30、tor set (plug/ adaptor/ plug) should 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 Europea
31、n 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, th
32、e resulting level of attenuation 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
33、C B C B 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 the product in this environment is 20 years, compliance with this
34、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 manufacturing consistency of the product. This should be maintained using a r
35、ecognised quality assurance programme. BS EN 50377-13-3:2011 7 EN 50377-13-3:2011 2 Normative references The following referenced documents are indispensable for the application of this document.

45、e position plug connector set of plug/ adaptor/ plug configuration characterised by cylindrical, spring loaded butting ferrules of 1,25 mm nominal diameter and a latched push-pull coupling mechanism. The optical alignment mechanism of the connectors is of a resilient sleeve style. 3.2 Plug The plug
46、features a cylindrical zirconia ceramic ferrule and a latched push-pull mechanism. It has a single male key which is used to limit and may be used to orientate, the relative rotation between mated connectors. A cover (dustcap) to protect the ferrule endface is integrated in the connector. 3.3 Duplex
47、 adaptor The adaptor has a zirconia ceramic resilient alignment sleeve. Alternative materials may be used for the sleeve that have directly compatible material properties with zirconia, but the endface and performance requirements shall be met under all conditions. The mounting style can be: a) squa
48、re flange - 2 hole fixing; b) square flange - clip fixing. Covers (dustcaps) are integrated in each port of the adaptor. 3.4 Materials Materials which are not specified or which are not specifically 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
