateability Although all products conforming to the requirements of this
30、 standard will intermate, the 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
31、 resulting level of attenuation can 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. Table 1 - Ensured level of random attenuation Plug variant / Attenuation gr

33、e with this standard 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 standard does not guarantee the manufacturing consistency of the product. This should be maintained using a
34、 recognised quality assurance programme. EN 50377-8-9:2007 - 6 - 2 Normative references The following referenced documents are indispensable for the application of this document.
